6. Determine the pH of a 0.1 M solution of the following salts. a. (CH) NH2CHOO b. (CH) NH, HS

Assume the reaction of 51.47 g of Ge in the following reaction to determine the other quantities. 3Ge + 2N2 - > 1Ge3N4 moles of Ge reacting = mol moles of N2 required = mol moles of Ge3N4 formed = mol mass of Ge3N4 formed = g

In a calorimeter, 35 g of ice melts with a heat of fusion of 334 J/g. How much heat is absorbed?

In the combined gas law, if the volume is decreased, what happens to the temperature if pressure remains constant? a. The temperature decreases. b. The temperature increases. c. The temperature remains the same.

What is a definition of a Balanced Equation

Write out the balanced equation for the reaction that occurs when Al (OH) 3 and H2SO4 react together. You do not need to make your subscripts smaller; just write them out at regular numbers. For example: Al (OH) 3.

If you change the state of something, say, liquid to solid, is it a physical or chemical change?

What type of calorimeter would be best to use if you wanted to measure the heat that is released when gasoline is burned?

Tina has a sample of gaseous water at a temperature of 400 C and a pressure of 4 atm. If Tina increases the pressure to 200 atm, will the gaseous water liquefy? Why or why not?

Label the molecular shape around each of the central atoms in the amino acid glycine. hint

Which has more atoms, 2moles of carbon or 2 moles of aluminum
