Answer:
18
Explanation:
You add the two numbers on the bottom left (8 and 32) and then subtract the number On the bottom middle right (22) from it (40-22=18) and then the answer to that gives you the answer of how much water is produced.
hope that helped :)
There are three possible Isomers for Molecular Formula C₃H₄. Isomers are;
1) Propyne 2) Propa-1,2-diene 3) CyclopropeneStructures of all three isomers are given below.
There are no geometrical isomers for given molecular formula because geometrical isomers are formed in compounds containing double bond with at least two bulky groups at both sp² hybridized carbons. In given isomers, propyne does not contain any double bond, Propa-1,2-diene is symmetrical in nature while cyclopropene is a 3-membered ring. And for cycloalkenes there must be other groups attached to ring other than Hydrogen atom, hence cyclopropene does not contain any other group, so it can not show geometrical isomerism.
Answer:
Final pressure = 362.7 Pa
Explanation:
Given that,
Initial volume, V₁ = 930 ml
Initial pressure P₁ = 156 Pa
Final volume, V₂ = 400 mL
We need to find the final pressure. We know that the relation between volume and pressure is inverse i.e.

So, the final pressure is equal to 362.7 Pa.

So molarity which is represented by that 0.01M refers to the amount of moles that is present in 1L or 1dm³ of the substance, in this case the acid. Molarity refers to CONCENTRATION therefore and has little to do with the strength of the acid (the strength is dependent on the pH).
Thus your answer is OPTION B
