GIVING BRAINIEST IS CORRECT! In a lab experiment, we break apart a tablet of Alka-Seltzer into different size pieces. We time the chemical reaction of the different size pieces, to see how long it takes. We ask, does breaking apart a tablet of Alka-Seltzer affect how long the chemical takes to finish? What would be the Independent variable in this lab?

A. The amount of water.
B. The temperature of the water.
C. The surface area of the Alka-Seltzer
D. The rate of the chemical reaction

Geothermal energy for industrial use is available almost anywhere. a.true b.false

Two metal blocks that have slightly different temperatures are placed next to one another. after five minutes, they both have lower but equal temperatures. according to the law of conservation of energy, what  most likelyhappened? energy was created inside the blocks.energy was destroyed inside the blocks.energy was absorbed into the blocks from outside the system.energy was transferred from the warmer block to the cooler block.

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.
