Think about the lab procedure you just read.
Label each factor below with V for "variable" or
C for "constant".
The temperature of the gas:
The amount of gas in the tube (in terms of
mass and moles):
The radius of the tube:
The temperature of the gas (changed by the
water surrounding it):
The type of gas:
The pressure of the gas:

If 1.63 times 10 negative 4 of helium dissolves in 100.0g of water, what is the concentration in parts per million

Asample of ammonia reacts with oxygen as shown. 4nh3(g) + 5o2(g) 4no(g) + 6h2o(g) what is the limiting reactant if 4.0 g of nh3 react with 8.0 g of oxygen? o2 because it produces only 0.20 mol of no. nh3 because it produces only 0.20 mol of no. o2 because it produces two times less no than nh3. nh3 because it produces three times more no than o2.

Use the periodic table to determine the electron configuration of dysprosium (dy) and americium (am) in noble-gas notation.
