Answer:
True.
Explanation:
When copper and nitrogen combine they formed the bond which is called ionic bond.
Ionic bond:
It is the bond which is formed by the transfer of electron from one atom to the atom of another element.
Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.
For example:
The electronegativity of nitrogen is 3.04 and that of copper is 1.9. Nitrogen required three electrons to complete the octet while copper loses its one valance electron to complete the octet. Thus when both combine nitrogen atom accept three electrons from three atoms of copper and form ionic bond. The compound formed is called copper nitride.

The
balanced reaction would be written as:
<span>
C7H6O3 + C4H6O3--->C9H8O4 + HC2H3O2
To determine the percent yield, we need to first
determine the theoretical yield if the reaction were to proceed completely.
Then, we divide the actual yield that is given to the theoretical yield times
100 percent. The limiting reactant from the reaction would be salicylic acid.
We do as follows:
<span>Theoretical yield: 50.05 g C7H6O3 ( 1 mol /
138.21 g ) ( 1 mol C9H8O4 / 1 mol C7H6O3 ) ( 180.157 g / mol ) = 65.24 g C9H8O4 should be produced
Percent yield = 55.45 / 65.24 x 100 = 84.99%
<span>
Therefore, the percent yield for the given amount of salicylic acid is 84.99%

The number of H atoms in 3(NH₄)₂CrO₄ = 24
<h3>Further explanation </h3>
The empirical formula is the smallest comparison of atoms of compound forming elements.
A molecular formula is a formula that shows the number of atomic elements that make up a compound.
(empirical formula) n = molecular formula
Subscripts in the chemical formula indicate the number of atoms
The compound of 3(NH₄)₂CrO₄ ( 3 molecules of (NH₄)₂CrO₄ ) :
Number of H :
93,000 in scientific notation is fairly simple, you're just breaking down the number a tad so you don't have to use a huge number!
BUT! In scientific notation 93,000 is 9.3x10^4 - written out that's nine point three times ten to the fourth power! (:
I hope all is well, and you pass! Good luck, rockstar! (: If you have any follow up questions, or even any comments - pm me or just let me know!
