<u>Answer:</u> The correct answer is Option B.
<u>Explanation:</u>
There are 3 sub-atomic particles present in an atom. They are: Electrons, protons and neutrons.
- <u>Electrons:</u> They are negatively charged particles and are present around the nucleus in the orbits.
- <u>Protons:</u> They are positively charged particles and are present inside the nucleus of an atom.
- <u>Neutrons:</u> They are neutral particles which means they do not carry any charge. They are present in the nucleus of an atom.
Hence, the correct answer is Option B.
Answer:
I think D.
Explanation:
The substances in a mixture are separated by the differences in their physical properties, such as their particle size. The more different the properties are, the easier it is to separate the substances.
Answer:
96.09 g/mol
Explanation:
You just need to first get the atomic weights of the elements involved. You can easily get these from your periodic table.
If you are going to do this properly, please use the weight with at least two decimal places for accuracy (e.g. 15.99 g/mol).
Also, please take note that I will be using the unit g/mol for all the weights. Thus,
Step 1
N = 14.01 g/mol
H = 1.008 g/mol
O = 16.00 g/mol
C = 12.01 g/mol
Since your compound is
(
N
H
4
)
2
C
O
3
, you need to multiply the atomic weights by their subscripts. Therefore,
Step 2
N = 14.01 g/mol × 2 =
28.02 g/mol
H = 1.008 g/mol × (4×2) =
8.064 g/mol
O = 16.00 g/mol × 3 =
48.00 g/mol
C = 12.01 g/mol × 1 =
12.00 g/mol
To get the mass of the substance, we need to add all the weights from Step 2.
Step 3
molar mass of
(
NH
4
)
2
CO
3
=
(28.02 + 8.064 + 48.00 + 12.01) g/mol
=
96.09 g/mol
this is a google search and a example i hope is helps to solve
Answer:2
Explanation:
This way they will balance.
Vapor Pressure: Measures how a substance is likey to evaporate
Surface Tension: is the attraction between liquid molecules.
Plasma: is an organic and inorganic substance that is typically found in blood
