Magnesium hydroxide Mg(OH)₂ is a weak base.
Explanation:
Sulfuric acid H₂SO₄ and hydrochloric acid HCl are, both of them, very strong acids.
Sodium hydroxide NaOH and potassium hydroxide KOH are hydroxides of metals from the first group in the periodic table so thy are strong bases.
As you go to the second group in the periodic table, the hydroxides will not dissociate as much as the hydroxides from the first group in the periodic table , so they will be weak bases. This is the case of magnesium hydroxide Mg(OH)₂.

The concentration of calcium carbonate does not appear in the rate law because it is a solid and its concentration is constant. The molar density, which is fixed, is the concentration of the solid. In this chemical reaction, only the amount of hydrochloric acid affects the rate of reaction.
The temperature is held constant at (b) and (d). At these points, the substance is changing states. B is changing from solid to liquid and D is changing from liquid to gas
Answer:
The student should weigh out 61.2g of ethanolamine [6.12 * 10]
Explanation:
In this question, we are expected to calculate the mass of ethanolamine needed to make 60.0ml of it given that the density of the ethanolamine in question is 1.02g/cm^3
Mathematically, it has been shown that mass = density * volume
Hence, by multiplying the density by the volume, we get the mass.
Now, from the question we can see that we have the values for the density and the volume. We now need to get the mass.
Since cm^3 is same as ml, we need not perform any conversion.
Hence, the needed mass is:
60 * 1.02 = 61.2g
