Answer:

thermal energy leads to an increase in the kinetic energy also increasing in temperature This is known because temperature is in fact the measure of the average kinetic energy of the molecules.

Chlorine can be prepared in the laboratory by the reaction of manganese dioxide with hydrochloric acid, HCl(aq) , as described b
Katyanochek1 [597]

Answer:

m_{MnO_2}=1.378gMnO_2

Explanation:

Hello,

In this case, we first apply the ideal gas equation to compute the moles of produced chlorine:

n_{Cl_2}=\frac{PV}{RT}=\frac{765 Torr*\frac{1atm}{760Torr}*0.385L}{0.082\frac{atm*L}{mol*K}*298.15K} =0.01585molCl_2

Then, by considering the given reaction, applying the stoichiometry, that shows a 1 to 1 relationship between chlorine and manganese dioxide, we find:

m_{MnO_2}=0.01585molCl_2*\frac{1molMnO_2}{1molCl_2} *\frac{86.937gMnO_2}{1molMnO_2} \\m_{MnO_2}=1.378gMnO_2

Best regards.

If a neutral atom has 22 protons within its nucleus, how many electrons will it have orbiting the nucleus?
astraxan [27]

Answer:

If a neutral atom has 22 protons inside its nucleus, it will have 22 electrons orbiting the nucleus.

Explanation:

An atom is the smallest amount of matter that undergoes chemical changes and is made up mainly of subatomic particles: electrons, protons and neutrons. The atomic nucleus is made up of protons, with a positive electric charge, and neutrons, which have no charge, while electrons, with a negative electric charge, revolve around the nucleus.

A neutral atom is one that lacks an electrical charge due to a trade-off between the number of its protons and electrons. In other words, although it has an electric charge, it is balanced between protons, electrons and neutrons. So in a neutral atom, the number of electrons equals the number of protons because the negative charge of the electrons is offset by the positive charge of the protons.

<u><em>If a neutral atom has 22 protons inside its nucleus, it will have 22 electrons orbiting the nucleus.</em></u>
