Answer:
CO
Explanation:
Elements will only one capital letter, that may/may not have a lower case letter after it. CO has a capital letter followed by another capital, so it's a compound
If another proton gets added to the molecule there will be an increase in the atomic number and atomic mass by 1 unit and a new species will form.
here boron is taken which has an atomic number of 5 and atomic mass of 11 so when we add a proton to it, it will change into carbon having atomic number as 6 and atomic mass as 12.

The new species formed will be
.
Answer:

Explanation:
Hello,
In this case, the undergoing chemical reaction is:

Thus, given the 1.00-kg of 12.5% ore, we can compute the theoretical yield of copper (II) oxide via stoichiometry:

Whereas the third factor accounts for the percent purity of the covellite. Then, given the percent yield, we can compute the actual yield by:

Regards.
Atoms of Carbon along with hydrogen bonded to the carbons in the molecule are 2 main elements for the molecule to be organic.
