In a neutral atom they are both equal, and their even quantities makes the atom neutral...
Q= mcΔT
1623 = 33.69g x c x (110.8 - 29.4)
1623 = 2742.366 g•°C x c
c = 0.59j/g•°C
Answer:
d)
Explanation:
in one mole of phosphoric acid you have 3 mol hydrogen, 2 mol phosphorus, and 4 mol oxygen. just multiply everything by 2 and you get 2 mol of phosphoric acid
Answer:
b) O2, because it has weaker intermolecular forces
Explanation:
The preassure is produced by the collisions of the gas molecules with the walls of its container.
When the intermolecular forces between the gas molecules increase, those molecules start to "slow down" by effect of the interactions. The collisions decrease in frequency and intensity producing a smaller preassure in the container.
Both O2 and Cl2 are non-polar gases and the only intermolecular forces they have are the London ones. Given that the O2 molecules are smaller than the Cl2, the last ones attract each other with more strengh.
Being all that said, the container with the oxygen is expected to have a higher preassure.
