Answer:
a. Copper (II) oxide is the limiting reactant.
b.
c.
d.
Explanation:
Hello,
In this case, for the given reaction:
a. The limiting reactant is identified by computing the available moles of ammonia and the moles of ammonia that react with 45.2 g of copper (I) oxide as shown below:
In such a way, as there more ammonia available than that is reacted, we say it is in excess and the copper (II) oxide the limiting reactant.
b. Here, with the reacting moles of ammonia, we compute the yielded grams of nitrogen:
c. Now, since the 5.30 g of nitrogen are the expected grams of it, the percent yield of nitrogen is compute by dividing the real obtained mass over the theoretical previously computed mass:
d. Finally, as 0.532 moles of ammonia are available, but just 0.379 moles react, the unreacted moles are:
That in grams are:

Answer is: a. The storm damaged the air conditioner.
Because air conditioner is outside, storm could damage it.
There is not enough information that the make and model of the air conditioning unit is not compatible for his house, that David has been using his air conditioner too much or the air conditioner was vandalized.
A covalent bond occurs when two atoms share one pair of valence electrons
Brainliest answer please? :)
CH3OH IS MOLECULES OF ALCOHOL
The answer for the first question is A. Proton is the subatomic particles which adds most of the mass of an atom as well as the neutron since they have the same mass. Photon, on the other hand, is not one of the subatomic particles.
