Which of the following elements will sulfur most readily react with in order to help it fill its outer shell with 8 electrons?

Chemistry
1 answer:
Gelneren [198K]3 years ago
5 0

Answer:

Magnesium

Explanation:

Using the KLMN styled electronic configuration, the electronic configuration of sulphur with atomic number 16 is 2, 8,6

What this means is that it needs extra 2 electrons to fill into its M shell to attain the octet configuration.

Now let’s look at Magnesium, with atomic number 12, the electronic configuration it has is 2,8,2.

This means it has 2 extra electrons to give away so as to attain its own stability.

The sulphur atom will gladly accept the two electrons which the magnesium atom wants to give away. This makes it the perfect element to be reacted with sulphur to make it attain its octet configuration

A sample of 3.62 moles of diphosphorous trioxide is
Sindrei [870]

H_3PO_32H_3PO_32H_3PO_3P_2O_3Answer:

B

Explanation:

This question is about stoichiometry. From the balanced equation P_2O_3 + 3H_2O⇒2H_3PO_3, we see that 3 moles of water is needed to react with 1 mole of P_2O_3.

This means that, to fully react 3.62 moles of P_2O_3, we would need 3*3.62 or  10.86 moles of water. However, we only have 6.31 moles, so water is the limiting reactant.

Since 3 moles of water react with 1 mole of P_2O_3, 6.31 moles of water can fully react with 6.31÷3 or 2.1033 moles of P_2O_3.

From the balanced equation, we see that every mole of P_2O_3 reacted gets you 2 moles of 2H_3PO_3. Therefore, 2.1033 moles of P_2O_3 would give you approximately 4.21 moles of H_3PO_3.
