The atomic number is equal to the number of protons
Answer:
See explanation.
Explanation:
Hello,
In this case, for the described chemical reaction:
2 HCl(aq) + Mg(OH)2(aq) → MgCl2(aq) + 2 H2O(l)
We can notice there is a 2:1 molar ratio between the moles of hydrochloric acid and magnesium hydroxide, therefore, at the equivalence point:
And in terms of volumes and concentrations we verify:
So we use the given data to proof it:
Therefore, we can conclude the data is wrong by means of the 2:1 mole ratio that for sure was not taken into account. This is also supported by the fact that normalities are actually the same, but the nomality of magnesium hydroxide is the half of the hydrochloric acid normality since the acid is monoprotic and the base has two hydroxyl ions.
Best regards.
Answer:
It rains because the water gets evaporated into earth's atmosphere and turned into small water gas droplets and it turns into clouds. the clouds get too heavy and start to spill water.
Answer:
If the temperature gets low enough it may freeze or get frosty, and if it gets high enough it will melt or boil. The color may even change if it freezes or gets burnt, and the smell may change.
Explanation:
The temperature will affect the state, color, and even smell of a substance based on the substances' sensitivity to heat or cold.
