The Universal Space Agency wants to know the results of your Sim investigation. Write your report to the lead chemist, explaining why drops of liquid water appeared on the outside of the cold, but not the warm, soda can. Use evidence from your investigation in your explanation.

Answers

Answer:

due to warm temperature

Explanation:

Explanation:

There is water present in liquid form instead of liquid nitrogen on the outer side of the can because of the temperature present in the surrounding environment. The temperature around the can is little warm which is favourable for the water but not for the liquid nitrogen. The liquid nitrogen present in liquid state when the temperature of the surrounding is too cold. if it is warm, the liquid nitrogen starts boiling and converts into gaseous state so that's why the warmer temperature is responsible for the presence of water not the liquid nitrogen.

The boiling point of a liquid is tested at 10 different pressures, from 0.5 to 1.4 atmospheres. The results of the tests show that
there is a nearly constant increase in boiling point for each increase in pressure. Which conclusion is reasonable based on this
information? (1 point)

O A boiling point at 1.5 atmospheres could not be predicted with any certainty at all.
O A boiling point at 15 atmospheres could not be predicted with any certainty at all.
O A boiling point at 1.5 atmospheres could be predicted fairly well.
O A boiling point at 15 atmospheres could be predicted fairly well.

Answers

Since the increase in boiling point with increasing pressure is fairly constant, then, the boiling point at 1.5 atmospheres could be predicted fairly well.

We say that a substance has reached its boiling point when its pressure equals the atmospheric pressure. Recall that we can be able to make predictions from the results of an experiment.

In this case, we are told that there is a nearly constant increase in boiling point for each increase in pressure. Therefore, it is reasonable to conclude that, a boiling point at 1.5 atmospheres could be predicted fairly well.

17) An ethanol solution has a concentration of 0.500M. What volume in liters of this solution
would contain 8.0 moles of ethanol?

Answers

Examples:Convert 750 mL to liters:

Liters of solution = mL of solution x (1 L/1000mL)

Liters of solution = 750 mL x (1 L/1000 mL)

Liters of solution = 0.75 LThe Answer:Divide the mass of the solute by the total volume of the solution. Write out the equation C = m/V, where m is the mass of the solute and V is the total volume of the solution. Plug in the values you found for the mass and volume, and divide them to find the concentration of your solution.

To calculate the Molar Concentration, we will find the molar concentration by dividing the moles by liters of water used in the solution. For example, the acetic acid here is completely dissolved in 1.25 L of water. Then divide 0.1665 moles by 1.25 L to get the molar concentration, which will be 0.1332 M.

Explanation:

Answer: 0.613 moles

Explanation: To convert from grams to moles, you have to use the molar mass provides on the periodic table. The molar mass of lead is 207.2 g/mol. To find the moles, we need to divide the grams of lead by the molar mass. 127/207.2 is equal to about 0.613 moles.

To balance a redox reaction, what must be done?

The ion charge on both sides of the equation must equal zero.

Water must be added to both sides of the equation.

The increase and decrease in oxidation numbers must be balanced.

H+ and OH− must be added to opposite sides of the equation.

Answers

To balance a redox reaction, the increase and decrease in oxidation numbers must be balanced.

A redox reaction also called an oxidation- reduction reaction is a chemical reaction in which there is simultaneous gain and loss of electrons.

The species that loses electrons gets oxidized while the species that gains electrons gets reduced. This results in a change of oxidation number. The species that gets reduced decreases in oxidation number and the species that gets oxidized increases in oxidation number.

So, to balance a redox reaction, the simultaneous gain and loss of electrons must be balanced.

Thus, to balance a redox reaction, the increase and decrease in oxidation numbers must be balanced.
