What's the average of 627.6 and 62.76

John Dalton believed which of the following about atoms?

If you spill 4.13 moles of water, H20, how many moles are in the puddle?

The atomic number tells you the number of what in one atom of an element?

4. Nitrogen and oxygen gases react to form dinitrogen monoxide gas (N2O). What volume of O, is needed to produce 34 L of N, O? I 2 N2 + O2 → 2N20

Given 4.8 moles of a gas in a 1.8 L container, if the temperature is found to be 31 degrees Celsius, what is the pressure of the gas? (The ideal gas constant is 0.0821 L · atm/mol · K and 1 atm = 760 torr.) 6.79 torr 66.55 torr 6.79 x 100 atm 6.

Write this number to two significant figures in scientific notation. Use the "^" character to indicate the exponent. 4.253

AN atoms nucleus contains it's protons and electrons true or false

What is the difference between parent geometry and actual geometry

The volume of a gas is halved and the temperature is unchanged. The pressure of the gas is
