Answer : There are 7.0 moles of oxygen in the formula.
Explanation :
The chemical formula of nickel tetracarbonyl is Ni(CO)₄.
We can see that there are 4 carbon atoms and 4 oxygen atoms which together form 4 carbonyl (CO) groups.
Therefore the mole ratio of C to O is 1 : 1.
Let us use this as a conversion factor to find moles of oxygen.
We have 7.0 moles of carbon in the formula.
The moles of O can be calculated as,
There are 7.0 moles of oxygen in the formula.

Answer:
B. Decreasing the pressure applied to the gas molecules
Explanation:
According to Boyle's Law, the pressure of the gas is inversely proportional to the volume of the gas. So, the option B is correctly implied to it.
Other values such as Temperature, Number of molecules are inversely proportional to the volume of the gas.
Size of the gas molecules is negligible as compared to volume.

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.
