. Calcium hydroxide, Ca(OH)2, dissolves in water at 25 °C to the extent of 1.78 g L−1. What is the value of the solubility product Ksp of calcium hydroxide in water at that temperature? The molar mass of Ca(OH)2 is 74.093 g mol−1. A) 22.5 B) 1.39 × 10−5 C) 0.187 D) 5.55 × 10−5 E) 5.77 × 10−4

Answerit curves up and levels out.explanationwe assume that the container contains absolutely no ammonia to begin with as it states that "nitrogen gas and hydrogen gas" react to "produce ammonia."at dynamic equilibrium, the product and reactant concentrations are equal.this means that, starting from a concentration of zero, [nh₃] must curve "up" from zero and then level out to a constant concentration.

Answer    "a salt" would be the best answerexplanationsalts can be defined as ionic compounds that are neither acids nor bases. nacl is an example of a salt, and its ionic.an enzyme is an organic compound which is covalently bonded, not ionically bonded.acids are generally held together by covalent bondsan element does not need any bonds to exist
