Answer:
the true statement is... The pH of the weak acid will be higher than the pH of the strong acid
Explanation:
pH is a measured of the extent to which acids dissociate into ions when plced in aqueous solution.
Strong acid dissociate near-completely, and weak acids barely dissociate.
At equal concentrations, a strong acid will have a lower pH than a weak acid, since the strong one will donate more proton to the solution.
H=100
d=0.1
k=1000
so, the options become 25,250,250,250. hence answer is A
Answer:
9.31 g = 0.00931 kg
Explanation:
We need to tell that 9.31 gram is same as what. There are many units that measure the meass of an object like milligram, kilogram, centigram etc.
The relation between kilogram and gram is as follows :
1 kg = 1000 g
or
1 g = 0.001 kg
If we change 9.31 gram to kg, we get :
9.31 g = (9.31 × 0.001) kg
or
Hence, 9.31 g is the same mass as 0.00931 kg.
