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]

<em>I am going to use first-person pronouns for this drop of water</em>

[ 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! - <u>Please note this is very simplified</u>

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

5K + KNO3 ------ 3K2O + N
masya89 [10]

Answer:

174,957.143 grams of potassium and 89,228.478 grams of potassium nitrate will be needed.

Explanation:

5K +KNO_3\rightarrow 3K_2O + N

Mass of nitrogen =  27 lbs = 12,247 g

1 lbs = 453.592 g

Moles of nitrogen = \frac{12,247 g}{14 g/mol}=874.786 mol

According to reaction, 1 mole of nitrogen is produced from 5 moles of potassium and 1 mole of potassium nitrate.

Then 874.786 mol of nitrogen will be obtained from :

\frac{5}{1}\times 874.786 mol=4,373.928 mol of potassium.

Then 874.786 mol of nitrogen will be obtained from :

\frac{1}{1}\times 874.786 mol=874.789 mol of potassium nitrate.

Mass of 4,373.928 moles of potassium:

4,373.928 mol\times 40 g/mol=174,957.143 g of potassium

Mass of 874.789 moles of potassium nitrate:

874.789 mol\times 102 g/mol=89,228.478 g of potassium nitrate

Korvikt [17]
Moving the electron away from the nucleus requires energy, so the electrons in the outer shell will have more energy than ones in the inner shell. Electrons always have a charge of -1, so the charge in the inner and outer shell will be the same. Therefore the answer is 3
