Answer: 60.7 g of 
will be formed.
Explanation:
To calculate the moles :
The balanced chemical reaction is
is the limiting reagent as it limits the formation of product and 
is the excess reagent.
According to stoichiometry :
6 moles of produce = 4 moles of
Thus 2.68 moles of will produce=
of
Mass of 
Thus 60.7 g of will be formed by reactiong 60 L of hydrogen gas with an excess of
I did this question before and the answer is Magnesium and silicon, B.
Answer:
There are 
moles of bactoX present in a 3.0 μL sample volume that contains 7.512×106 bacterial cells
Explanation:
Given that:
The number of molecules present in one bacterial cell is 
molecules
and the sample contains 
molecules.
Number of moles = number of molecules /Avogadro's number
where;
Avogadro's number = 6.023 × 10²³
Number of moles = 
Number of moles = 
moles
So; moles is present in one bacteria cell
Similarly; the sample contains molecules.
Therefore; the number of moles present in the bactoX is = 
= moles
Channel proteins
Channel proteins are macromolecules that are embedded in plasma membranes of cells. Their function is to provide a pathway for molecules into and out of the cell, as the remaining parts of the membrane are impermeable. An example of such protein channels are those that are present to facilitate the diffusion of glucose.
