In astrophysics, M = m - 5 log(d/10)
where
m - apparent magnitude
<span>M - absolute magnitude </span>
<span>m - apparent magnitude </span>
<span>d - distance measured in parsec </span>
Answer:
The third one.
Explanation:
It goes from one reactant to two products.
Answer:
1. CO₂ → C + O₂
2. Fe₂ + O₂ → 2FeO
3. 2Al + 3CuO→ Al₂O₃ + 3Cu
Explanation:
1. 1 mol of CO₂ decomposes to 1 mol of C and 1 mol of oxygem
2. 1 mol of Fe₂ reacts with 1 mol of oxygen to produce 2 moles of iron (II) oxide
3. 2 moles of Al, reacts with 3 moles of cupper(II) oxide to produce 1 mol of aluminum dioxide and 3 moles of cupper
The solubility curve is a plot of solubility against temperature.
<h3>What is solubility?</h3>
The term solubility refers to the amount of substance that dissolves in solution at a given temperature. Hence, the solubility curve is a plot of solubility against temperature.
Thus, from the solubility curve (not shown) the amount if HCl dissolved can be obtained hence the question is incomplete.
