Answer:
CaCl2 (aq) + K2CO3(aq) ---------> CaCO3(s) + 2KCl(aq)
Explanation:
We have the reactants as calcium chloride and potassium carbonate. Recall that we are expecting that the reaction will yield a precipitate. We must keep that in mind as we seek to write its balanced chemical reaction equation.
So we now have;
CaCl2 (aq) + K2CO3(aq) ---------> CaCO3(s) + 2KCl(aq)
Recall that the rule of balancing chemical reaction equation states that the number of atoms of each element on the right side of the reaction equation must be the same as the number of atoms of the same element on the left hand side of the reaction equation.
Answer:
the difference between k and l is that (k) is more soluble than (L) because the mass of 200 has lower grams than 100.
There is no energy available to transfer to the surroundings when bonds break as it's an endothermic reaction.
<h3>What is Endothermic reaction?</h3>
This is the type of reaction in which heat is absorbed from the surrounding and is involved in the breaking of bonds.
There is no energy available to transfer to the surroundings when bonds break because it's needed in the conversion of the reactant to product in a chemical reaction.

According to Avogadro constant 1 mole = 6.02 x 10^23 what about 9.25 x10 ^21
that is 1 mole x ( 9.25 x10 ^21) / (6.02 x10^23) = 0.0154 moles
Answer:
2Al + 6H2O --> 2Al(H2O)3 + 3H2
Explanation:
aAl + bH2O --> cAl(H2O)3 + dH2
To balance this equation, the Al(H2O)3 is first multiplied by c = 2 to even out the water molecule.
Since we have done that, the reactant water molecule is balenced with b = 3 so that the difference in the Hydrogen in the aluminum hydroxide molecule and the reactant water molecule, which is 6 goes to the H2 (d = 3) in the product.
Then, the Al metal is balanced with a = 2 and then the reaction is balanced.
2Al + 6H2O --> 2Al(H2O) + 3H2
