If a flask initially contains 1.0 atm of A and 1.2 atm of B, what is the pressure in the flask if the reaction proceeds to completion? (Assume constant volume and temperature.) If a flask initially contains 1.0 of and 1.2 of , what is the pressure in the flask if the reaction proceeds to completion? (Assume constant volume and temperature.) 3.2 atm 2.2 atm 1.7 atm 1.2 atm

If the specific heat of a metal is 0.850 j/g °c, what is its atomic weight?

When doing scientific research ,the sources used should be ?

The lid of a pressure cooker forms a nearly airtight seal. steam builds up pressure and increases temperature within the pressure cooker so that food cooks faster than it does in an ordinary pot. the system is defined as the pressure cooker and the water and steam within it. if 2.0 g of water is sealed in a pressure cooker and then vaporized by heating, and 5127 j must be added as heat to completely vaporize the water, what is the change in the system’s internal energy? answer in units of j.
