Answer: 25.3
Explanation:
The question aks to convert 19 quibs, which is the amount of skvarnick that you obtained, to sleps.
Since, you are given the equivalence between sleps and quibs, you can build your own conversion factor, which is how the sciientific calculations are made:
- equivalence: 4 sleps = 3 quibs
- divide both sides by by 3 quibs: (4 sleps / 3 quibs) = (3 quibs / 3 quibs)
- simplify: 4 sleps / 3 quibs = 1 ← conversion factor
Now, you can multiply 19 quibs by the conversion factor:
- 19 quibs × 4 sleps / 3 quibs = 76 / 3 sleps ≈ 25.3 sleps. ← answer
The quibs units cancel out since they are in the numerator and denominator, leaving only sleps.
Here we have to get the item which has more thermal energy among the given options.
The item a) will have more thermal energy than b)
The thermal energy of a compound can be determined from the formula H = m×s×t (H = thermal energy, m = mass of the compound, s = specific heat of the compound, t = temperature)
a) Here m = 500 g, s = 1 g/mL and t = 50⁰C (as the density of water is 1 g/mL thus its volume is equivalent to its mass)
Thus the thermal energy H = 500 × 1 × 50 = 25000 Cal (The energy needed to raise 1⁰C temperature of 1g water is calorie unit)
similarly,
b) Here m = 100 g, s = 1 g/mL and t = 50⁰C (as the density of water is 1 g/mL thus its volume is equivalent to its mass)
Thus the thermal energy H = 100 × 1 × 50 = 5000 Cal (The energy needed to raise 1⁰C temperature of 1g water is calorie unit).
Thus option a) i.e. 500 mL of water at 50 degree Celsius will have more thermal energy.
Thus the thermal energy of both the item have calculated and compared.

<h3>Answer:</h3>
SALT
<h3>Explanation:</h3>
Salt is formed by the opposite ions bonded to each other through Ionic Bond. The two ions i.e. Cation and Anions are formed by oxidation and reduction reactions respectively. General dissociation of salt is represented as,
MN → Mⁿ⁺ + Nⁿ⁻
where;
Mⁿ⁺ = Cation
Nⁿ⁻ = Anion
MN = Salt
Following is the list of salts which when when dissociates produces Cations and Anions other than OH⁻ (Hydroxide) and H⁺ (Hydrogen Ion).
Magnesium Sulfate:
MgSO₄ → Mg²⁺ + SO₄²⁻
Sodium Chloride:
NaCl → Na⁺ + Cl⁻
Sodium Carbonate:
Na₂CO₃ → 2 Na⁺ + CO₃²⁻
Ammonium Dichlorate:
(NH₄)₂Cr₂O₇ → 2 NH₄⁺ + Cr₂O₇²⁻
