What is the new concentration of a solution of CaSO3 if 10.0 mL of a 2.0 M CaSO3 solution is diluted to 100 ml?
kifflom [539]

Answer: The new concentration of a solution of CaSO_{3} is 0.2 M 10.0 mL of a 2.0 M CaSO_{3} solution is diluted to 100 mL.

Explanation:

Given: V_{1} = 10.0 mL,      M_{1} = 2.0 M

V_{2} = 100 mL,           M_{2} = ?

Formula used to calculate the new concentration is as follows.

M_{1}V_{1} = M_{2}V_{2}

Substitute the values into above formula as follows.

M_{1}V_{1} = M_{2}V_{2}\\10.0 mL \times 2.0 M = M_{2} \times 100 mL\\M_{2} = 0.2 M

Thus, we can conclude that the new concentration of a solution of CaSO_{3} is 0.2 M 10.0 mL of a 2.0 M CaSO_{3} solution is diluted to 100 mL.

The absolute temperature of a gas is increased four times while maintaining a constant volume. What happens to the pressure of
lianna [129]

Answer:

DECREASE BY A FACTOR OF FOUR

Explanation:

Using pressure equation:

P 1 / T1 = P2 /T2     (at constant volume)

P1 = P

T1 =T

P2 = ?

T2 = 4 T

So therefore;

P2 = P1T1/ T2

P2 = P T/ 4 T

P2 = 1/4 P

The pressure is decreased by a factor of four, the new pressure is a quarter of the formal pressure of the gas.

What are two methods of writing a balanced formula?
Irina-Kira [14]
Format Method - Writing the symbol of the cation and then the anion. Add whatever subscripts in order to balance the charges.

Crisscross Method - The numerical value of the charge of each ion is crossed over and becomes the subscripts for the other ion.

Which of the following is true regarding the law of conservation of mass
Luda [366]
These are the answer options of this question and the comments about their validity:

<span>A) It dictates that the number of molecules on each side of a chemical equation must be the same.

False: the number of molecules can change. Take this simple reaction for example:

2H2(g) +  O2 -> 2H2O

You start with 3 molecules, 2 molecules of H2 and 1 molecule of O2, and end with 2 molecules of water. Then the number of molecules of each side is different.



B) It dictates that the number of atoms of each element must be the same on both sides of a chemical equation.

TRUE: in a chemical reaction the atoms remain being the same at start and at the end of the process. Given that each atom has a characteristic mass, their conservation implies the law of conservation mass.


C) It states that the mass of the reactants must remain constant in order for a chemical reaction to proceed.

FALSE. The mass of the reactants changes during a chemical reaction, while they transform into the products.

D) It does not apply to chemical reactions.

FALSE: It is an important law used in the calculus related with chemical reactions.
