The structures of both acetone and propanal are shown below:
In the formula of propanal there is -CHO functional group at the end.
In acetone -CO- group is present in the middle that is on the second carbon.
The molecular formula is C3H6O.
Both have same molecular formula but different structural formulas.
Answer:
10.85 g of water
Explanation:
First we write the balanced chemical equation
Then we calculate the number of moles of nitric acid produced
n(HNO3) =
According to the balanced equation, water needed in moles is always half the number of moles of HNO3 produced. So since we will produce 1.2044 mol of HNO3, we will need 0.6022 mol of water. Now to calculate what mass that is:
mass(water)=number of moles*molar mass=0.6022mol*18.02g/mol=10.85g
Answer:
0.9307 moles have been introduced into the bag.
Explanation:
Pressure of the gas within the bag,P = 1.00 atm
Temperature of the gas remains at room temperature,T=20.0 °C = 293.15 K
Volume of the gas in the bag = V = 22.4 L
Number of moles of gas = n
Using an ideal gas equation:
n = 0.9307 moles
0.9307 moles have been introduced into the bag.
