Answer:
70g
Explanation:
Rate = 35g of NaCl can dissolve in 100g of H2O
Use proportions for 200g of H2O:
Since 200 is double of 100, x needs to be double of 35.
Therefore the maximum amount of NaCl that can dissolve in 200g of water is 70g.

D.
phenotype; genotype
Answer: Option B
Explanation: Any organism can be defined by two factors one is its genotype and other one is its phenotype.
The genetic composition of the body of an organism can be said as its genotype. The genes are present inside the cell and determines the physical characters of an organism.

Calcium and Nitrogen
So first you record the initial amount of the water before putting in the object. Then you put in the object and record the number where the water is at. The using that number subtract the initial amount from the final and then that will be the fluid displacement of the object.
Answer:
m Br = 439.472 g
Explanation:
mass Br = ?
∴ mol Br = 5.50 mol
∴ molar mass Br 79.904 g/mol
mass = (mol)*(g/mol)
⇒ m Br = (5.50 mol)*(79.904 g/mol)
⇒ m Br = 439.472 g
