The mass of gas in the tank has been 222 g. Thus, option B is correct.
The volume occupied by 1 mole of gas at standard temperature and pressure has been 22.4 L.
<h3>Computation for the Mass of gas</h3>
The volume of gas in the tank has been given as 170 L.
The moles of gas in the tank has been:
![\rm 22.4\;L=1\;mol\\\\ 170\;L=\dfrac{1}{22.4}\;\times\;170\;mol\\\\ 170\;L=7.58\;mol](https://tex.z-dn.net/?f=%5Crm%2022.4%5C%3BL%3D1%5C%3Bmol%5C%5C%5C%5C%0A170%5C%3BL%3D%5Cdfrac%7B1%7D%7B22.4%7D%5C%3B%5Ctimes%5C%3B170%5C%3Bmol%5C%5C%5C%5C%0A%20170%5C%3BL%3D7.58%5C%3Bmol)
The moles of gas in the tank has been 7.58 mol.
The molar mass of the gas has been 32.0 g/mol.
The mass of gas has been calculated as:
![\rm Mass=Moles\;\times\;Molar\;mass\\ Mass=7.58\;\times\;32\;g\\ Mass=242\;g\\ Mass\approx 222\;g](https://tex.z-dn.net/?f=%5Crm%20Mass%3DMoles%5C%3B%5Ctimes%5C%3BMolar%5C%3Bmass%5C%5C%0AMass%3D7.58%5C%3B%5Ctimes%5C%3B32%5C%3Bg%5C%5C%0AMass%3D242%5C%3Bg%5C%5C%0AMass%5Capprox%20222%5C%3Bg)
Thus, the mass of gas in the tank has been 222 g. Thus, option B is correct.

They are all true so all the above
Answer:
<em><u>Hydrochloric acid and sodium hydroxide interact, resulting in salt and a release of heat. As we can see, the result of the interaction of two highly aggressive compounds is table salt and water – compounds that are ultimately harmless, even beneficial, to human beings.</u></em>
<em><u>2</u></em><em><u>)</u></em><em><u> </u></em><em><u>An acid is a substance that donates protons (in the Brønsted-Lowry definition) or accepts a pair of valence electrons to form a bond (in the Lewis definition). A base is a substance that can accept protons or donate a pair of valence electrons to form a bond.</u></em><em><u>A base is a substance that can accept protons or donate a pair of valence electrons to form a bond. Bases can be thought of as the chemical opposite of acids. A reaction between an acid and base is called a neutralization reaction.</u></em>

Answer:
Number 4 is an example of a chemical reaction
Explanation:
heThe chalk is reacting with the vingear which is creating a new substance. The new substance is the gas that the reaction gives off.
<span>If liquid water is exposed to normal atmospheric pressure, then it is exposed to constant pressure which means to change its state of matter the temperature of the system should be changed. Increasing the temperature will cause an increase in the kinetic energy of the molecules which will change its state to gas.</span>
