Answer:
75.924 g
Explanation:
To answer this question we first need to calculate the molar mass of Ga₂(SO₃)₃:
Molar Mass of Ga₂(SO₃)₃ = (Molar Mass of Ga)*2 + (Molar Mass of SO₃)*3
Molar Mass of SO₃ = Molar Mass of S + (Molar Mass of O)*3 = 80.06 g/molMolar Mass of Ga₂(SO₃)₃ = (69.72 g/mol)*2 + (80.06 g/mol) * 3
Molar Mass of Ga₂(SO₃)₃ = 379.62 g/molThen we convert 0.20 moles to grams, using the molar mass of Ga₂(SO₃)₃:
0.20 mol Ga₂(SO₃)₃ * 379.62 g/mol = 75.924 gMass of 0.20 moles of Ga₂(SO₃)₃ is 75.924 g
Number of moles:It is defined as the ratio of given mass over molar mass.
Given:
Number of moles= 0.20 moles
To find:
Mass=?
We need to calculate molar mass of Ga₂(SO₃)₃ first:
Molar Mass of Ga₂(SO₃)₃ = (Molar Mass of Ga)*2 + (Molar Mass of SO₃)*3
Molar Mass of SO₃ = Molar Mass of S + (Molar Mass of O)*3 = 80.06 g/mol
Molar Mass of Ga_2(SO_3)_3 = (69.72 g/mol)*2 + (80.06 g/mol) * 3
Molar Mass of Ga₂(SO₃)₃ = 379.62 g/mol
Then we convert 0.20 moles to grams, using the molar mass of Ga₂(SO₃)₃:
[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}} \\\\\text{Given mass}=\text{Number of moles}*\text{Molar mass}\\\\\text{Given mass}=0.20 moles*379.62 g/mol\\\\\text{Given mass}=75.92 grams\\[/tex]
Thus, the mass of 0.20 moles of Ga₂(SO₃)₃ is 75.92 grams.

_______ are white blood cells that recognize specific antigens, and ultimately destroy them.
O lymphocytes
O pathogens
O water
Answer:
Lymphocytes
Explanation:
Pathogens are particles that make you sick like bacteria, viruses, amoebas. Water is essential for life but that's for metabolism, not fighting off against infection or viruses.
Answer:
Lymphocytes
Explanation:
lymphocytes are a kind of white blood cell (WBC). Lymphocytes are cells of the immune system and help fight infection. Lymphocytes live in lymph nodes, but also in the bloodstream and all over the body. Lymphocytes come in two main types: B-cells and T-cells
Where as water is totally not white blood cells and pathogens are viruses and bacterium

The waste product of nuclear energy which is a possible pollutant is:
A.smoke
B.hot air
C.radiation
D.heat pollution to lake
Answer:
CCCCCCC
Explanation:
Answer:
C. radiation
Explanation:
the possible pollutant is radiation because nuclear energy causes ; electromagnetic waves are radio waves, light, infrared rays, UV rays, X rays, Gamma rays. These are well known and are used extensively in the fields of communications, industry, medicine and research.
Radiation is a term given for waves caused by electromagnetism and high energy particles .Radioactive substances have High energy particles which are tiny bits of matter that are made to move at high speeds releasing nuclear radiation. There are about 50 naturally occurring radioactive substances and More than 2000 man-made ones. There are three kinds of radioactive radiation – alpha particles, beta particles and gamma radiation.
The answer to the problem: (2.1x103) x (4x105) = _____, written to the correct number of significant digits and in scientific notation is:
!! Carat denotes to the power. Example: 10^4 is 104 !!
Answer: The answer is [tex]8.4\times 10^8[/tex]
Explanation:
Significant figures : The figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.
The rule apply for the multiplication and division is :
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
Thus for product of [tex](2.1\times 10^3)\times (4\times 10^5)[/tex]
In this problem, 2.1has 2 significant figures and 4 is an exact number with infinite significant digits thus product will have the least number of significant figures which is 2. So, the answer will be in 2 significant figures.
Therefore, the answer is [tex]8.4\times 10^8[/tex]

When a mixture of rock pieces, salt and water is filtered, what will be found as the filtrate and what will be found as the residue
Answer:
Filtrate: Mixture of salt and water.
Residue: rock pieces
Answer:
Salt solution will be the filtrate
and the rock pieces will be the residue.
Explanation:
This is because salt is soluble in water and hence
it cannot be filtered out of water giving as a salt solution as the filtrate and since the rock pieces are not soluble in water they are left out and they become the residue.
