Explanation:
Reliability can be improved by completing each temperature more than once and calculating an average.
Answer: The three end products of the oxidation-reduction reactions involved in metabolism are WATER, CARBON DIOXIDE and ATP.
Metabolism refers to the sum of all chemical reactions occurring in the body. It includes both catabolism and anabolism. Every metabolic reaction is characterized by oxidation-reduction reactions. The metabolic pathways include respiration, photosynthesis, etc. In all these reactions water is produced. In respiration CO2 is also a product. In general. in every metabolic reaction either an organic molecule is broken or synthesized producing CO2, water and energy.
How small the unit of measurement is. The smaller the unit of measurement the more precise it is.
Answer:
c) 0.145
Explanation:
By Raoult's Law, the pressure of a solution is equal to the molar fraction of the solvent multiplied by its vapor pressure. The solvent here is ether, so
342 = x*400
x = 342/400
x = 0.855
The solution has only ether and benzoic acid, so the molar fraction of benzoic acid will be
1 - 0.855 = 0.145
Answer: Ca(NO3)2(s) -> Ca2+(aq) + 2NO3-(aq)
