What is the answer for this Suppose you had one mole of oxygen (O2). How many moles of hydrogen (H2) would react completely with the oxygen and how many moles of H2O would be produced?

Here is the BALANCED reaction eq'n. 2H2(g) + O2(g) = 2H2O(l) The prefix number are the Molar Ratios 2:1::2 So oxygen is ONE(1) mole Hence hydrogen is TWO(2) moles It produces TWO(2) moles of water.


How many moles of oxygen would be needed for the complete combustion of the 3 moles of the hydrogen?

1 mole


How many moles of hydrogen cyanide would be produced from the complete reaction of 10 moles of oxygen gas?

Absolutely none, as there is no oxygen in hydrogen cyanide. Its formula is HCN--one atom each of hydrogen, carbon and nitrogen.


How many moles of water are formed with 230 moles of H2 and 110 moles of O2?

2H2 + O2 --> 2H2OAs 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 excess since you have 230 moles of hydrogen). So 220 moles of water are the most that can be formed.


How many moles of nitrogen would be needed to completely react with 12 moles of hydrogen according to the balanced equation given below?

N2 + 3H2 -> 2NH3 3 moles hydrogen gas. You should know that because of the formula of ammonia.


How would you find the answer to this question How many moles of HCl can be formed when moles of hydrogen gas react with chlorine?

For each mole of hydrogen gas (H2) reacting with chlorine gas (Cl2), you will get 2 moles of HCl. H2 + Cl2 = 2 HCl


How many moles of water are produce when 45.3 moles of hydrogen reacts with oxygen?

Since hydrogen is a gas, we would need more information to answer it. As chance wrote, you will need twice as much hydrogen as oxygen. However, in order to know what the volume of that hydrogen is, we also need to know the temperature and pressure so that we can use the universal gas law to get the answer.


Does 10o2 plus 10H2 make 20 moles of water?

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.


How many moles of water vapor react to yield 174.82 moles of hydrogen?

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.


How would you test carbon dioxide to show that it was hydrogen?

Carbon dioxide form a milky suspension of calcium carbonate in calcium hydroxide; hydrogen doesn't react. But hydrogen react with oxygen when a flame exist.


If you have 0.50 mole of Ca how many atoms are present?

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 H2OOn the reactant side (to the left of the arrow), there are 4 moles of hydrogen present because we have inserted 2 moles of diatomic hydrogen (multiply the subscript 2 by the standard script 2 to the left of the molecule). We can calculate that there are 2 moles of oxygen present because we have inserted one mole of diatomic oxygen. On the products side (the right side of the arrow) we produced 2 moles of water (indicated by the standard script 2 to the left of the molecule) Each molecule of water contains 2 molecules (2 moles) of hydrogen and one molecule (one mole) of oxygen. Thus, we have a balanced equation because this gives us 4 moles of hydrogen and 2 moles of oxygen, just like we had on the reactant side.The multipliers in standard script to the left of the molecule gives us the molar ratio. 2 moles of diatomic hydrogen react with 1 mole of diatomic oxygen to produce 2 moles of water. Thus, if we were to burn .5 moles of diatomic hydrogen in excess oxygen, we would produce .5 moles of water. This is because, by looking at our chemical equation, we see that the molar ratio of diatomic hydrogen to water is 2:2 (or 1:1). We would have .25 moles of oxygen because the ratio of hydrogen to oxygen is 4:2 (or 2:1).Were this the question on your homework, the answer would be ".25 moles"


How many moles of hydrogen gas would be needed to react with excess carbon dioxide to produce 30.6 moles of water vapor?

CO2 + H2 -> CO + H2O one to one here 30.6 moles H2O (1 mole H2/1 mole H2O) = 30.6 moles Hydrogen gas needed
