Answer:
1
Explanation:
For an ideal gas, the average kinetic energy is given by:
Ek = (3/2)*n*R*T
Where n is the number of moles, R is the gas constant (8.31 J/mol*K), and T the temperature. The gases have the same number of moles, and the same temperature, so they will have the same average kinetic energy:
Ek = (3/2)*1*8.31*300
Ek =3739.5 J
So, the ratio between then is 1.
The answer is "elements" :)
Answer:
Here's what I get.
Explanation:
- If your teachers don't ask for a specific type of formula, a condensed structural formula should be OK.
- If they ask specifically for a structural formula or a bond-line formula, that is what you must give.
Bottom line: ask your teachers in advance what they expect.
They have the same density because a material, no matter how much of it there is, will always be a certain density. A 40g ball of iron has the same density as a 1g ball of iron.
Answer:C
Explanation: The mass is still the same even though they took it apart.
