The molecules in system #2 have a higher kinetic energy because they are at a higher temperature than molecules in system#1.

<h3>Heating of water molecules</h3>

Temperature is defined as a measure of the average kinetic energy of the molecules of a body. The higher the temperature of a body, the higher the kinetic energy of the molecules of the body.

In both systems, we have water molecules that have the same formula H2O. However, the molecules in system #2 have a higher kinetic energy because they are at a higher temperature than molecules in system#1.

Which gas will diffuse at a faster rate, CH4 with a molar mass of 16 g or
vivado [14]

Answer:

CH₄ will diffuse at faster rate.

Explanation:

According to Graham's law,

The rate of diffusion is inversely proportional to the square root of molar mas of gas.

It  is given in question the molar mass of CH₄ is 16 g. Thus the square rot of 16 is.

√16 = 4

The molar mass of SO₂ is 64 g and the square root is,

√64 = 16

As it is stated that diffusion rate is inversely related to the square root of molar mass thus the diffusion rate of  SO₂ is lower while methane diffuse faster.

How many single covalent bonds could an element with the electron
Tcecarenko [31]

Answer:

1

Explanation:

I would say 1 because that configuration has 7 valence electrons.  The goal of the atom is to gain a full octet so it just needs to gain 1 more electron to get the full octet.  To get the one electron to fill the valence shell it would only need to have 1 covalent bond.

I hope this helps.  Let me know if anything is unclear.

What volume is occupied by 2.719 x 1013 moles of methane gas, CH4?
slamgirl [31]

Answer:

6.5256×10¹⁴

Explanation:

n= v/24

v= n×25

v= 2.719×10¹³ × 24= 6.5256×10¹⁴ moles/dm³
