14 moles of water How many moles of oxygen and hydrogen must react?
Answer: 7 moles hydrogen and 3,5 moles oxygen.
2 atoms (molecules) of hydrogen are needed to react with oxygen to form water.
The relative number of moles of hydrogen to moles of oxygen that react to form water represents what?
The ratio H/O is 2.
How many moles of hydrogen gas are needed to react with 0.50 mole of oxygen to form one mole of water?
The chemical equation for hydrogen gas and oxygen gas combining to form water is as follows: 2H2 (g) + O2 (g) ---> 2H2O (l). This means that for every 1 mole of oxygen gas reacting, two moles of hydrogen gas are needed. So if 0.50 moles of oxygen gas react to form one mole of water, then one mole of hydrogen gas was used.
No. Hydrogen and oxygen react with each other to form water.
How many moles of hydrogen gas would be needed to react with excess carbon dioxide to produce 76.6 moles of water vapor?
This is the Sabatier reaction or Sabatier process (the reaction of hydrogen with carbon dioxide at elevated temperatures and pressures in the presence of a nickel catalyst to produce methane and water) CO2 + 4H2 → CH4 + 2H2O The hydrogen is required both to react with the carbon and the oxygen and all of this must be accounted for to produce the 76.6 moles of water. From the equation 4 moles of hydrogen reacts… Read More
If 4 moles of hydrogen is completely oxidized with oxygen how many moles of oxygen will be consumed?
4 moles of hydrogen consume 2 moles of oxygen for complete oxidation to water.
Well if one mole of water = 2 moles of hydrogen and 1 mole of oxygen, than 2moles of water = 4 moles of hydrogen and 2moles of oxygen.
Both oxygen and hydrogen under normal conditions contain two atoms per mole. 4 moles of oxygen therefore contain 8 moles of oxygen atoms, which is sufficient to make 8 moles of water, since water contains only one oxygen atom per molecule. The 16 moles of hydrogen contain 32 moles of hydrogen atoms. Only 16 moles of hydrogen atoms are needed to make 8 moles of water, which contains 2 hydrogen atoms per mole. Therefore, oxygen… Read More
Hydrogen and oxygen undergo combination reaction to form water. When hydrogen and oxygen react together, water is formed.
45,3 moles of water
None. You need Oxygen to form water, not just Hydrogen.
Hydrogen plus oxygen creates water
Hydrogen and oxygen react with each other to create water.
How many water molecules are created when 32 grams of oxygen react completely with 4 grams of hydrogen?
To the justified number of significant digits, the masses given correspond to one mole of diatomic oxygen and two moles of diatomic hydrogen. The formula of water is H2O; therefore, these numbers of moles produce two moles of water molecules, and the number of the latter is twice Avogadro's number = 1.2 X 1024.
Hydrogen gas and oxygen gas react to form what water (H2O).
How many grams of hydrogen are needed to produce 30.0 grams of water and how many grams of hydrogen are needed to react with 25.0 grams of oxygen Thanks for the help I'm a bit lost?
The synthesis reaction is 2 H2 + O2 = 2 H2O. Every two moles of hydrogen reacts with one mole of oxygen to make two moles of water. Then 30.0 grams of water is 1.67 moles, and 1.67 moles of H2 has a mass of 3.37 grams. 25.0 grams of O2 is .781 moles, so 1.562 moles of H2 are needed, or 3.15 grams.
How many moles of hydrogen gas would be needed to react with excess carbon dioxide to produce 42.1 moles of water vapor?
84,2 moles hydrogen are needed.
The amount of water formed from a reactionof hydrogen and oxygen conforms to the chemical equation: 2H2 + O2 --> 2H2O For every two moles of hydrogen which reacts with one mole of oxygen, 2 moles of water are formed.
Hydrogen an react with oxygen to form water and not helium
Hydrogen and oxygen will react explosively to form water.
For the reaction 2H2 plus O2 equals 2H2O how much water is produced when 2.5 moles of hydrogen react completely How do you do the problem?
2H2 + O2 ---------------> 2H2O for every 2 moles of hydrogen that reacts, 2 moles of water are produced, thus a 1:1 ratio of water produced to hydrogen reacted. So:- 2.5 moles of hydrogen reacted will produce 2.5 moles of water
2H2 + O2 --> 2H2O As you can see by the balanced reaction, for every 1 mole of oxygen used, 2 moles of water are formed. Also notice that for every 1 mole of oxygen used, you need 2 moles of hydrogen to produce the 2 moles of water. So in your case 110 moles of oxygen would produce 220 moles of water & would also require 220 moles of hydrogen (which you have in… Read More
The most common compound of hydrogen and oxygen is better known as "Water". Hydrogen and oxygen also forms Hydrogen Peroxide.
There are two moles of hydrogen atoms and one mole of oxygen atoms in one mole of water. It takes two hydrogen atoms and one oxygen atom to make one molecule of water.
The balanced equation for the synthesis of water from hydrogen and oxygen is: 2H2 + O2 --> 2H2O. If you have 1.4 moles of hydrogen, you will produce 1.4 moles of water because the molar ratio of hydrogen to water in this reaction is 2:2, which is the same as 1:1, which is the same as 1.4:1.4.
What compound? Please copy your homework questions completely. How else can we help you cheat? To find the number of moles of oxygen (or any other element), multiply the number of atoms present on the molecule (in subscript) by the number of molecules present in the reaction (in standard script to the left of the molecule) In this case: 2 H2 + O2 --> 2 H2O On the reactant side (to the left of the… Read More
No metals react to form water. The two nonmetals that react to form water are hydrogen and oxygen.
The formula for Oxygen gas is O2, and the formula for water is H2O. Each molecule of Oxygen gas can produce 2 molecules of water (with enough Hydrogen, of course). So, 2.5 moles of Oxygen gas would be required to produce 5.0 moles of water.
Not all metals react with water, but some, such as metallic sodium, do react quite vigorously with water. In a sense it is true that when metals react with water it is the same as reacting with oxygen, because the water molecule (H2O) does contain oxygen, and it is the oxygen in the water molecule with which metals react. Metals do not react with the hydrogen content of the water molecule, so when metal reacts… Read More
Write out the equation first: 10H2 + 10O2 --> xH2O Since there are 2 moles of Hydrogen for every mole of Oxygen and equal moles of both are given, the Hydrogen limits the reaction as the limiting reactant. 10 moles of Hydrogen can make 10 moles of H2O with 5 moles of Oxygen left over. Think of it logically: H2 is two hydrogen atoms and water needs two hydrogen atoms, so it is a one-to-one… Read More
How many grams of water are made from complete reaction of 2.2 moles of oxygen gas with hydrogen gas?
The balanced chemical equation for the reaction between oxygen and hydrogen is 2H2 + 02 -> 2H2O Thus 2.2 moles of oxygen reacts with 4.4 moles of hydrogen to form 4.4 moles of steam (water in gaseous state). The mass of H2O obtained is thus 4.4 x 18.0 = 79.2g.
Methane reacts with oxygen in the following way. CH4 + 3 O2 --> CO2 + 4 H2O. If 5 moles of oxygen react with 2.8 moles of methane, only 1.67 moles of methane would be consumed because of the molar ratio 1:3. This would produce 1.67 moles of carbon dioxide and 6.67 moles of water.
The chemical equation is 2H2(g) + O2 â†’ 2H2O(l). Two moles of hydrogen reacts with one mole of oxygen to form two moles of water.
its water because H20
Hydrogen and Oxygen.
No, this would make 5 moles. This is because water is H2O. This means that for each oxygen molecule used, there will be 2 hydrogen molecules used. In the given equation Only 5 moles of oxygen could be used to pair with all 10 moles of hydrogen, therefore giving you an excess of 5 oxygen molecules.
3 moles of water molecules. 6 moles of hydrogen atoms. 3 moles of oxygen atoms. 30 moles of electrons. 30 moles of protons. etc.
2 Hydrogen atoms and 1 Oxygen atom= water molecule
by moles --- 2 by weight -- .25
75g/18gmol-1 = 4.167 moles of water molecules, composed of 4.167 moles of oxygen atoms and 8.334 moles of hydrogen atoms.
No, if you have a contained filled with hydrogen and oxygen gas you have separated hydrogen molecules (H2) and oxygen molecules (O2). In water the hydrogen and oxygen are bonded to each other in water molecules (H2O). However, if you apply enough heat to a mixture of hydrogen and oxygen gas the two will react and water will be the product.
Because hydrogen and oxygen require specific conditions to react and form water, which are not met in the normal surroundings.
The mass of the oxygen and hydrogen that react to form water will be exactly equal to the mass of the water produced.
Water is 18 grams to the mole, so 5.3 moles of water is 95.4 grams. Hydrogen makes up 11% by mass of water, and 11% of 95.4 is 10.5 grams of hydrogen. That's about 10.5 moles of hydrogen, which at STP would be 235.2 liters. - - - - - Or we could go at it this way: The formula for water is H2O. At least that's what my chemistry teacher told me when he… Read More
Hydrogen and oxygen react chemically to form water how much waternwould be formed if 4.8 grams of hydrogen reacted with 38.4 grams of oxygen?
43.2 grams of water
Sodium and water, in absence of air or oxygen, react to produce hydrogen gas and sodium hydroxide. When there is a slight amount of oxygen in the reaction mixture this will immediately and explosively react with hydrogen to form water. That's why this is a dangerous reaction.
They chemically bond together t form molecules of H2O.
Yes. Fluorine reacts with water to form hydrogen fluoride and oxygen.
This reaction?? 2H2O -> 2H2 + O2 this would be one to one and you would get; 174.82 moles of water vapor Without an equation I do not really know what you mean.
The reaction of potassium with water is highly exothermic. That is, it gives off a lot of heat. Hydrogen, which is formed by the chemical reaction is ignited by this heat and so explodes.
