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:
it remains the same
Explanation:
mass is like name is not changed any where mass express the amount of matter in an object which is fixed any where regardless its gravity
Answer:
116 Cal
Explanation:
15 g CHO × 4 Cal/g = 60 Cal
5 g PRO × 4 Cal/g = 20
4 g fat × 9 Cal/g = <u> 36 </u>
TOTAL = 116 Cal
There are 116 Cal in one serving of the product.
Answer:
Wood consists mainly of organic substances (99% of the total mass). Elemental chemical composition of wood of different breeds is practically the same. Absolutely dry wood on average contains 49% of carbon, 44% of oxygen, 6% of hydrogen, 0.1-0.3% of nitrogen. When burning wood remains its inorganic part - ash.
So the answer is flammability because wood is flammable.
