using the equaation 2h2+o2-->2h2o if 10.0g of hydrogen are used in the presence of excess oxygen how many grams of water will
astra-53 [7]

Answer:

90g of H2O

Explanation:

2H2 + O2 —> 2H2O

First, we calculate the molar masses of H2 And H20.

Molar Mass of H2 = 2g/mol

Mass conc of H2 from the balanced equation = 2 x 2 = 4g

Molar Mass of H2O = 2 + 16 = 18g/mol

Mass conc of H2O from the balanced equation = 2x18 = 36g

From the equation,

4g of H2 produced 36g of H2O

Therefore, 10g of H2 will be produce = (10x36)/4 = 90g of H2O

When gases dissolve in gases or when liquids and gases dissolve in liquids, _________eventually spreads the particles evenly thr
natulia [17]

When gases dissolve in gases or when liquids and gases dissolve in liquids, particles movement eventually spreads the particles evenly throughout the solvent resulting in a homogeneous mixture.​

Explanation:

When gases dissolve in gases or when liquids and gases dissolve in liquids, particle movement eventually spreads the particles evenly throughout the solvent resulting in a homogeneous mixture.​

Solid particles do not dissolve easily like liquids and gases dissolve. Solid particles when dissolved in solid the particles moves very little. After getting heated and becomes molten then they get mixed.

But in the liquids and gases atoms moves and the particles get eventually spread and also get mixed after cooled.
