Weather a thing is solid, liquid or gas depends upon the force of the bonds between the molecules, and that depends one temperature and pressure, as well as the particular molecule.
In a solid force between molecules is greater as then the forces between molecules of the same material as a liquid, and in a liquid is greater than in a gas.
So in the environments most often found on the surface of the earth, hydrogen as a molecule consisting of two hydrogen atoms is always a gas, but water, consisting of two hydrogen atoms and one oxygen atom, can be solid (ice), liquid (water) or gas (water vapor), depending on the temperature and pressure. when you boil water, you turn the liquid into a gas. When you freeze water, you turn the liquid into a solid.

Which equation has water as a product in the chemical reaction-?
bromine water? The reaction between hexene, bromine, and water is an addition reaction.
Is h2o plus energy to h2 plus o2 an exothermic reaction?
No. It is endothermic because it absorbs energy.
If a sample of pure hydrogen gas is ignited very carefully the hydrogen burns gently combining with the oxygen gas of the air to form water vapor write the unbalanced chemical equation for this react?
H2(g) + O2(g) --> H2O(l) unbalanced. 2H2(g) + O2(g) ==> 2H2O(l) balanced.
Why H2 CO called water gas?
"H2 CO" is not typically referred to as "water gas". "Water gas" is a mixture of hydrogen (H2) and carbon monoxide (CO) produced by reacting steam with heated carbonaceous materials such as coal. It is called water gas because steam (water vapor) is a key component in its production.
What two gases make up H2o?
The formula for H2O is two hydrogen molecules and one oxygen molecule.
Is hydrogen h2o?
No. Hydrogen gas is H2. H2O is water.
What is the gas which burns to form water?
Hydrogen gas (H2) burns to form water (H2O). The reaction equation is as follows: 2 H2 + O2 --> 2 H2O
Which equation has water as a product in the chemical reaction-?
bromine water? The reaction between hexene, bromine, and water is an addition reaction.
What happen when water gas heated under pressure in the presence of Zn O - Cr O?
Water gas is a mixture of CO and H2 and H2O. Over oxide catalysts the "water gas shift" reaction occurs that removes the CO by reacting it with water to produce CO2 and more H2. CO + H2O -> CO2 + H2
What is the word equation for the reaction of Li Na and K with H2O?
The word equation for the reaction of Li, Na, and K with H2O is: Lithium (Li) + Water (H2O) → Lithium hydroxide (LiOH) + Hydrogen gas (H2) Sodium (Na) + Water (H2O) → Sodium hydroxide (NaOH) + Hydrogen gas (H2) Potassium (K) + Water (H2O) → Potassium hydroxide (KOH) + Hydrogen gas (H2)
Can H2 be oxidized?
Yes, hydrogen gas (H2) can be oxidized to form water (H2O) in the presence of an oxidizing agent. The oxidation reaction of hydrogen gas involves the loss of electrons.
What does Na plus H2O plus H2 equal?
The reaction of Na (sodium) with H2O (water) produces NaOH (sodium hydroxide) and H2 (hydrogen gas). So, the equation would be 2Na + 2H2O → 2NaOH + H2.
What reactions happen when hydrogen gas with oxygen gas to form water?
The reaction is:2 H2 + O2 = 2 H2O
What type reaction is NO plus h2?
The reaction between nitrogen monoxide (NO) and hydrogen gas (H2) is a combustion reaction that produces nitrogen gas (N2) and water (H2O). This reaction can be represented by the equation: 2 NO + 2 H2 → N2 + 2 H2O. It is characterized by the combination of a gas with hydrogen, resulting in the formation of new products.
Balance h2 o2 H2O?
Water (H2O) is made of 2 molecules of hydrogen and one oxygen. When you separate water into a gaseous state by electrolysing the water, you have separated the oxygen and hydrogen molecules. If you were to bubble that gas (Brown's gas) through water, the water absorbs the extra 2 molecules of hydrogen and one molecule of oxygen. 2H2O + 2H2 + O2 = 2[H3O]+ + 2[OH]-
What is the chemical formula for gas?
The chemical formula for gas is typically represented as ( gas ) or ( Gas ), as it is a general term used for any substance that is in a gaseous state at room temperature and pressure. Gas can consist of single elements (like ( O_2 ) for oxygen gas) or compounds (like ( CO_2 ) for carbon dioxide gas).
Is h2o plus energy to h2 plus o2 an exothermic reaction?
No. It is endothermic because it absorbs energy.
