Answer:
Chemical properties can be tested without changing the substance
Explanation:
To solve this we use the equation,
M1V1 = M2V2
where M1 is the concentration of the stock solution, V1 is the volume of the stock solution, M2 is the concentration of the new solution and V2 is its volume.
1.75 M x V1 = 0.100 M x 2.0 L
V1 = -.11 L
Answer : The volume of stock solution is, 0.114 L
Solution :
According to the dilution law,
where,
= molarity of solution = 0.100 M
= volume of solution = 2.00 L
= molarity of stock solution = 1.75 M
= volume of stock solution = ?
Now put all the given values in the above law, we get the volume of stock solution.
Therefore, the volume of stock solution is, 0.114 L
(1) factory workers from the Northeast to the
Sun Belt
(2) communists deported to Russia as
undesirable aliens
(3) African Americans to northern cities to find
work
(4) refugees fleeing from eastern Europe to the
United States
The Great Migration during World War I refers to the movement of African Americans to northern cities to find work. Therefore, option (3) is correct.
The Great Migration was the movement of millions of African Americans moved from the rural Southern United States to the urban Northeast, Midwest, and West. The great migration was caused by the poor economic conditions for African American people.
The historic change brought by the migration was fueled because the migrants moved to the largest cities in the United States such as New York City, Chicago, Los Angeles, Philadelphia, Cleveland, and Washington, D.C. at a time when these cities had a central social, political, cultural and economic influence over the United States.
African Americans established effective communities of their own. Therefore the Great migration movement was actually sending African Americans to northerncities to find work.

Answer:
grams per milliliter.
Explanation:
While any units of mass and volume can be used to calculate density the most common are grams (g) and milliliters (ml). This gives density the units of grams per milliliter (g/ml).
