Mass of solute = 25.8 g
mass solution = 212 g
% =( mass of solute / mass solution ) x 100
% = ( 25.8 / 212 ) x 100
% = 0.122 x 100
= 12.2 %
Concentrated sulfuric acid is used to promote acid catalyzed dehydration because it has little water.This favor the forward reaction.sulfuric acid acts as as proton source to enable loss of leaving group in forward reaction and electrophile addition in reverse reaction.
Answer: A
Explanation:
A contour interval is a vertical distance or difference in elevation between contour lines. Index contours are bold or thicker lines that appear at every fifth contour line.
<span>Sulfuric acid has the highest production levels of any chemical in both the US and the world. The US alone creates 37 million tons a year. It has many uses, but one of the largest is as fertilizer.</span>
AXz
Explanation:
It is a chemical notation of nuclide
Here X is the symbol of the element
A is the mass number of element
A=n+p(sum of protons and neutrons)
Z is the atomic number.
For example, 12C6
Hers X is C, symbol of carbon
12 is the mass number and 6 is the atomic number of the carbon.
