A) How many moles of CO2 and H2O are formed from 3.85 mole of propane C3H8 (This calculation needs to be done twice-once fro CO2
castortr0y [3046]

Answer:

11.55 moles of CO2 gas result from 3.85 moles of propane.

15.4 moles of H2O result from 3.85 moles of propane.

b) 0.5176 moles of water result from 0.647 moles of oxygen gas.

0.1294 moles of propane are reacted.

Explanation:

C_3H_7+5O_2\rightarrow 3CO_2+4H_2O

a) Amount of propane = 3.85 moles

The reaction indicates that for every mole of propane, 3 moles of carbon dioxide are produced.

Thus, 3.85 moles of propane yield:

\frac{3}{1}\times 3.85 mol=11.55 mol of carbon dioxide.

11.55 moles of CO2 gas result from 3.85 moles of propane.

The reaction also specifies that 1 mole of propane produces 4 moles of water.

Therefore, 3.85 moles of propane will generate:

\frac{4}{1}\times 3.85 mol=15.4 mol of water.

15.4 moles of H2O result from 3.85 moles of propane.

b) Amount of oxygen gas = 0.647 moles

The reaction states that 5 moles of oxygen yield 4 moles of water.

As a result, 0.647 moles of oxygen will produce:

\frac{4}{5}\times 0.647 mol=0.5176 mol of water.

0.5176 moles of water result from 0.647 moles of oxygen gas.

The reaction indicates that 5 moles of oxygen gas interact with 1 mole of propane.

Then, 0.647 moles of oxygen will cause:

\frac{1}{5}\times 0.647 mol=0.1294 mol of propane to react.

0.1294 moles of propane are reacted.

What is the net ionic equation of the reaction of mgso4 with sr(no3)2? express you answer as a chemical equation including phase
castortr0y [3046]
MgSO4 and Sr(NO3)2 are soluble, leading to the following ionic equation: Mg+2 + SO4-2 + Sr+2 + 2NO3-1 → Mg+2 + 2NO3-2 + SrSO4. Since SrSO4 is insoluble, we cancel out Mg and 2NO3 from both sides, resulting in the net ionic equation: SO4-2 + Sr+2 → SrSO4
