O A. That energy within matter can never be released
O B.
B. Tihin atoms will always combine to give off energy
Tuhin atoms
O c. That energy can only be converted between different forms
O D. That kinetic energy can only be converted to heat

Answers

Answer 1

Answer:

B. That energy can only be converted between different forms

Explanation:

The law of conservation of energy implies that energy can only be converted between different forms but can neither be created nor destroyed.

Energy is the ability to do work. It is very important physical quantity that is essential to all life forms.

Energy according to the law of conservation of energy is not produced neither is it destroyed.

Energy is simply transformed from one form to another.

Explain why it is advantageous that water does not evaporate quickly on earth

PLEASE HELP!!

Answers

Answer:

When the humidity is 100 percent, the air is saturated with water. Air pressure also affects evaporation. If air pressure is high on the surface of a body of water, then the water will not evaporate easily. The pressure pushing down on the water makes it difficult for water to escape into the atmosphere as vapor.

Explanation:

It is advantageous that water does not evaporate quickly on Earth because the soil and Earth water will be conserved.

What is evaporation?

Evaporation is a process by which a liquid is converted to the gaseous state.

The water on the Earth surface in liquid form is evaporated with an increase in heat.

However, it is advantageous that water does not evaporate quickly on Earth because the water on the Earth surface will be conserved i.e. available for future use.

A particular species of bird can fly for 36.0 hours straight, covering a distance of 158 miles. At this rate, how many feet does the bird travel in 43.0 min?

Answers

Answer:

16607 and 5/9 feet

Explanation:

First, let's find the how fast the bird travels in an hour. Finding the miles per hour: 158/36=79/18. Convert this to miles per minute to find the distance after 43 mins. Multiplying 79/18 by 1/60, 79/1080. Multiplying this by 43 to find the distance traveled; 3397/1080. As 1 mile is equal to 5280 feet, multiply by 5280 to find distance in feet. Once this is all done, you get 149468/9, or 16607 and 5/9 feet.

Part 1: What is the half-life of the element? Explain how you determined this.
Part 2: How long would it take 308 g of the sample to decay to 4.8125 grams? Show your work or explain your answer

Answers

1. The half-life of the element is 22 years

2. The time taken for 308 g of the sample to decay to 4.8125 g is 132 years

Definition of half-life

Half-life is simply defined as the time taken for half of a material to decay.

1. How to determine the half-life Original amount (N₀) = 45 gHalf of the original amount = 45 / 2 = 22.5 g

From the diagram, the time for 22.5 g is 22 years.

Thus, the half-life of the element is 22 years

2. How to determine the time i. Determination of the number of half-lives Original amount (N₀) = 308 gAmount remaining (N) = 4.8125 gNumber of half-lives (n) =?

2ⁿ = N₀ / N

2ⁿ = 308 / 4.8125

2ⁿ = 64

2ⁿ = 2⁶

n = 6

ii. Determination of the time Number of half-lives (n) = 6Half-life (t½) = 22 yearsTime (t) =?

t = n × t½

t = 6 × 22

t = 132 years

From what we know, we can confirm that the release of water vapor from sweat glands when we are not sweating is a process called insensible perspiration.

What is insensible perspiration?

This is a process by which we emit water in the form of vapor from our skin. This process is not to be confused with normal sweating. This happens at a near-constant rate in the human body and is not perceivable. The loss of water through this method also helps the body to maintain its homeostasis levels.

A 7.50g mass of compound A was added to 35.0g of water and it is found that the freezing point has decreased by 3.14°C. What is the molar mass of A?

Answers

This problem is providing us with the mass of an unknown compound, the mass of water it was added in and the change (decrease) in the freezing point the solution exhibited. Thus, the problem requires the molar mass of the compound, and at the end, the result turns out to be 126.7 g/mol, according to:

Freezing point depression:

In chemistry, colligative properties are used to understand how the properties of a solvent change as a solute is added, forming a solution. In this case, we can use the following formula, since the solute decreased water's freezing point:

[tex]\Delta T_m=-m*Kf[/tex]

Where the molality is the first variable for us to calculate given the other two:

[tex]m=\frac{-3.14\°C}{-1.86\°C/m} =1.69m[/tex]

Thus, since this molality is in moles of solute per kilograms of solvent (water), one can find the former by multiplying the 35.0 g of water, but in kilograms:

[tex]n=\frac{1.69mol}{kg} *35.0g*\frac{1kg}{1000g} =0.0591mol[/tex]

Finally, we compute the molar mass as required:

[tex]M=\frac{7.50g}{0.0591mol}\\ \\M=126.9g/mol[/tex]

As we assumed this solute is nonionizing.
