We can find out how acidic or basic a substance is by using the pH scale. The greater the pH number is, the more basic the substance is. In order to convert from pOH to pH, we can use the equation pH = 14 - pOH. Our new pH values are then solution A = 12.5, solution B = 7.0, and solution C = 0.5. The answer is then solution A, because it has the greatest pH value.
Hope this helps!
Answer: it’s a 10kg barbell resting on the floor
Explanation:
This has the least gravitational potential energy
Answer:
g. H₂SO₄ + Ca(OH)₂ → CaSO₄ + 2H₂O.
Explanation:
Sulfuric acid is represented as H₂SO₄ and calcium hydroxide is represented as Ca(OH)₂.
- To balance a chemical reaction. we should apply the law of conservation of mass that the no. of different atoms in both sides (reactants and products).
- The only choice that represent the reactants correctly and apply the law of conversation of mass is:
<em>g. H₂SO₄ + Ca(OH)₂ → CaSO₄ + 2H₂O.</em>
<em></em>
<em>f. H₂SO₄ + 2Ca(OH)₂ → 2CaSO₄ + 3H₂O </em>
is not correct that the no. of S, and O is not equal in both reaction sides.
S in reactants (1) while in products (2).
<em>O in reactants (8) while in products (11).</em>
<em></em>
<em>h. HSO₄ + CaOH → CaSO₄ + H₂O</em>
The reactants is represented in a wrong way.
<em> j. H₂SO₄+ Ca(OH)₂ → CaSO₄ + H₂O</em>
is not correct that the no. of H and O is not equal in both reaction sides.
H in reactants (4) while in products (2).
O in reactants (6) while in products (5).
<em></em>
<em>So, the right choice is: g. H₂SO₄ + Ca(OH)₂ → CaSO₄ + 2H₂O.</em>
