Answer: 0.04M
Explanation:
Tetraoxosulphate(VI) acid has a formula of H2SO4.
The concentration of the whole acid is 0.02M, and there are 2 hydrogens in the formula. That means we multiply 0.02M * 2, giving the answer of 0.04M.
Another visual explanation...
H2SO4 = H2(2+) + SO4(2-)
There are two hydrogens, the double amount of concentration of H2SO4, giving the answer of 0.04M.
Answer:Ethyne
Explanation:
Ethyne is more commonly known under the trivial name acetylene. It is the simplest of the alkynes, consisting of two carbon atoms connected by a triple bond, leaving each carbon able to bond to one hydrogen atom. Since both carbon atoms are linear in shape, all four atoms lie in a straight line.
Answer: The freezing point of 3.46 gram of a compound X in 160 gram of benzene is 
Explanation:
The relation of density and molar mass is:
where
d = density = 3.27 g/ L
P = pressure of the gas = 773 torr = 1.02 atm (760 torr = 1atm)
M = molar mass of the gas = ?
T = temperature of the gas = 
R = gas constant = 
The relation of depression in freezing point with molality:
= depression in freezing point = 
= 
= freezing point constant = 5.1
m = molality = 
Thus the freezing point of 3.46 gram of a compound X in 160 gram of benzene is
Don’t worry, you’re right :)
