2N2 + 3O2 ---> 2NO + 2NO2
You should do it based on moles and not grams.
1.14 g O = 0.071 moles O
1 g N = 0.071 moles N
So in NO2 you need 2 moles O for each mole of N
1 g N = 0.071 moles, so you need 0.071 x 2 moles of O = 0.0.142 moles O
0.142 moles O x 16 g/mol = 2.27 grams of O. So, you are actually correct because your answer is 2.28 grams. I just prefer to work it out in moles so it makes perfect chemical sense.
Answer:
the pressure is to tight needs to be looser 13.2L of 2.36 and 2.13L
Answer:
/D/ either absorbs or releases energy
Explanation:
During a phase change energy is either absorbed or released.
A phase change is a reversible process which occurs when a substance changes is its state from one form to another.
Phase changes are used to delineate physical changes.
- A phase diagram provides a graphic representation of the change.
- The diagram can be 2 dimensional or 3 dimensional.
When you pass around the side dishes at this year's Thanksgiving feast, here's one thing to be thankful for: you're eating mashed potatoes instead of mashed paper towels. But if you were chewing on the towels instead of the spuds, would you even know it.
Answer:
It is a reactant that produces smaller amount of product.
Explanation:
" The limiting reactant is a reactant that control the amount of product in chemical reaction because of its smaller amount"
Consider the example:
2 H₂ + O₂ → 2H₂O
two moles of hydrogen react with one moles of oxygen and produces two moles of water. when we take two mole of hydrogen and two mole of oxygen than again two mole of water is produced because hydrogen is limiting reactant and one mole of oxygen left un reacted.
Identification of limiting reactant:
Calculate the number of moles of reactant.
compare it with number of moles of product with help of balance chemical equation.
identify the reactant which produces less number of moles of product.
