The balanced chemical equation would be as follows:
<span>K2PtCl4(aq) + 2NH3(aq) --> Pt(NH3)2Cl2(s) + 2KCl(aq)
We are given the amount of </span>K2PtCl4 to be used in the reaction. This will be the starting point for our calculations. We do as follows:
65 g K2PtCl4 ( 1 mol / 415.09 g ) ( 1 mol Pt(NH3)2Cl2 / 1 mol K2PtCl ) ( 300.051 g / 1 mol ) = 46.99 g Pt(NH3)2Cl produced
Answer : Option A) The body breaks down the molecules into molecules they need.
Explanation : Nutrient molecules are important because the body breaks the nutrient molecules and convert it into the absorb-able molecule that can generate energy for doing the activities of the body.
Nutrients are taken in the body in the form of carbohydrates which later on gets broken into glucose molecules and generates energy, proteins which is decomposed into amino acids, fats breaks down into fatty acids, minerals and salts are also nutrients which is essential nutrient for body.
CaCl₂ is the chemical formula of calcium chloride, and its molar mass is 110.983 g/mol. It is an ionic compound comprising two chlorine anions and calcium cation. The bivalent calcium metal produces an ionic bond with two chlorine atoms. Calcium chloride is found in nature in its hydrated forms. It also occurs in huge concentrations in natural brine from salt deposits and salt lakes.
Calcium chloride is found as granules or flakes, as an odorless white powder. It exhibits a melting point of 782 degree Celsius, density of 2.15 g/ml, and a high boiling point of over 1600 degree Celsius.
