Charle's law states that at constant pressure, absolute temperature and volume are proportional. Mathematically,

V ∝ T. T, the temperature, is quoted in Kelvins.

Explanation:

Given the proportionality, V1T1 = V2T2. V2 is unknown but V2 = T2×V1T1

Remember, that this assumes a constant pressure. Charles' law is also the reason that we can fly hot air balloons. The experiment has doubled the temperature, so how will volume evolve? Will it get bigger, smaller, remain the same?

Which one of the following is smallest in size

mario62 [17]

F- is the smallest because it accepts 1 electron 2 make its atomic number 10 making it have jst 2 orbitals but O²-,N³- and Na have their atomic number to be 18,17 and 11 respectively with 3 orbitals..
hope this helps *winks*

According to the following equation:

Volgvan

2H2 + O2 → 2H2O
2 mol. → 2×(1×2+16)
1 mol. → x
$x = \frac{36 \times 1}{2 } = 18 \: g \: \: of \: h2o$

Imagine that you are a drop of water in the ocean. Describe a journey through the water cycle. Explain what causes you to change

Scorpion4ik [409]

I am going to use first-person pronouns for this drop of water

[ Start ] Liquid

I start out as a drop of water among other drops of water in the ocean. I am currently a liquid as I can change shape easily but I do not float up.

[ Middle ] Gas

The sun feels very hot. From the heat I turn into a gas, specifically water vapor, and float up into the sky.

[ Middle x 2 ] Solid

In the sky I meet up with a lot of my past friends. We form a cloud, and as we grow heavier (the more the merrier) we start to fall down. It is extremely cold now, so we fall down as a solid, also known as hail or snow.

[ End ] Liquid

We hit the ocean again as we fall from the sky. I'm so happy to be back home as a water drop again!

Have a nice day! - Please note this is very simplified

I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

The skeletal structure in line-angle (line-bond) mode of 2,3,3,5-tetramethylhexane is shown. Identify the number of hydrogen ato

Kruka [31]

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.
