Usually with roman numerals, like iron (II) chromate
iron has a charge of 2
or manganese (IV) oxide, manganese has a charge of 4
(these are ionic compounds just to let you know)

Explanation:
The salts of carboxylate are named by the writing, which is also named as the creation of the first, which is followed by the name of the carboxylic acid were '-ic' of the acid end and replaced by the 'ate'.
Following are the description of the given reaction:
In reaction A:
2-Bromopropanoic acid= 
⇄ 
The IUPAC name is Sodium-2-Bromopropanate
In reaction B:

Answer:
Option (C) 1.30 moles
Explanation:
The following data were obtained from the question:
Volume (V) = 20L
Temperature (T) = 373K
Pressure (P) = 203 kPa
Gas constant (R) = 8.31 L.kPa/mol.K.
Number of mole (n) =...?
The number of mole of the gas in the container can obtained by applying the ideal gas equation as illustrated below:
PV = nRT
Divide both side by RT
n = PV /RT
n = 203 x 20 / 8.31 x 373
n = 1.30 mole.
Therefore, 1.30 mole of the gas is present in the container.
