Answer:
Explanation:
You must convert the 6.00 grams of H₂ into number of moles, and then use the stoichiometry of the reaction to find the number of moles of NH₃, which can be converted into volume using the ideal gas equation.
<u></u>
<u>1. Number of moles of H</u><u>₂</u>
- number of moles = mass in grams / molar mass
- molar mass of H₂ = 2.016g/mol
- number of moles = 6.00grams / 2.016g/mol = 2.97619mol
<u></u>
<u>2. Number of moles of NH</u><u>₃</u>
<u></u>
i) Chemical equation:
ii) Mole ratio:
iii) Proportion:
- x mol NH₃ / 2.97619mol H₂ = 3 mol NH₃ / 2 mol H₂
<u>3. Volume of NH₃</u>
- V = 4.4642857mol × 0.08206 atm·liter/(K·mol) × 506K / 2.05atm
Answer:
A
Explanation:
because the species being oxidized shares electrons with the species that is reduced.making the oxidized element positively charged and the reduced element negatively charged.
I hope this helps
<span>I think it is a but dont take me for it. I searched it and thats what I found since liquid in beaker B is more dense then realtivley speaking the object is less dense compared other liquid and floats at a higher level.</span>
If 4 moles of P is used by 5 mole of O2
then....0.489 moles will be used by 5/4 × .489 = .611 moles of O2
so .611 moles
so if 4 moles of P is burnt , 1 mole of P4O10 is produced ....so for .489 moles...... .489/4=.122 moles !
so mass will be .122× 283.89 = 34.7 grams
so first ans is .611 moles and second is 34.7 grams !
if you have any problem regarding this , just comment !!!
CO2 is the emperical formula of carbon dioxide
