Treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Chemotherapy may be given by mouth, injection, or infusion, or on the skin, depending on the type and stage of the cancer being treated.

Percentage yield shows the amount of reactants converted into products. The percentage yield of the reaction is 51.7%.

The equation of the reaction is sown in the image attached. The reaction is 1:1 as we can see.

Number of moles of NaBr = 10 g/103 g/mol = 0.097 moles

We can obtain the mass of 3-methyl-1-butanol from its density.

Mass = density × volume

Density of 3-methyl-1-butanol =  0.810 g/mL

Volume of  3-methyl-1-butanol = 9 mL

Mass of 3-methyl-1-butanol = 0.810 g/mL × 9 mL

Mass of 3-methyl-1-butanol = 7.29 g

Number of moles of 3-methyl-1-butanol =  mass/molar mass =  7.29 g/88 g/mol = 0.083 moles

Since the reaction is 1:1 then the limiting reagent is 3-methyl-1-butanol

Mass of product 1-bromo-3-methylbutane = number of moles × molar mass

Molar mass of 1-bromo-3-methylbutane = 151 g/mol

Mass of product 1-bromo-3-methylbutane = 0.083 moles × 151 g/mol

= 12.53 g

Recall that % yield = actual yield/theoretical yield × 100

Actual yield of product = 6.48 g

Theoretical yield = 12.53 g

% yield = 6.48 g/12.53 g × 100

% yield = 51.7%

Answer:

the liquid becomes equal to the rate of condensation

Explanation:

ive come across this question before! and i think its right! :D

The vapor pressure of a liquid at a provided temperature is measured when the rate of evaporation of a liquid evolves equally to the rate of condensation.

Evaporation is the procedure by which water transforms from a liquid to a gas or vapor.

Evaporation is the primary route that water moves from the liquid circumstances around into the water cycle as atmospheric water vapor.

When a molecule around the surface absorbs adequate energy to overwhelm the vapor pressure, it will exit and join the surrounding air as a gas.

Explanation:

neutrons=117

protons=78

Answer:

Platinum has mass number 195.

The atomic number of platinum =78

so the number of protons is 78.

By using simple formulas

we can find out that how many neutrons and protons are present in an atom of platinum-195.

Mass number = neutrons + protons

195=neutrons + 78

neutrons=195-78=117

so the number of neutrons is 117.

1 mile equals 4 minutes

A boy rides his bike to his friend's house. He travels 2 miles in 8 minutes, the boy's average speed will be 0.25 meters per second (m/s).

Speed of any object is the rate of change of position in the given time of interval or given time of the unit is said to be speed an can be measured by dividing the distance traveled with the time.

A boy rides his bike to his friend's house. He travels 2 miles in 8 minutes so the speed will be,

            Speed = distance / time

             Speed = 2 miles / 8 minutes

              Sped = 0.25 meter per second (m/s)

Therefore, the average speed will be 0.25 meters per second (m/s) if the boy rides his bike to his friend's house. He travels 2 miles in 8 minutes.
