The valve is opened allowing the gases to mix. Calculate the total pressure of the system; assume the temperature remains constant at 405 K. c. Once the gases have mixed and the pressure equilibrated to that calculated in part (c) which of thegases has the:i. Greatest average kinetic energy. Justify your answerii. Greatest velocity. Justify your answer

In a reaction (at equilibrium) that makes more moles of gas than it consumes, what is the effect of increasing the pressure?

Write the formula for the following chemicals. 7. e. trinitrogen tetraoxide a calcium phosphate f. magnesium acetate b. potassium sulfide g nickel(iii) cyanide c carbon dioxide h. silver sulfate d. cobalt(ii) chloride

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.
