Problem- If the concentration of an aqueous magnesium hydroxide solution in a test tube were given as (7.35x10^-1) microgram/mL what is the molarity of the magnesium hydroxide in the test tube
Please give an idea about how you obtained the answer
Presume a reaction occurs in which 38mL of O2 (g) is created in a vessel at a temperature of 28C as well as pressure of 740 mm Hg. Explain how many moles of O2 were created
Find the amount of heat involved when 300.4 g of propane is burned with an excess of oxygen. C3H8(g) + 3 O2(g) ? 3 CO2(g) + 4 H2O(l) -->?H = -2219 kJ
Two half cells in a galvanic cell consist of one iron Fe solid electrode in a solution of iron II sulphate FeSO4 aq as well as a silver Ag solid electrode in a silver nitrate AgNO3 aq solution.
What is the concentration of [Cl?] in a solution of 10 mL of 12 M HCl when 6 mL of water is added?
Steam at 3MPa and 300oC exits a boiler and goes into a high pressure turbine in which it is expanded to 300kPa. The steam is then sent back to the boiler (constant pressure heat exchanger) and reheated to 300oC.
Match the quantum numbers with the corresponding shell and subshell or invalid if the quantum numbers are not a valid set.
What are the values of Delta H degree and Delta S degree for dissolution of PbI2? PbI( s) rightarrow Pb^(2 +) ( aq) + 2 I^( -) (aq) You may assume that Delta H and Delta S are independent of temperature
