MH₂: 2 g/mol
mO₂: 32 g/mol
2H₂ + O₂ ---> 2H₂O
4g......32g
4g H₂ ---- 32g O₂
Xg H₂ --- 192g O₂
X = (192×4)/32
X = 24g H₂
<u>Answer:</u> The standard free energy change of formation of is 92.094 kJ/mol
<u>Explanation:</u>
We are given:
Relation between standard Gibbs free energy and equilibrium constant follows:
where,
= standard Gibbs free energy = ?
R = Gas constant =
T = temperature =
K = equilibrium constant or solubility product =
Putting values in above equation, we get:
For the given chemical equation:
The equation used to calculate Gibbs free change is of a reaction is:
The equation for the Gibbs free energy change of the above reaction is:
We are given:
Putting values in above equation, we get:
Hence, the standard free energy change of formation of is 92.094 kJ/mol
Answer:
Basic oxides are oxides that show basic properties in opposition to acidic oxides and that either react with water to form a base; or react with an acid to form a salt and water which are called neutralization reactions.

Answer:
Chromatography is used to separate mixtures of substances into their components.They all have a stationary phase (a solid, or a liquid supported on a solid)
Explanation:
it's where the things stay still until the mobile phase moves through and takes the components
