Hey there!
1 mole has 6.022 x 10²³ atoms.
Multiply that by 3.2 because we have 3.2 moles.
3.2 x 6.022 x 10²³
1.9 x 10²⁴
There are 1.9 x 10²⁴ atoms in 3.2 moles of chromium.
Hope this helps!
1) Chemical reaction: CH₄ + H₂O → 3H₂ + CO ΔH = + 206 kJ/mol.
2) Chemical reaction: CO + H₂O → CO₂ + H₂, ΔH = + 2,8 kJ/mol.
3) Chemical reaction: CH₄ + 2O₂ → CO₂ + 2H₂O ΔH = -802 kJ/mol.
4) Chemical reaction: 2H₂ + O₂ → 2H₂O ΔH = 2·(-242 kJ7mol) = - 484 kJ/mol.
Endothermic reaction (ΔH>o) and exothermic reaction (ΔH<span><0).</span>
The answer is (1) natural transmutation. When Co-60 undergoes beta decay (be it beta positive or beta negative), the product is another element (Fe or Ni). Transmutation is when an element turns into another element via a nuclear process. Since this occurs without the aid of another agent that causes the nuclear change (e.g. a neutron source), it is natural transmutation.
Answer:
Oil is non-polar
Explanation:
-it consists of non-polar bonds which connect atoms having similar electro negativities
