Can someone please explain the cause and effect between the rearrangement of atoms and molecules in a chemical reaction and the different properties that the products have from the reactants.

Answers

Answer:

In a chemical reaction, the atoms and molecules that interact with each other are called reactants. ... No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.

EASYYYYYYYYYYY A batter hits two balls during practice. Ball A travels 10 meters, while ball B travels 12 meters. The batter decides to hit ball A with less force. How will this change the motion of ball B?

The motion of ball B will increase.
The motion of ball B will decrease.
The motion of ball B will stay the same.
The motion of ball B will become the same as ball A.

Answers

Answer:

The motion of ball B will increase

Explanation:

Because if you hit ball A with less force than ball B then that means that ball B will go faster because you had hit ball A will less force witch will not be as faster as ball B.

When vinegar, an acid, is mixed with baking soda, a base, the reaction is similar to the reaction of Alka-Seltzer and water; a salt, water and carbon dioxide are produced. In two or more complete sentences, describe how your knowledge of balancing chemical equations can help you to determine the missing compound.


NaHCO3 + HC2H3O2 ⟶ ________ + H2O + CO2

Answers

Answer:

1) Carbon dioxide is the name of the gas.

2) The missing compound is  

Step-by-step explanation:

1)When ever an acid reacts with baking soda brisk effervescence of carbon dioxide gas are released.

So, when citric acid reacts with baking soda it gives salt of sodium citrate , water and carbon dioxide gas.

2)

According to law of conservation of mass:

Number of atoms on reactant sides are equal to the number of atoms on product side.

Number of atoms of an element on left hand side is equal to the number of atoms of that same element on the right hand side.

Number of hydrogen atom on reactant side = 5

Number of hydrogen atom on product side = 2+ x

5 = 2+x

x = 3

Number of carbon atom on reactant side = 3

Number of carbon atom on product side = 1 + y

3 = 1 + y

y = 2

Number of oxygen atom on reactant side = 5

Number of oxygen atom on product side = z + 3

5 = z + 3

x = 2

Number of sodium atom on reactant side = 1

Number of oxygen atom on product side = a

1 = a

The missing compound is  

Explanation:

Answer:

1) Carbon dioxide is the name of the gas.

2) The missing compound is H3C2O2Na

If you need an explanation, please ask. I hope this helps! :)

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

The answer is B!!!!!

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!
