Answer:
Explanation:
1)
H₂SO₄:
Element (symbol) No of atoms in No of compounds Total atoms
1 molecule coefficient
H 2 1 2
S 1 1
O 4 4
2)
2H₃PO₄:
Element (symbol) No of atoms in No of compounds Total atoms
1 molecule coefficient
H 3 2 6
P 1 2
O 4 8
There are two mole of H₃PO₄. One mole contain 3 hydrogen atom, 1 phosphorus atom and 4 oxygen atoms. Thus in two mole of compound 6 hydrogen atoms, 2 phosphorus atom and 8 oxygen atoms are present.
Answer:Explanation: Polarity in a molecule arises due to unequal sharing of electrons. Hydrogen atom has one electron whereas chlorine atom has 17 electrons. Thus, in order to complete their octet both H and Cl will share an electron with each other.
Explanation:
Sir James Chadwick was the scientist who discovered the neutron. The electron and proton had already been found but with the neutron known, we knew everything that made up our universe. He won the 1935 Nobel Peace Prize for his discovery.
