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

What is the change in air pressure over a given distance called? wind speed air pressure force factor air pressure gradient

lubasha [3.4K]

The change in pressure over a given distance is defined as a pressure gradient. The strength of this pressure gradient determines how fast the wind moves from higher pressure toward lower pressure. A stronger pressure gradient will cause stronger winds, as shown in Figure 2. >> Balanced in the vertical by the force of gravity
