Ca(OH)₂(s) precipitates when a 1.0 g sample of CaC₂(s) is added to 1.0 L of distilled water at room temperature. If a 0.064 g sample of CaC₂(s) (molar mass 64 g/mol) is used instead and all of it reacts, which of the following will occur and why?
(The value of for Ca(OH)₂ is 8.0 × 10⁻⁸.) of the carbon atoms c
(A) Ca(OH)₂ will precipitate because Q > .
(B) Ca(OH)₂ will precipitate because Q < .
(C) Ca(OH)₂ will not precipitate because Q > .
(D) Ca(OH)₂ will not precipitate because Q < .

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
