1) H2O is able to dissolve both polar molecules and non polar ones
2) due to its extreme polarity it can even dissolve some I onic compounds
3 the h2o molecule itself is small in size
The correct answer is a Forward reaction to slow.
According to Le Chatelier's principle as the reactant decrease so the reaction should go leftward and this is called backward or reverse reaction so the reverse reaction will be fast to achieve equilibrium and the forward reaction will be slow.
The relative atomic mass of x is 101 u.
Molar mass is calculated by adding the atomic mass of all the elements in a compound.
Molar mass of x(HCO₃) =162 g/mol
Atomic mass of H = 1 g/mol
Atomic mass of C =12 g/mol
Atomic mass of O = 16 g/mol
Therefore, molar mass of x(HCO₃) will be
= x + 1 + 12 + 3 x 16
We know that:
x + 1 + 12 + 3 x 16=162
x + 61 = 162
x = 101 g/mol
The relative atomic mass of x will be 101 u.
