<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.
Carbon monoxide (CO) is the name
Answer: Between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.
Answer:
When a sodium atom transfers an electron to a chlorine atom, forming a sodium cation (Na+) and a chloride anion (Cl-), both ions have complete valence shells, and are energetically more stable. The reaction is extremely exothermic, producing a bright yellow light and a great deal of heat energy.
Answer:
2NH3 - Gas Phase
2 NaCl - Solid Phase
2KNO3+PBI2 - Aqueous Phase
Explanation:
2NH3 is ammonia gas which is colorless and has a bad pungent smell.
NaCl is salt. It has crystalline structure and can exhibit both aqueous or a liquid phase. Since there is no H2O molecule in the formula of NaCl, hence it is not aqueous. It is not liquid as well because liquid NaCl is represented as NaCl (l) while aqueous NaCl is represented as NaCl (aq).
The reaction 2KNO3+PBI2 will take place in aqueous phase and hence these two exists in aqueous phase
