The answer is A) heterogeneous mixtures, look up how a heterogeneous mixture is separated and it will tell you distillation. Have a nice day and good luck on the rest of your work
Answer:
Five significant figures
Explanation:
You have to change the number to standard form
340500 = 3.405×10**5
** means raise to power
10**5
Where five represents the number of significant figures.
Answer:
4!
Explanation:
(2) –2 (4) +17
The charge of the nucleus in an atom of oxygen is +8. The correct option is 3.
The charge is negative or positive or neutral charges present on the substance or molecule. The charges are produced by the gaining or losing of electrons.
The charges tell the tendency of the atom or molecule of gaining or losing of the atom.
Thus, the correct option is 3, +8.

2. The solid phase is relatively soluble.
3. The chemical reaction proceeds readily to the right.
4. The chemical reaction proceeds readily to the left.
Values of Ksp greater than 1.0 infer that the solid phase is relatively soluble. The answer is number 2. If Ksp is less than 1 then the solid phase is relatively insoluble.
a. True
b. False
Answer:
True. A gas does not have a definite volume. Therefore, making this statement correct.

the reduced substance is Cl2.
Answer:
3.3 liters of the mixture is needed to be removed and filled with 3.33 liters pure antifreeze to reach a concentration of 60% antifreeze.
Explanation:
A 10 L mixture is made up of 40% antifreeze.
Initial Volume of antifreeze in 40% mixture = 40% of 10 L = 4L
Let volume of pure antifreeze added = x
Volume of antifreeze removed = 40% of x= 0.4 x
Volume of antifreeze in 60% mixture = 60% of 10 L = 6 L
Volume of antifreeze left after removal of 0.4 x L of antifreeze and addition of x L of pure antifreeze will be equal to 6 L of antifreeze in the final solution.
4L - (0.4 x ) + x = 6L
x = 3.33 L
3.3 liters of the mixture is needed to be removed and filled with 3.3 liter pure antifreeze to reach a concentration of 60% antifreeze.
