What are metal strips called that are inside the copper compound solution

What would be the resulting molarity of a solution made by dissolving 21.9 grams of KCl in enough water to make an 869-milliliter solution? Show all of the work needed to solve this problem.

Bromine has chemical properties most similar to ... A. fluorine B. potassium C. krypton D. mercury

A generic solid, X, has a molar mass of 78.2 g/mol. In a constant-pressure calorimeter, 12.6 g of X is dissolved in 337 g of water at 23.00 °C. X (s) yeilds X (aq) The temperature of the resulting solution rises to 24.40 °C.

For the reaction, calculate how many moles of the product form when 0.012 mol of O2 completely reacts. Assume that there is more than enough of the other reactant. 4Al (s) + 3O2 (g) →2Al2O3 (s) Express your answer using two significant figures.
