Answer:
8.0 g
Explanation:
To convert moles to grams, you need to use the molar mass. The molar mass of sulfur is 32.06. The molar mass is the atomic mass of the atom.
(0.25 mol) × (32.06 g/mol) = 8.015 g
Round for significant figures.
8.015 g ≈ 8.0 g
Answer: The E for Silver-silver Chloride electrode = 0.287 V
Explanation:
Silver/Silver Chloride (Ag/AgCl) with a value for E° that is actually +0.222 V or approximately 0.23 V has the actual potential of the half-cell prepared in this way as +0.197 V vs SHE, (Standard Hydrogen Electrode) which arises because in addition to KCl, there is the contribuion of AgCl to the chloride activity, which isn't exactly unity.
Therefore, the E for the Ag/AgCl electrode would approximately equal 0.287 V
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.
