Answer:
52.5 g of the salt
Explanation:
From the question given above, we were told that concentration of the mixture that is needed can be obtained as by dissolving 35 g of salt in 1000 mL of water.
Thus, we can obtain the mass of the salt needed to make 1500 mL of the salt water mixture as follow:
35 g of salt dissolves in 1000 mL of water.
Therefore, Xg of the salt will dissolve in 1500 mL of water i.e
Xg of salt = (35 × 1500)/1000
Xg of salt = 52.5 g
Thus, 52.5 g of the salt is needed to make 1500 mL of the salt water mixture.

<span>If Variable A is increased, Variable B will increase too. In a direct relationship, the two variables move in the same direction - if one increases, the other does too, and vice versa. In an inverse relationship, the two variables move in opposite directions - if one increases, the other decreases.</span>
Answer: third option: <span>have a full outer electron shell.
Explanation:
Noble gases is the family name given to the elements of group 18 of the periodic table.
The electron valence shell of all these elements is full:
He has two electrons wich is the maximum an atom of the first row can have.
Ne, Ar, Kr, Xe, and Rn (well you can include Og which is the last noble gas discovered; it is the element number 118), have 8 electrons on their valence electron shell, which is the maximum any element can have.
Precisely, that feature (valence shell full) accounts for the low reactivity of these elements, which conferred them the title of nobles (they hardly combine with other elements to form compounds).

Answer:
speed = 12.353 m/s
Explanation:
distance = 63 m
time = 5.1 s
substitute the values into the formula
speed = 12.353 m/s
