<em>Different fluids have different boiling points depending on the bonding between the particles and the mass of the particles. The heavier the particles,  the stronger the bonding, the higher the boiling point will be.</em>

No, different liquids will boil at different temperatures due to a range of different variable such as  composition of liquid, pressure etc.

14. 60. g of NaOH is dissolved in enough distilled water to make 300 mL of a stock solution. What volumes of this solution and d
zepelin [54]

The question is incomplete, the complete question is attached below.

Answer : The volumes of stock solution and distilled water will be, 20 mL and 80 mL respectively.

Explanation : Given,

Mass of NaOH = 60 g

Volume of stock solution = 300 mL

Molar mass of NaOH = 40 g/mol

First we have to calculate the molarity of stock solution.

\text{Molarity}=\frac{\text{Mass of }NaOH\times 1000}{\text{Molar mass of }NaOH\times \text{Volume of solution (in mL)}}

Now put all the given values in this formula, we get:

\text{Molarity}=\frac{60g\times 1000}{40g/mole\times 300mL}=5mole/L=5M

Now we have to determine the volume of stock solution and distilled water mixed.

Formula used :

M_1V_1=M_2V_2

where,

M_1\text{ and }V_1 are the molarity and volume of stock solution.

M_2\text{ and }V_2 are the molarity and volume of diluted solution.

From data (A) :

M_1=5M\\V_1=20mL\\M_2=1M\\V_2=?

Putting values in above equation, we get:

5M\times 20mL=1M\times V_2\\\\V_2=100mL

Volume of stock solution = 20 mL

Volume of distilled water = 100 mL - 20 mL = 80 mL

From data (B) :

M_1=5M\\V_1=20mL\\M_2=1M\\V_2=?

Putting values in above equation, we get:

5M\times 20mL=1M\times V_2\\\\V_2=100mL

Volume of stock solution = 20 mL

Volume of distilled water = 100 mL - 20 mL = 80 mL

From data (C) :

M_1=5M\\V_1=60mL\\M_2=1M\\V_2=?

Putting values in above equation, we get:

5M\times 60mL=1M\times V_2\\\\V_2=300mL

Volume of stock solution = 60 mL

Volume of distilled water = 300 mL - 60 mL = 240 mL

From data (D) :

M_1=5M\\V_1=20mL\\M_2=1M\\V_2=?

Putting values in above equation, we get:

5M\times 60mL=1M\times V_2\\\\V_2=300mL

Volume of stock solution = 60 mL

Volume of distilled water = 300 mL - 60 mL = 240 mL

From this we conclude that, when 20 mL stock solution and 80 mL distilled water mixed then it will result in a solution that is approximately 1 M NaOH.

Hence, the volumes of stock solution and distilled water will be, 20 mL and 80 mL respectively.

Carl hits a baseball with a force of 8 N. The next batter, Stacy, hits it with 12 N of force. Which ball will accelerate faster?
Kisachek [45]

Answer:

The ball hit with 12 N

Explanation:

acceleration = Force/ mass

If masses of balls are the same, then more the force -  more acceleration.

12N more than 8N,

so the ball that hits Stacy accelerate faster.

How much ko2 is needed to react with 75.0 l of carbon dioxide at –25˚c and 215 kpa?
Anettt [7]
First, we convert the pressure in kPa to atm. That is,
                             (215 kPa) x (1 atm/ 101.325 kPa) = 2.122 atm
Then, determine the amount of carbon (C) in mol by assuming that it is an ideal gas.
            n = (2.122 atm)(75 L) / (0.0821 L.atm/mol.K)(-25 + 273.15)
                                 n = 7.81 mols
The reaction is expressed as,
                        4KO2 + 2CO2 --> 2K2CO3 + 3O2
From the equation,
               (7.81 mols CO2) x (4 mols KO2/2 mols CO2) = 15.62 mols KO2
