Answer:
The new molarity is 0,96 M.
Explanation:
A dilution consists of the decrease of concentration of a substance in a solution (the higher the volume of the solvent, the lower the concentration).
We use the formula for dilutions:
C1 x V1 = C2 x V2
2,4 M x 100ml = C2 x 250 ml
C2= (2,4 M x 100ml)/250 ml
<em>C2= 0,96 M</em>
The correct answer of the given question above would be option C. Carbon dioxide absorbs the most heat energy during sublimation. It is the<span> transition of a substance directly from the solid to the gas phase without passing through the intermediate liquid phase. Hope this answers your question.</span>
Answer:
According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs. Hence, the correct statement is arrhenius acid produces hydrogen ions in solution.
<u>Answer:</u> The molarity of calcium hydroxide in the solution is 0.1 M
<u>Explanation:</u>
To calculate the concentration of base, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is 
are the n-factor, molarity and volume of base which is 
We are given:
Putting values in above equation, we get:
Hence, the molarity of in the solution is 0.1 M.
