If there is less ionization energy does that mean that it is more reactive? Why?
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.
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.

Zinc chloride (ZnCl2) is used as a flux when joining metals. It also is used to fireproof and remove odor from clothing. Reacting the metal zinc (Zn) with hydrochloric acid (HCl) to produce zinc chloride and hydrogen (H2). Use the models above to demonstrate that mass is conserved when zinc reacts with hydrochloric acid.
Answer:
The atoms are just rearranged but there is no decrease or increase in the mass. A law fo conservation.
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.

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.
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.
