B) the mass of the reactant equals the mass of the product.
I don't see an image, but the force of gravity depends on mass and distance. If the mass and the distance are different, you divide (mass÷distance).the greater the number the greater the force of gravity.
Tell me if you need more info.
These balloons will be attracted, as you have shown in the picture, there are two positives, they are not in the same spot. when two of the same poles are put together, they rebel each other, since the two positive poles are not in the same area of the balloon, the balloons will attract each other. I hope this helps :)

Explanation:
<u>Functions</u>
When one magnitude depends on other (or others), we usually try to express them as a function which can contain any number of variables, constants, and operations.
The area of a circle is computed by the well-known formula

We are required to use function notation to express the area of a circle f(r) in terms of the radius r. If the radius is in cm, then the area is in
.
The required function is

For a radius of 4.3 cm:


One watt is defined as the energy consumption rate of one joule per second. 1W = 1J / 1s. One watt is also defined as the current flow of one ampere with voltage of one volt.
