Answer:
28.16 g/mol
Explanation:
From Graham's law;
Let the rate of diffusion of gas X be 1.25
Let the rate of diffusion of CO2 be 1
Molecular mass of gas X= M
Molecular mass of CO2 = 44g/mol
1.25/1=√44/M
(1.25/1)^2 = 44/M
1.5625 = 44/M
M= 44/1.5625
M= 28.16 g/mol
19. The atomic number is the same as protons and electrons unless it have a - or a + charge the electrons are going to change
It is likely the neutral atom has 6 protons and 6 electrons; while the negatively charged atom has 7 or more electrons.
The mass of an atom, commonly known as the atomic mass is determined by the number of protons and neutrons as electrons have a very low mass.
This means two atoms can have the same number of protons and neutrons, but a different number of electrons, which would make the atom be charged negatively or positively.
Based on this, if there are two atoms, each with 6 protons but one of these is negatively charged it is because the second atom has 1 or more extra.
Neutral atom:
- This atom has 6 protons and an unknown number of neutrons located in the nucleus.
- This atom has 6 electrons that orbit the nucleus.
- The first energetic level will include 2 electrons while the second energetic level will include the 4 remaining electrons.
Negatively-charged atom:
- This atom has 6 protons and an unknown number of neutrons located in the nucleus.
- This atom has 7 or even more electrons that orbit the nucleus.
- The first energetic level will include 2 electrons while the second energetic level will include up to 8 electrons.

It would be c because it has to get hot so it is absorbing the heat not releasing it
Answer:
Empirical formula is CCl₄
Explanation:
Given data:
Percentage of carbon = 7.70%
Percentage of chlorine = 92.3%
Empirical formula = ?
Solution:
Number of gram atoms of Cl = 92.3 / 35.5 = 2.6
Number of gram atoms of C = 7.70 / 12 = 0.64
Atomic ratio:
C : Cl
0.64/0.64 : 2.6/0.64
1 : 4
C : Cl = 1 : 4
Empirical formula is CCl₄.
