ASAP SHOW WORK FOR ALL what is the molarity of a solution that contains 1.56 moles of MgBr2 in 3.67 L of solution

What volume L of a 2.56 M solution would contain 2.456 Grams of Mg3(PO4)2

how many freaks of Cr2O3 are dissolved in 987 grams of water in 0.478 m of solution of Cr2O3

how many kilograms of solvent would contain 189 grams of NiBr2 if the solution was 1.62m

In a laboratory experiment, a fermenting aqueous solution of glucose and yeast produces carbon dioxide gas and ethanol. the solution was heated by burning natural gas in a bunsen burner to distill the ethanol that formed in the flask. during the distillation, the ethanol evaporated and then condensed in the receiving flask. the flame of the burner was kept too close to the bottom of the flask and some of the glucose decomposed into a black carbon deposit on the inside of the flask. during this experiment the following changes occurred. which of these changes involved a physical change and not a chemical change? check all that apply. 1-condensation of ethanol 2-evaporation of ethanol 3- formation of carbon dioxide gas from glucose burning of natural gas 4-formation of ethanol from glucose by yeast 5-formation of a carbon deposit inside the flask

If you add 10ml of hot water to 10ml of cold water and the change in tempature 8°c calculate how much energy is gained by the cold water

Which metal exist in liquid state and can be cut with knife ?
