Answer:
1.25 moles of HF
Explanation:
1 mole = 20.0 grams of HF
So, to calculate mass of 25.0 grams
=25.0*1/20.0
=1.25 moles
Answer:
b. protein
Explanation:
Proteins are biopolymers basically made of carbon, hydrogen, oxygen and nitrogen.
Triglycerides are made of a glycerol molecule esterified by three fatty acids.
Polysaccharides are carbohydrates, and therefore contain carbon, hydrogen, and oxygen.
The mineral salt contains mostly sodium chloride, although it contains some other minerals such as magnesium, potassium, iodine, among others.
For a chemical reaction, the results would be the same with different amounts of barium chloride present if barium chloride is not the limiting reactant of the reaction. The limiting reactant is the substance that is totally consumed when the reaction proceeds to completion. In other words, it dictates the amount of products that will be produced. Otherwise, if barium chloride is the limiting reactant, the amount of barium chloride present would definitely affect the results.
