<u>Answer:</u> The total number of electrons that must be shared between carbon and oxygen atoms are 8.
<u>Explanation:</u>
A covalent compound is formed when sharing of electrons takes place between the atoms forming a compound.
Carbon is the 6th element of the periodic table having electronic configuration of 
This element requires 4 electrons to complete its shell.
Oxygen is the 8th element of the periodic table having electronic configuration of 
This element requires 2 electrons to complete its shell.
So, in order to complete the octet of both the elements, 2 oxygen atoms are required for 1 carbon atom.
Hence, the total number of electrons that must be shared between carbon and oxygen atoms are 8.
Answer:
Yes, the formed product is calcium nitride,
.
Explanation:
Hello,
In this case, the answer is yes, since nitrogen in gaseous state is able to react with calcium in solid state to form calcium nitride as shown below:

This is possible since calcium losses two electrons and nitrogen gains three electrons to remain positively and negatively charged respectively, forming the aforementioned ionic compound.
Best regards.
Atomic mass is the number that you get when the protons and neutrons in the nucleus are added together atomic number is the number of protons in the nucleus
Answer:
144 g
Explanation:
Use the mole ratio of 4 mol CO2 for every 9 mol O2 to convert from mol O2 to mol CO2. Then use the molar mass of CO2 to convert from mol of CO2 to grams of CO2.
7.34 mol O2 • (4 mol CO2 / 9 mol O2) • (44.01 g CO2 / 1 mol CO2) = 144 g CO2
