Answer:
Option 1.
Explanation:
When we warm up, our heart rate increases and we require much more energy to continue. Hence, our body absorbs much more oxygen from the surroundings, digest food and etc.
Sorry if the explanation might sound wrong, I learned this during science 2 years ago so I forgot.
The normality is the ratio of the equivalent to the volume of the solvent. To the mixture, 1.182 gms of magnesium should be added.
<h3>What is Normality?</h3>
Normality (N) is the grams or moles of solute per liter of solution.
Magnesium has 2 valence electrons in the outermost shell so,
1 mEq of Mg⁻² ions = atomic number of Mg ÷ valence electron
= 12 ÷ 2
= 6 mg
In a liter solution having 197 meq/l of Mg⁻²:
197 meq/l of Mg⁻² × 6 = 1182 mg
Therefore, 1.182 gms of magnesium ions should be added to the mixture.
