A compound with the empirical formula, ch2, has a molar mass equal to 84.2 g/mol. what is the molecular formula for the compound
MatroZZZ [7]
<span>Mass of CH2 = 12 + 2 = 14 g/mol The number of CH2s there are. So since the total mass is 84.2 g/mol. The solution is 84.2/14 = 6.012 thus the answer is 6 There are 6(CH2) So the molecular formula is C6H12</span>

The electron configuration that belongs to the atom with the lowest first ionization energy is?
sasho [114]

The electron configuration that belongs to the atom with the lowest first ionization energy is francium.

<h3>What is ionization energy? </h3>

Ionization energy is defined as the minimum amount of energy required to remove the most loosely electron present in outermost shell.

<h3>Ionization energy across period</h3>

Ionization energy increase as we move from left to right in the period. This can be explained as when we move from left to right along period new electron is added to the same shell which increase the nuclear charge. Hence results int he decrease in size. Due to this decrease in size more energy is required to remove electron from outermost shell.

<h3>Ionization energy along group</h3>

Ionization energy decrease as we move from top to bottom along group. This can be explained as we move from top to bottom new electron is added to new shell. Due to addition of new shell the size of atom increases which results in the decrease in the nuclear charge. Due to this less amount of energy is needed to remove an electron.

Thus, we concluded that the electron configuration that belongs to the atom with the lowest first ionization energy is francium.

How do muscles work in pairs to make parts of the body move?
schepotkina [342]

Answer:

Muscles work in pairs to move a bone.

Skeletal muscles only PULL in one direction. For this reason they always come in pairs. When one muscle in a pair contracts, to bend a joint for example, its counterpart then contracts and pulls in the opposite direction to straighten the joint out again.
