PREDICT: Which do you think would be the most adhesive and least adhesive to wax paper and why do you think this?
A) oil

B) Isopropyl alcohol

C) tap water

D) soapy water

Answers

Answer 1
The answer is B!!!!!
Answer 2

Answer:

Tap water would be the least adhesive to wax paper.

Oil would be the most adhesive

Explanation:

If you get wax paper and water right now, it will repel the water. Putting wax on anything makes it water repellent. I don't know how but this is just my prediction.  

I feel like oil would be the most adhesive because oil repels water, so does wax paper. So I'd predict oil would hold onto wax paper the most.

Hope this helps!

ALSO PLEASE KEEP IN MIND THIS IS JUST MY PREDICTION

What does the conversation of mass say about the amount of atoms in the reactants compared to the products?

Answers

Answer:

the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction. If we account for all reactants and products in a chemical reaction, the total mass will be the same at any point in time in any closed system.

Answer:

[tex]\boxed {\boxed {\sf Atoms \ in \ reactants \ = atoms \ in \ products}}[/tex]

Explanation:

The Law of Conservation of Mass states that mass cannot be created or destroyed.

In a chemical reaction, this means the mass of the reactants (substances going in and being changed) must equal the mass of the products (new substances from the reaction).

In addition, the amount of atoms must stay the same. The atoms can and will reconfigure to form different compounds, but the number of atoms stays the same.

When the boat is placed on the scale, how does its weight compare to the weight of the water it displaced?

Answers

Answer: It'll be lighter than when it is put on the water.

Explanation: Cause when a boat needs to move, it usually takes water into the engine, and then propulses it bk out.

It will be lighter, as water is more heavier then others may think, a boat would weigh less since a chunk of water would most likely weigh 100 tons more.

How do matter and energy move through an ecosystem?
My scientific explanation is:

Your answer should include at least 6 complete sentences to explain the claim, evidence and reasoning.
Be sure to check your grammar and spelling.

Answers

Food chains allow energy to move through an ecosystem. For example, energy is transferred from organism to organism such as the sun gives energy to grass, grass gives energy to grasshoppers when they eat grass, mice eat grasshoppers, and snakes eat mice, eagles or bigger birds of prey eat snakes. A technique discovered by Charles Elton named energy pyramids display how energy is dispersed on a pyramid starting from producers to tertiary consumers. An example of a producer would be grass, primary consumer would be a grasshopper (herbivores), a secondary consumer would be a mouse/mice (eat herbivores), and a tertiary consumer (eat secondary consumers) would be an owl. Starting from the bottom of the energy pyramid (producers) to the top (tertiary consumers) it 10% of energy is available to travel up the pyramid. That is your scientific explanation!
