Ok so this all boils down to Newton's second law
Force = mass X acceleration
so the force = 10 X 3 = 30N
An example of a general formula of an acid is
<span>HCl
This is called as hydrochloric acid or hydrogen chloride.
H represents for the atom of Hydrogen
and Cl represents for the atom of Chlorine
Since their charges are -1, and +1, it's ratio is 1:1</span>
Answer:
Indeed, the two samples should contain about the same number of gas particles. However, the molar mass of is larger than that of (by a factor of about .) Therefore, the mass of the sample is significantly larger than that of the sample.
Explanation:
The and the sample here are under the same pressure and temperature, and have the same volume. Indeed, if both gases are ideal, then by Avogadro's Law, the two samples would contain the same number of gas particles ( and molecules, respectively.) That is:
.
Note that the mass of a gas is different from the number of gas particles in it. In particular, if all particles in this gas have a molar mass of , then:
.
In other words,
- .
- .
The ratio between the mass of the and that of the sample would be:
.
Since by Avogadro's Law:
.
Look up relative atomic mass data on a modern periodic table:
Therefore:
- .
- .
Verify whether :
- Left-hand side: .
- Right-hand side: .
Note that the mass of the sample comes with only two significant figures. The two sides of this equations would indeed be equal if both values are rounded to two significant figures.
Answer:
C
Explanation:
radiation from the sun first warms the outer atmosphere (trophosphere)
convection(aka just heat moving through gas or liquid) brings the warmth down lower
conduction heats the ground
gl lol :))
