Answer : The balanced chemical reaction will be:
Explanation :
Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.
When solid zinc metal reacts with sulfuric acid to then it forms hydrogen gas and an aqueous solution of zinc (II) sulfate as a product.
This reaction is a single displacement reaction in which more reactive metal displaces least reaction metal from its solution.
The balanced chemical reaction will be:
Answer:
The chlorine atom, which starts with seven valence electrons, gains a single electron and becomes a negatively charged chlorine ion: Cl-. This ion has the same electron configuration as the noble gas argon, and therefore this ion is chemically stable too.
Answer:
Forming acids and alkalis. Soluble metal oxides (or metal hydroxides) produce alkaline solutions. Soluble non-metal oxides produce acidic solutions. Insoluble oxides will not affect the pH of water.
Explanation:
Q unknown = -Q H2O
Q H2O= (100g x 4.18 J/g C x (25C - 20C)
Q H2O = 2090J
-2090J = (50g x c x (25C-90C)
-2090J = -3250c
.64 = c
I am a high school student and have done this problem a few months ago for my test, hope this helps
