<u>Answer:</u> The chemical reaction for the synthesis reaction is given below.
<u>Explanation:</u>
Synthesis reaction is defined as a chemical reaction in which two small chemical substances combine together to form a single compound. The general equation for this chemical reaction follows:
For the reaction of calcium and oxygen combining together to form calcium oxide, the equation follows:
By Stoichiometry,
2 moles of calcium element combines together with 1 mole of oxygen gas to produce 2 moles of calcium oxide.
Hence, the chemical equation for the reaction is given above.

Answer: 
molecules of 
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number 
of particles.
To calculate the moles, we use the equation:
1 mole of contains = molecules
0.128 mole of contains = 
molecules
Thus there are molecules of
Answer:
Ionic compounds are neutral compounds made up of positively charged ions called cations and negatively charged ions called anions.
Explanation:
For binary ionic compounds (ionic compounds that contain only two types of elements), the compounds are named by writing the name of the cation first followed by the name of the anion.
I believe it's B: series circuit
good luck
