i think A but if I'm wrong sorry
then if increasing then becoming spread out so letter A
Answer:
6
Explanation:
Formula: Al2O3
If we require 2Al2O3
We divide 2 by 3

Calcium acetate [Ca(C₂H₃O₂)₂] is strong electrolytes
<h3>What is the calcium acetate's mode of action?</h3>
End-stage renal disease patients on dialysis who have hyperphosphatemia (excess phosphate in the blood) are treated with calcium acetate. By forming a bond with the phosphate in your diet, calcium acetate causes it to leave your body without being absorbed.
Heat is created as calcium acetate dissolves in water, and as the temperature rises, the solubility of the calcium acetate increases.
When heated, calcium acetate, a somewhat water-soluble crystalline calcium source, breaks down to form calcium carbonate.

Answer:
41.4 g
Explanation:
2Na(s) + 2H2O (l) ----> 2NaOH ( aq) + H2 (g)
According to the above balnced chemical equation the ratio between moles of H2 gas formed to moles of Na used up is 1:2
Molar mass ( Mass of 1 mol) Of H2 gas is 2 gmol-1
So in 1.8 g of H2 0.9 mol should be present
Therefore no. of moles of Na used should be 2× 0.9 = 1.8 moles
Molar mass of Na= 23 gmol-1
So mass of 1.8 mol of Na = 1.8× 23 g = 41.4g
