Tetraphosphorus Decaoxide has a molecular formula of P4O10,
all else are known. Therefore the balanced chemical equation would be:
4PH3 + 8O2 --> 6H2O + P4O10
Taking into account the phases:
4PH3(g) + 8O2(g) --> 6H2O(g) + P4O10(s)
Answer:
Answer in explanation
Explanation:
In the first case, we divide each of the masses by the respective atomic masses:
N =0.615/14 = 0.043928571428571
O = 0.703/16 = 0.0439375
It can be seen here that the values are similar, hence the formula is NO
now let us look at the second data set:
N = 1.27/14 = 0.090714285714286
O = 2.9/16 = 0.18125
We now divide by the smallest
N = 090714285714286/090714285714286 = 1
O = 0.18125/090714285714286 = 2
The formula here is thus NO2.
It can be seen that there are different oxides of nitrogen here which clearly indicates the law of multiple proportion.
Aluminum to hydrogen gas ratio is 2 : 3 by looking at the coefficients of aluminum on the reactant side and hydrogen gas on the product side.
So from 2.0 mol of Al, 3.0 mol of H2 would form.
