The ideal gas equation is pV = nRT

From that you can derive several equations, depending on which variables are fixed.

1) When n and T are fixed:

pV = nRT = constant

pV = constant => p1 V1 = p2 V2 => p1 / V2 = p2 / V1 ---> Boyle's Law

2) When n and V are constant:

p / T = nR/V = constant

p / T = constant => p1 / T1 = p2 / T2 ----> Gay - Lussac's Law

3) when n and p are constant

V / T = nR/p = constant

V / T = constant => V1 / T1 = V2 / T2 ---> Charles' Law

4) When only n is constant

pV / T = nR = constant

pV / T = constant => p1 V1 / T1 = p2 V2 / T2 ----> Combined gas law.

There you have the four equations that agree with the ideal gas law.

The figure shows the skeletal structure in line-angle (line-bond) mode of 2,5-dimethylhexa-1,4-diene. Identify the number of

deff fn [24]

Answer:

There are 22 hydrogen in 2,3,3,5-tetramethylhexane (C10H22)

From the left to the right of the skeletal structure:

1st Main Carbon = 3 hydrogen

2nd Main Carbon = 1 hydrogen

1st Branch Carbon = 3 hydrogen

3rd Main Carbon = 2 hydrogen

2nd Branch Carbon = 3 hydrogen

3rd Branch Carbon = 3 hydrogen

4th Main Carbon = 0 hydrogen

4th Branch Carbon = 3 hydrogen

5th Main Carbon = 1 hydrogen

6th Main Carbon = 3 hydrogen

Total = 22 hydrogen

Explanation:

This is the skeletal formula for 2,3,3,5-tetramethylhexane - the 2D chemical structure. It is an organic compound. The carbon atoms in the structure are known as the carbon backbone. The hydrogen atoms are linked to the carbon backbone. This provides each carbon atom with four bonds.

How to convert butanoic acid to propanamide?

netineya [11]

Butanoic acid is converted to propanamide by first converting it to propanoic acid, then ammonium propanoate and then finally propanamide by heating.

<h3>How are carboxylic acids converted to amides?</h3>

Carboxylic acids are converted to amides by converting them into into an ammonium salt which then produces an amide on heating.

The ammonium salt is prepared by adding ammonium carbonate to an excess of the acid. The ammonium salt is then heated to give the amide

Therefore, butanoic acid is converted to propanamide by first converting it to propanoic acid, then ammonium propanoate and then finally propanamide by heating.

In conclusion, carboxylic acids are converted to amides in two steps.

Horned animals have different sizes of horns. The size of their horns can affect their ability to

Fofino [41]

Answer:

survival of fit individuals

Explanation:

I believe its survival of fit individuals because the animals with different horns are going to be able to find a mate or provide better depending on their horn and its kind of like natural selection in the sense those who have genetically better (??) horns are more likely to survive. Hope it helps but it might be a little bit of a confusing explanation.

How many different flame colors were you able to detect? How many different elements must have been exposed to the flame to prod

Bogdan [553]

Answer:

This question is incomplete

Explanation:

This question is incomplete, however, there are some basic things that be used to answer the completed question on your own. Flame test is a test that is used to identify metal ions in a compound. Although, not all metal ions produce a colour in a flame test.

In a flame test, a "clean wire loop" is dipped in an unknown solid/mixture of solids, the loop where the solids must have attached to is then placed in the tip of a blue flame (perhaps of a bunsen burner). A colour change/changes is then observed during the course of this process. Some popular metal ions and there colour in flame test are listed below

Lithium ion ⇒ red

Sodium ion ⇒ yellow

Potassium ion ⇒ lilac

Calcium ion ⇒ orange-red

Barium ion ⇒ pale-green

Copper ion ⇒ blue-green

rubidium ion ⇒ red-violet

Lead ion ⇒ gray white

The number of different colours observed will ultimately determine the number of elements exposed to the flame
