Answer:
Explanation:
no of moles of water=8.00/18=0.4
1 mole of C2H6 produced 1 mole of CO2 and 1 mole of H2O
so for 1 mole of H2O 1 mole of CO2 is produced therefore for 0.4 mole of H2O 0.4 mole of CO2 is produced
now 0.4 mole of CO2 contain how much grams=0.4*44=17.6grams
but complete combustion of 2 mole of ethane produce 4 mole of CO2 and 6 moles of H2O
so for 6 mole of H2O 4 mole of CO2 is produced therefore for 0.4 moles of H2O 0.27 moles of CO2 is produced
Answer:
1 unit
Explanation:
It is expressed as a multiple of one-twelfth the mass of the carbon-12 atom, 1.992646547 × 10−23 gram, which is assigned an atomic mass of 12 units.
1/12 * 12 = 1. I think so.
There u go. the valence electrons can be no more than eight on the first ring and you only have 4
First, let's find the number of moles of ammonium nitrite.
0.5 mol/L * 1.10 L = 0.6 mol
The decomposition reaction is
NH₄NO₂ → N₂ + 2 H₂O
Let's calculate the amount of N₂ gas produced.
0.6 mol * 1 mol N₂/1 mol NH₄NO₂ = 0.6 mol N₂
Then, let's compute P through the ideal gas equation:
P = nRT/V
P = (0.6)(0.0821 L-atm/mol-K)(25+273 K)/10 L
P = 1.47 atm

I’m good with DNA hehehehe
