Answer:

Explanation:
Hello,
In this case, by considering the given seminormal solution, we infer it is a 0.5-N solution which means that we can obtain the equivalent grams as shown below for the 55 cc (0.055 L) volume:

Next, since sodium carbonate has two sodium ions with a +1 oxidation state each, we can obtain the moles:

Finally, the mass is computed by using its molar mass (106 g/mol)

Regards.
Answer:
Six electrons.
Explanation:
A carbon atom has six protons, so it must have six electrons.

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
