<h3>Answer:</h3>

1.46 moles

<h3>Explanation:</h3>

<u>We are given</u> ;

Mass of phosphorus trichloride is 200 g

We are required to calculate the number of moles of phosphorus trichloride;

We know that to calculate the number of moles we divide mass by the molar mass.

That is;

Moles = Mass ÷ Molar mass

Molar mass of phosphorus trichloride = 137.33 g/mol

Therefore;

Moles = 200 g ÷ 137.33 g/mol

= 1.456 moles

= 1.46 moles

Therefore, the moles of phosphorus trichloride are 1.46 moles

Substance A has a heat capacity that is much greater than that of substance B. If 10.0 g of substance A initially at 30.0 ∘C is

astra-53 [7]

Explanation:

In a heat exchange, the temperature change is inversely proportional to the specific heat capacity. Since substance A has a heat capacity that is much greater than that of substance B, the temperature change of substance A will be less than the temperature change of substance B. Therefore, the final temperature is closer to that of $30^\circ C$ than $80^\circ C$ .
