For a gas in closed chamber indicate what happens (Increase or decrease) to the fowling change Increase T : Increase moles : decrease volume : add an additional gas:
Two gas tanks are linked by a connecting tube of negligible volume with a valve. One contains 15 L of nitrogen at 7.2 atm of pressure. The other contains 8.3 L of helium at 4.1 atm of pressure.
Write a balanced equation for the decomposition reaction described, using the smallest possible integer coefficients. When calcium carbonate decomposes, calcium oxide and carbon dioxide are formed.
What was the pH at the end of the reaction? e) What would the final pH be in the absence of any buffer?
