Magnesium hydroxide decomposes on heating, forming magnesium oxide and water: Mg(OH)2 (s) ---) MgO (s) + H2O (g)
When a sample of Mg(OH)2 was heated in a crucible over a Bunsen burner flame, the weight of the crucible and its contents went from
43.77 g to 49.51 g. How many grams of MgO were produced?

Measuring which physical property is most likely to produce the most precise results when trying to identify a substance

If two atoms are bonded to a central atom with no lone pairs,how will they be arranged

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
