Explanation:

In periodic table:

  • Elements are arranged according to their atomic number in increasing order.
  • When we move left to right we move along a period.The period in the periodic table tell us about the principal quantum number,(n).
  • When move from top to bottom we are moving in group. The group in the periodic table tell us about the number of the valence electrons present in the valence shell of the elements of the particular group.

Given a balanced chemical equation below: 3Cu(s) + 2H3PO4 --- > Cu3(PO4)2 + 3H2 How many moles of copper are needed to react
Harman [31]

Answer:

7.5 moles

Explanation:

We'll begin by writing the balanced equation for the reaction. This is given below:

3Cu + 2H3PO4 —> Cu3(PO4)2 + 3H2

From the balanced equation above,

3 moles of Cu reacted with 2 moles of H3PO4.

Therefore, Xmol of Cu will react with 5 moles of H3PO4 i.e

Xmol of Cu = (3 x 5)/2

Xmol of Cu = 7.5 moles

Therefore, 7.5 moles of Cu are needed to react with 5 moles of H3PO4.
