What is the ionic equation for this reaction: MgO (s) + 2HCl (aq) = MgCl2 (aq) + H2O (l)

Please let me know how you worked it out, thankyou!!

Summarize possible ways in which phases of matter could combine to form a solution.

Consider the following reaction at equilibrium. 2co2 (g) 2co (g) + o2 (g) h° = -514 kj le châtelier's principle predicts that the equilibrium partial pressure of co (g) can be maximized by carrying out the reaction a. at high temperature and high pressure b. at high temperature and low pressure c. at low temperature and low pressure d. at low temperature and high pressure e. in the presence of solid carbon

What is the lowest number energy level where a d sublevel is found
