If you have a beaker of gas and all of the gas in that beaker is moved to a container half the size, the temp is maintained, what would the gas look like
Combustion of natural gas (primarily methane) occurs in most household heaters. The heat given off in this reaction is used to raise the temperature of the air in the house.
A reaction mixture initially contains .56 atm CO2 and .32 atm CO. what is the equilibrium pressure of CO
What is the molarity of a calcium hydroxide solution if a 25.0 mL sample is exaclty neutralized by 42.5 mL of 0.0750 M nitric acid?
Calcium in blood or urine can be determined by precipitation as calcium oxalate CaC2O4. The precipitate is dissolved in strong acid and titrated with potassium permanganate. The products of the reaction are carbon dioxide and Manganese ii ions.
A solution is made by combining 10.0mL of 17.5M acetic acid with 5.50g of sodium acetate and diluting to a total volume of 1.50L
A person ate 0.516 pound of cheese (an energy intake of 4130 kJ). Suppose that none of the energy was stored in his body. What mass (in grams) of water would he need to perspire in order to maintain his original temperature? (It takes 44.0 kJ to v..
