Explain how the models you developed show that when methane combines with oxygen to form carbon dioxide and water, no atoms are left over from the reaction.
Answers
Answer: the bonds in the methane and oxygen come apart, the atoms rearrange and then re-bond to form water and carbon dioxide
Explanation:^
From the law of conservation the reactant and product will be always same, that is no atom is extra added or no atom is left over.
What is law of conservation?
The Law of Conservation of Mass basically states that matter can neither be created nor destroyed.
From the reaction, we can see that left hand side are reactant and right hand side is products. In left side 1 carbon, 4 hydrogen, and 4 oxygen. Right hand side 1 carbon, 4 oxygen, 4 hydrogen.
Mathematically, we can say that- LHS = RHS
The arrow mark represent the reaction runs forward direction, methane gas combustion with oxygen to produce carbon dioxide and water.

If there is less ionization energy does that mean that it is more reactive? Why?
Answers
Answer:
The greater the ionization energy, the more difficult it is to remove an electron. The ionization energy may be an indicator of the reactivity of an element. Elements with a low ionization energy tend to be reducing agents and form cations, which in turn combine with anions to form salts.

In your own words describe some properties of energy.
Answers
Answer:
In explanation, these are the some I can think of that are basic.
Explanation:
Potential energy- Is an energy that is stored in something, like elastic. When you stretch it, you are creating potential energy.
Kinetic energy- Is an energy where something is being in motion. Like a roller coster, when you are being plunged to the bottom, you are witnessing kinetic energy!
Electrical energy- Is an energy which has to do with electric charge, like for example take a light bulb, and when you are putting it into it's place and it turns on, that is electrical energy flowing into the light bulb to turn it on.
Elastic energy- Is an energy where is you stretch elastic, you are creating energy that is compressed, and then letting it go.
This is a lot, but there are more basic ones, but I just went with the ones I thought were easy. I hope this will help you! Sorry if it doesn't help at all.

If you don’t discover a management technique to restore nutrients to your soil, what will happen to your crops? Select all that apply
A.Your vegetables will win prizes for being unusually large.
B.Anything you grow will be at high risk for pesticides and diseases.
C.Your land could stop producing vegetables altogether.
D.Your land will be worth less money.
Answers
If crops are not getting proper nutrients from soil we may have to apply fertilizers which adversely affect the soil if no nutrient is restored to soil, it will not produce vegetables and your land will be worth less money. Thus, options C and D are correct.
What are nutrients?Nutrients are ions, minerals and proteins that is very essential for living things. Without proper nutrition, the growth of both plants and animals become will be declined.
Plants needs some elements such as nitrogen, potassium, calcium, phosphorus etc. for their growth. They absorbs these ions and water from soil and distribute all over its body through channels.
If plants are getting no nutrients from the soil their will not grow and no new vegetables will be formed in such a land where there on management to restore soil nutrients.
In such situations, we have to apply fertilizers which have may bad impacts too. Hence, without nutrients the vegetables will not grow and the land will be worth less of money.

Explanation:
For my science class, we were doing Savvas too so I know the answer for this question.
According to the law of conservation of mass and as depicted in the model there are equal number of atoms of reactants and products , thus demonstrating that mass is conserved.
What is law of conservation of mass?According to law of conservation of mass, it is evident that mass is neither created nor destroyed rather it is restored at the end of a chemical reaction .
Law of conservation of mass and energy are related as mass and energy are directly proportional which is indicated by the equation E=mc².Concept of conservation of mass is widely used in field of chemistry, fluid dynamics.
Law needs to be modified in accordance with laws of quantum mechanics under the principle of mass and energy equivalence.This law was proposed by Antoine Lavoisier in the year 1789.
