Answer is (b)
2,3,1 is the stoichiometry
The values in front of the elements are the stoichiometric values
(Since Al2Br6 has no value in front, it's considered 1)
Answer:
A stronger acid is needed to neutralize the reaction.
Explanation:
Neutral pH solutions are because the acid counteracts the effect of the base, and vice versa.
Both chemical products, both acid and base, reach a pH of 7, which indicates the neutrality of the solution in the reaction, that is, the solution is neither acidic nor basic but NEUTRAL.
The higher the alkalinity of the base, the greater the acidity of the acid will be needed to balance and balance the pH to give neutrality as the final product.
Answer:
(B) SECONDARY ALKYL HALIDE
A. force of gravity, since if an objects buoyancy force is more than the force of gravity you float.
Answer:
2KClO3(s) + heat → 2KCl(s) + 3O2(g)
Explanation:
KClO3(s) + heat → KCl(s) + O2(g)
Adding coefficients so that there are 6 O atoms on both sides.
2KClO3(s) + heat → KCl(s) + 3O2(g)
Balancing K and Cl atoms, there are 2 of each on the left and 1 of each on the right.
2KClO3(s) + heat → 2KCl(s) + 3O2(g)
The equation is now balanced.
