The first step to this question is finding the balanced chemical reaction.
H₂+1/2O₂⇒H₂O
Then you need to find the limiting reagent by finding the moles of each reactant then finding how much product each amount of reactants will form. The reactant that produces the least amount of product is the limiting reagent.
moles of H₂:
1g/(1g/mol)=1mol
moles of O₂:
10g/32g/mol=0.3125mol
moles of H₂O formed with amount of H₂:
1molH₂x(1molH₂O/1molH₂O)=1molH₂O
moles of H₂O formed with amount of O₂:
0.3125molO₂x(1molH₂O/0.5molO₂)=0.625molH₂O
Since less water is produced with the amount of oxygen given, oxygen is the limiting reagent and the moles of water formed from the oxygen is the moles of H₂O we will use to find the amount of H₂O produced.
0.625molH₂Ox18g/mol=11.25g H₂O
It will shrink, and eventually deflate because of the lack of kinetic energy.
The answer is permeability
I took my test and it was right
Model 3 is the most effective because it shows that molecules can be made out of more than one type of atom
Explanation:
The most effective model is the first model which shows that molecules can be made out of more than one type of atom
- An element is a distinct substance that cannot be split up into simpler substances.
- When elements combine together they either form compounds or molecules.
- Molecules are usually atoms that are covalently bonded together. They have very fascinating and unique properties.
- The third model perfect shows how molecules can be made up of the same atom and also different atoms.
- Atoms in molecules share their valence electrons.
