Answer and Explanation:
A combustion reaction occurs in the presence of oxygen (O2),and it gives carbon dioxide (CO2) and water (H2O) as main products.
So, in each case, we have to write O2 in the reactants side (with the given hydrocarbons), while CO2 and H2O will be in the products side:
a. Butane (C4H10):
The equation is balanced because in each side of the reaction there are: 8 C, 20 H and 26 O.
b. Cyclohexane (C6H12):
The equation is balanced because in each side of the reaction there are: 6 C, 12 H and 18 O.
Answer:
The sodium nitrate is more economical
Explanation:
Hi, to compare this two options you need to determine the amount of nitrogen per 100 lb of both and then estimate its cost:
1) Sodium nitrate
This fertilizer has 30 % by weight of sodium nitrate:
The molecular weight of sodium nitrate:
So, this salt has 14 g of N per 85 g:
Cost per gram:
2) Ammonium sulfate
This fertilizer has 20 % by weight of ammonium sulfate:
The molecular weight of ammonium sulfate:
So, this salt has 14 g of N per 114 g:
Cost per gram:
