2Al + 3CuCl2 ➡ 2AlCl3 + 3Cu.
Moles of Al = 1.2/27 = 0.045 moles
2 moles of Al reacts with 3 moles of CuCl2.
Therefore, 1 mole of CuCl2 reacts with =2/3 x moles of Al
= 2/3 x 0.045
= 0.03 moles.
Answer:
The half-life of reactants in a nuclear decay reaction remains constant over time, but the mass of reactants that are consumed decreases.
Explanation:
The half-life is defined as the time in which half of the starting number of radioactive atoms decayed in products. The half-life it is a intrinsec property of the reactant atom and it is a constant. As time passes more and more atoms are decaying through the nuclear reaction so the quantity of the radioactive compounds (reactant) is decreasing.
Answer:0.00000009
Explanation:
9.11 × （1/1000000000）=0.00000009
Answer:
an ionic equation is a chemical equation in which the electrolytes in aqueous solution are expressed as dissociated ions. ... Additionally, the net charge is the same on both sides of the equation.
Explanation:
So what you end up with is you always end up H+ plus OH- yields H2O, because HCl, and NaOH, since they're strong, they fully dissociate. So the Na+, and the Cl - are spectator ions. So with a strong acid and strong base, the net ion equation is always H+ plus OH- yields H2O.
