Hello.
In this case since sodium is a soft brilliant metal and chlorine is a green gas at normal conditions, they have totally different properties. Thus, since sodium chloride is also known as the table salt which is present as white crystals we can infer that the compound does not have the same properties, therefore it is false.

There are 0.31 mol in h3po4
Answer:
Explanation:
Molar mass of As2S3= {75(2) + 32(3)}
= 150 + 96 = 246g/mol
Amount = 3.25mole
And
Amount = mass/ molar mass
mass = amount × molar mass
Mass = 3.25 × 246
mass = 799.5g
