Answer:

The Answer is 'D'

Explanation:

The diagram on the down side shows the behavior of the particles of a liquid so I suppose it is the ocean. While the top diagram shows the behavior of the particles of a gas so I am sure it's the air. Therefore I chose the last diagram because it describes exactly how you wanted in the question, which is the Ocean's water evaporating to become gas or the 'air' as we say

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! :)

The table shows the densities of four samples, each of the same volume.


DENSITIES OF SAMPLES

Sample Density (g/cm3)
W 5.1
X 1.7
Y 7.3
Z 3.5

Which sample has the greatest mass?

Answers

Answer:

Its Y

Explanation:

The formula for density is D=m/v therefore the formula for mass is m=d(v) since v is a constant the sample with the highest density will also have the highest mass. Meaning that Y is the answer.

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.
