What is the molarity of a solution prepared by dissolving 11.5g of solid NaOH in enough water to make 1.50L of solution?
Predict whether, to any significant extent, MnO-4(aq) will oxidize Cl-(aq) to Cl2(aq) in acidic solution, The reaction is spontaneous under standard conditions
What mass of aluminum metal can be produced per hour in the electrolysis of a molten aluminum salt by a current of 21 A?
A 25ml sample of solution containing thallium(I) (TI) was treated with K2CrO4 to perticipate thallium chromate. The solid TI2CrO4 was filtered, washed to remove excess chromate, and then dissolved in dilute H2SO4
A 486 mL sample of water was cooled from 50.0°C to 10.0°C. Assuming a specific heat of 4.184 J/K g and a density of 1.00 g/mL, find the amount of heat transferred from the water to the surroundings.
Calculate the heat released when 2.57 L of Cl2(g) with a density of 1.88 g/L reacts with an excess of sodium metal at 25°C and 1 atm to form sodium chloride.
How should a professional emergency responder be concerned about the following routes of radiation exposure for a person on scene and a person downtown?
As it expands, it does 135.8 J of work on its surroundings at a constant pressure of 783 torr. What is the final volume of the gas?
Data Table: Mass MgO: 2.8045g initial temperature(°C): 24.99°C final temperature(°C): 25.00 °C Calculate the number of moles of MgO used in the reaction. The molar mass of MgO is 56.305 g/mole.
Calculate the theoretical yield of C_2H_5Cl when 127 g of C_2H_6 reacts with 250 g of Cl_2, assuming that C_2H_6 and Cl_2 react only to form C_2H_5Cl and HCl.
