10 moles of H2 reacts with 5 moles of O2 creating 10 moles of water.
Water has the molar mass 18 g/mole
10 · 18g = 180 g
180 g of water can be produced from 10 moles of hydrogen gas.
Answer:Iron combines with oxygen to produce rust, which is the compound named iron oxide
Explanation:
Answer:-
H+ + OH- --> H2O
Explanation:-
The chemical equation is NaOH + HNO3 --> NaNO3 + H2O
Now for the ionic compounds
HNO3 --> H+ + NO3 -
NaOH--> Na+ + OH-
NaNO3 --> Na+ + NO3-
Water being covalent will remain as H2O,
Hence
HNO3 + NaOH--> NaNO3 + H2O
H+ + NO3 - + Na+ + OH- --> Na+ + No3 - + H2O.
Crossing out common terms
H+ + OH- --> H2O
Answer:
19.4%
Explanation:
Calcium Chlorate is Ca(ClO3)2
Now calculate the molar mass of Ca(ClO3)2
Ca = 40.1
Cl = 35.5
O = 16.0
But they are two chlorine atoms and six oxygen atoms. So you do this:
40.1 + 35.5(2) + 16.0(6) = 207.1 grams
Now find the molar mass of just calcium.
There is only one calcium atom.
So you do this.
40.1(1) = 40.1
Now divide the molar mass of calcium by the molar mass of calcium chlorate.
40.1 / 207.1 = 0.1936
0.1936 rounds to 0.194
Now multiply 0.194 * 100 and you will get 19.4
So the final answer is 19.4%.

True, when small pieces of rock and animal remains weather over the years it sometimes get carried down stream then form a layer of rock. over years different types of rocks settle in the same place and compacts the rocks beneath it forming another layer.
