To solve this we use the equation,

 

M1V1 = M2V2

 

where M1 is the concentration of the stock solution, V1 is the volume of the stock solution, M2 is the concentration of the new solution and V2 is its volume.

 

.675 M x V1 = .25 M x 1.3 L

V1 = 0.48 L or 480 mL

18. Use the activity series to predict whether the following synthesis reaction will occur. Write the chemical equations for the
MAXImum [283]

<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:

A+B\rightarrow AB

For the reaction of calcium and oxygen combining together to form calcium oxide, the equation follows:

2Ca(s)+O_2(g)\rightarrow 2CaO(s)

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.
