Answer: 1 mol of oxygen, O₂, and 1 mol of CO will have the same number of molecules, and the same number of atoms.
Justification:
Althought the question is too open, other answers may arise, the most remarkable similarity between the two compounds is that both are diatomic.
That means that both molecules oxygen, O₂, and carbon monoxide, CO have two atoms.
So, 1 mol of oxygen, O₂, and 1 mol of CO will have the same number of molecules, and the same number of atoms.
You must remember that 1 mol means a specific number. It is Avogadro's number, which is 6.022 × 10 ²³.
So 1 mol of CO and 1 mol of O₂ are the same number of representative particles: 6.022 ×10²³ molecules eac, and two times that number of atoms each (since each molecule has two atoms).
Answer:
The elements are arranged in seven horizontal rows, called periods or series, and 18 vertical columns, called groups.
Explanation:
Calcium. this is because Mg and calcium is in the same group. hence, they have similar chemical properties

Answer:
1550.8
Explanation:
This is the ideal gas equation:
PV=nRT
We can rearrange the ideal gas equation to solve for the pressure of the nitrogen gas.
P=nRT/ V
We can find the pressure of the nitrogen gas by plugging in the values for the moles of gas, temperature, and volume. Since we want the pressure in units of Torr we use the R value62.36358L Torr K−1 mol-1
P=nRT/ V
(0.316 mol )(62.36358 L*Torr/K*mol)(315 K) / 4.00 L =1550 Torr
The correct answer is 1550
