Consider these reactions:

Virty [35]

511.2 grams of chlorine gas consumed (with excess H-) when

1,342.0 kJ of energy is released from the system.

<h3></h3><h3>What is an exothermic reaction?</h3>

In thermochemistry, an exothermic reaction is a "reaction for which the overall standard enthalpy change ΔH⚬ is negative."

Given that 1 mole of chlorine releases -184.6 energy.

Then, we have to find the number of moles of chlorine when 1,342.0 kJ of energy is released from the system.

So, calculating number of moles of chlorine.

Moles = $\frac{-1,342.0 \;kJ}{-184.6\;kJ}$

Moles = 7.2 mole

Now, calculating number mass of chlorine.

$\rm Moles=\rm\frac{Mass}{Molar \;mass}$

Mass = 7.2 mole x 71 g/mole

Mass = 511.2 gram

Metals experience plastic deformation when _____.

xxTIMURxx [149]

Metals experience plastic deformation when a specific amount of pressure and temperature is applied to them. Most metals have low specific heat. Because of their low specific heat, they easily get hot when heat is applied to them.
