<u>mass of reactants = mass of products</u> best represents the law of conservation of mass

Explanation:

This is a law of thermodynamic that applies to chemical reactions. The mass of the reactants must equal to that of the products because energy/mass cannot be destroyed or created. This is why ideally, chemical reactions should be balanced to conform to this law.

A 20. 0-liter flask contains a mixture of argon at 0. 72 atmosphere and oxygen at 1. 65 atmospheres. What is the total pressure
exis [7]

The total pressure of the system is equivalent to the sum of all the pressure of the individual gases. The total pressure of the flask is 2.37 atm.

<h3>What is total pressure?</h3>

According to Dalton's law, the total pressure of the system will be equivalent to the total of the pressures exerted by the individual gases present in the system.

The total pressure of gases is given as,

\rm P = P_{1} +P_{2}+ P_{3}.....P_{n}

Given,

  • The pressure of argon gas = 0.72 atm
  • The pressure of oxygen = 1.65 atm
  • Total pressure = P

Substituting values in the above equation:

\begin{aligned}\rm P &= 0.72 + 1.65\\\\&=2.37\;\rm atm\end{aligned}

Therefore, 2.37 atm is the total pressure of the flask.
