Answer:
0.156mol
Explanation:
Number of moles of a substance can be calculated from its mass by dividing its mass by molar mass i.e.
Number of moles (n) = mass/molar mass
Molar mass of PbCl4 is as follows, where Pb = 207.2g/mol, Cl = 35.5g/lol
PbCl4 = 207.2 + 35.5(4)
= 207.2 + 142
= 349.2g/mol
Using: mole = mass/molar mass
mole = 54.32 grams ÷ 349.2g/mol
mole = 0.1555
mole = 0.156mol
Answer:
A conjugate acid, within the Brønsted–Lowry acid–base theory, is a chemical compound formed when an acid donates a proton to a base—in other words, it is a base with a hydrogen ion added to it, as in the reverse reaction it loses a hydrogen ion
Explanation:
Answer:
The correct answer is option A.
Explanation:

Reducing the partial pressure of chlorine gas means that removal of chlorine gas from the equilibrium will shift the equilibrium in the direction according to Le Chatelier's principle.
On a removal of product from the equilibrium shifts the reaction in the forward reaction for reestablishment.So, when the partial pressure of chlorine is reduced by 50% the equilibrium will shift in forward direction in which
will be consumed to form more chlorine gas.
Hence, A is correct .
