Answer:
Acid: HCl(aq), conjugate base: Cl⁻(aq)
Base: CO₃⁻²(aq), conjugate acid: HCO₃⁻(aq)
The rewrite reaction is shown below.
Explanation:
The acid compound is the one that loses an H⁺, and the compound formed when it happens is its conjugate base. The base compound is the acceptor of H⁺, and its conjugate acid is the compound formed (Brosted-Lowry theory).
So, the acid-base pairs are:
Acid: HCl(aq), conjugate base: Cl⁻(aq)
Base: CO₃⁻²(aq), conjugate acid: HCO₃⁻(aq)
The TUMS® is an antacid, so it intends to reduce the concentration of the strong acid HCl. So, the forward reaction is favored. It can be represented with the forward arrow larger than the reversible arrow, as shown in the image below.
Answer:
Nuclear reactions involve a change in an atom's nucleus, usually producing a different element. Chemical changes involve only a rearrangement of electrons.

Answer:
<h2>75 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volume
From the question we have
mass = 5 × 15
We have the final answer as
<h3>75 g</h3>

Answer:
10 electrons.
Explanation:
Hello!
In this case, since a normal atom of magnesium has 12 protons and electrons when is not in the form of a cation, since it is a metal that tends to lose electrons when ionized, and therefore it becomes positively charged, we infer that in form of:
It only has 10 electrons.

<span>Moles of Cu = 2.10 /21 = 0.1 Moles of Ag produced is 0.2 Mass of Ag = 0.2 x 108 = 21.6 g.
0.500 g/108 = 0.046 moles, but Cu. moles produced will be half as much, from equation = 0.23moles
mass of Cu = 0.023 x2.10 = 0.0483g</span>
