Answer:
The reason why we don't fall to the center the earth is the same reason why we don't fall to the floor when you sit down in a chair; the electrons in your body repel the electrons in the chair. More specifically, there is an electron cloud around each nucleus.
Explanation:
<h2>9. Given : P + O2 = P2O5</h2>
Balanced Chemical Equation: <u>4</u>P + <u>5</u>O2 = <u>2</u>P2O5
<u>Reactant Product</u>
P = (1) 4 | P = (2) 4
O = (2) 10 | O = (5) 10
Reaction Information
Phosphorus + Dioxygen = <u>Phosphorus Pentoxide</u>
Reaction Type: <u>Synthesis</u>
<h2>
10. Given: HCl + NaOH = NaCl + H2O </h2>
<u>Reactant Product</u>
H = 2 | H = 2
Cl = 1 | Cl = 1
Na = 1 | Na = 1

The chemical reaction is expressed as:
<span> 4KO2+2CO2→2K2CO3+3O2
</span>
We are given the amount of KO2 to be used in the reaction. This will be the starting point of our calculations. We do as follows:
0.425 mol KO2 ( 3 mol O2 / 4 mol KO2 ) = 0.319 mol O2 produced
Hope this answers the question. Have a nice day.
The larger the piece the longer it will take to break down. This is because it has more mass that needs to be broken down. Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
Particles of the substance have the most kinetic energy when the substance is(a)1. A gas. The part of the graph that represents where the substance has the least amount of potential energy is labeled(b)1. Solid.
Gas molecules have the highest average velocities among the three states of matter so gas has the highest kinetic energy. During freezing, a substance loses a lot of potential energy so solid has the least potential energy.
