Give the chemical symbol of an element in the third period (row) of the periodic table with four 3p electrons.
1 answer:
<u>Answer: </u>The chemical symbol of the element is Sulfur.
<u>Explanation:</u>
The element which is present in third period of the periodic table having four 3p electrons is Sulfur. Sulfur is the 16th element of the periodic table which has 6 valance electrons.
The electronic configuration of this element is:
This element is considered as a non-metal because it will accept electrons in order to attain stable electronic configuration.
Hence, the chemical symbol of the element is Sulfur.

Answer: 7.29 g of will be produced from the given masses of both reactants.
Explanation:
To calculate the moles :
According to stoichiometry :
1 mole of require = 8 moles of
Thus 0.0267 moles of will require=
of
Thus is the limiting reagent as it limits the formation of product and
is the excess reagent.
As 1 mole of give = 8 moles of
Thus 0.0267 moles of give =
of
Mass of
Thus 7.29 g of will be produced from the given masses of both reactants.
