Balance the equation:

Answer:

490.83 oK

Explanation:

First of all, we better agree on the meaning of the word adiabatically. It means without the loss or gain of heat. So nothing is given up to or taken from the environment.

This also assumes that no change has occurred in the pressure.

T1 = 310 oK

T2 = ?

V1 = 12 L

V2 = 19 L

T1/V1 = T2/V2

310 / 12 = x/19            Multiply both sides by 19

310*19 / 12 = T2         Multiply 310 * 19 on the left.

5890 / 12   = T2         Divide by 12

490.83 = T2

Answer:

C) creating a relationship between mass and volume

g/L

g or gram is mass

L or Litres is for volume

Answer:

I think 1, 4, and 5 are the answers to this question. I am not sure about 4 though.

Explanation:

You have to have a power source (1), you also have to have a way to get that power somewhere else (5), and the reason for 4 would be that the power has to come back through the power source to remain working.

Explanation:

Labor unions arose in the nineteenth century as increasing numbers of Americans took jobs in factories, mines, and mills in the growing industrial economy.

The Knights of Labor, founded in 1869, was the first major labor organization in the United States. The Knights organized unskilled and skilled workers, campaigned for an eight hour workday, and aspired to form a cooperative society in which laborers owned the industries in which they worked.

The Knights’ membership collapsed following the 1886 Haymarket Square riot in Chicago. By 1886 the American Federation of Labor (AFL), an alliance of skilled workers’ trade unions, was growing.

Answer:

100 m/ s²

Explanation:

Newton's Second Law of Motion:

[tex] \boxed{ \mathsf{force = mass \times acceleration}}[/tex]

___________________

In the question:

Note that the quantities here must be in their SI units.

SI unit of Force is Newton(N).

SI unit of mass is kilogram(kg)

Force is already in it's SI unit, while mass isn't.

Converting mass from grams to kilograms:

1000 g = 1 kg

=> 1 g = 1/ 1000 kg

=> 50 g = 50/ 1000 kg

= 1/ 20 kg

___________________

Calculating acceleration:

[tex] \mathsf{5 = \frac{1}{20} \times acceleration }[/tex]

multiplying both sides by 20:

[tex] \implies \mathsf{5 \times 20= (\frac{1}{20} \times 20)\times acceleration }[/tex]

20 on the RHS gets canceled, for it's present on the numerator as well as the denominator.

[tex] \implies \mathsf{100= acceleration }[/tex]

So, here, we got acceleration = 100 m/s².

Since, the other quantities used in the formula are in their SI units, acceleration must be in it's SI unit as well.

The SI unit of acceleration is m/s²

Answer:

High trainability allows the owner to train the dog to handle certain things--some dog can be trained as police dogs and can be taught various jobs, so high trainability is very important

When a dog is Viscous, the dog will keep people away from your house, they will be able to keep danger away and because they are viscous they will be able to handle danger.

Loud bark- A loud bark from a dog can help alert other people when there is a intruder, it makes alot of noise so they can attract attention easily.

Quiet Bark- Ideal for pet owners who do not like noise, they bark quietly so they are not a bother to work or anyone doing something.

Explanation: Based on the graph, what is the approximate half-life of the reaction shown below

Explanation:

Lift the kitten's tail. The opening just under the tail is the anus. Below the anus is the genital opening which is round in males and is a vertical slit in females. In kittens of similar size, the distance between the anus and the genital opening is greater in the male than the female.

TW: use of inapropate words*

Answer:

not enough information to tell

Explanation:

One way you can tell this difference is the distance between the cat's genitals (organs seen on the outside of the body) and the anus.  A male will have a much greater distance between the genitals and anus than females, 1/2 inch apart on a male kitten and over 1 inch apart on a male adult cat.  However, if the two are almost adjacent on a kitten or less than 1/2 inch apart on an adult, it’s a female.

I believe the answer would be titanium. Good luck on your assignment and have a happy christmas :)

(Physical or Chemical) properties of a substance can easily be observed. … (Physical or Chemical) properties can be used to identify substances. physical property. Oxygen is odorless and colorless.

Explanation:

A spectrum is a  pattern is unique to a substance and can be used identify it.

According to Max Plank, energy occurs in packets called quanta. Hence, energy is not continuous but takes on discrete values which are integer multiples of a fundamental amount.

Again, when a substance is given light energy, a characteristic fingerprint is obtained. This pattern is unique to the substance that has it. These characteristics “fingerprints” are called spectrums.

In case of a shortage in petroleum and natural gas, a company should find a way to make nylon without using natural resources.

Nylon is a very important material used in numerous applications. As a result of this, the demand for nylon as a raw material has genuinely been on the high side ever since.

However, nylon production depends on petroleum and natural gas. It is possible that there could be a shortage of these resources since they are obtained from the environment. In such cases, a company should  find a way to make nylon without using natural resources.

Explanation:

Some molecules in a substance have a high kinetic energy hence they are able to convert into vapor. These molecules exert pressure on the liquid surface.

We know that the molecules that compose matter are in constant random motion. The kinetic energy of all the molecules in the liquid are not the same. The molecules at the surface of the liquid posses more kinetic energy than the molecules below.

Answer:

Some molecules of a substance have high enough kinetic energy to vaporize. These molecules exert pressure on the substance.

Explanation:

Answer:

1. Ionic bonds result from transfer of electrons, but covalent bonds are formed by sharing.

2. Ions are arranged in a three-dimensional array (like crystals). Covalently bonded substances exist as discrete molecular units.

3. Ionic compounds often dissociate into ions in solution, but covalently bonded molecules retain their molecular identity in solution.
