The pressure inside a container is 77 atm at a temperature of 57⁰C. What would the pressure be at 75^o C?

Which dissolving interaction is experienced when SI2 dissolves in NCl3?

How many electrons are required in the balanced half-reaction for the reduction of chromate ions tp chromium (iii) ions in basic solution?

What mass of sodium hydroxide is needed to produce 75g of sodium sulfate when reacted with excess sulphuric acid?

Aqueous silver ion reacts with aqueous solutions chloride ion to yield a white precipitate of solid silver chloride. When 10.0ml of 1.0M silver nitrate solution is added to 10.0ml of 1.0M of NaCl solution at 25°C in a calorimeter, a white precipitate of AgCl formed and the temperature of the aqueous mixture increases to 32.6°C. Assuming that, the specific heat of the mixture is 4.18JKg °C. The density of the mixture is |g|ml and thatbof the calorimeter itself absorbs a negligible amount of heat. Calculate the ∆H in KJ/mol for the reaction.
