After Eris was discovered, scientists had to decide whether to count it as a planet. Why did this make them question whether Pluto should still be counted as a planet?
a
because Pluto and Eris are both space objects
b
because Pluto and Eris were discovered at the same time
c
because Pluto and Eris are very different
d
because Pluto and Eris are very similar

Answers

Answer:

After Eris was discovered, they had to decide whether Eris was a planet or not. If they decided it wasn't a planet, they had to also decide whether Pluto should be counted as a planet since Eris and Pluto were quite similar. They were the same size, and they were both part of the Kuiper Belt.

Explanation:

Planets are the celestial bodies that are not fixed. Pluto should be counted as a planet was a question as both Pluto and Eris were similar.

What are Pluto and Eris?

Pluto is now considered a dwarf planet and is found in the Kuiper belt that is present beyond the planet, Neptune. Similarly, Eris is also a dwarf planet.

Eris is the second-largest dwarf planet and is very similar to Pluto. The discovery of Eris questioned whether Pluto should be considered a planet.

Both the planets Pluto and Eris were similar in size and were part of the Kuiper Belt leading to the question of whether they should be a planet or not.

Therefore, option d. Pluto and Eris are very similar.

What is the influence of temperature on a chemical change?

Answers

Answer:

Increasing the temperature will cause chemical changes to occur faster. Decreasing the temperature, causes the particles to lose energy which causes them to move around less and slower. The less they move, the less collisions occur, and the less reactions occur between the chemicals = slower reaction rate.

A chemist is using 341 milliliters of a solution of acid and water. If 16.1% of the solution is acid, how many milliliters of acid are there? Round your answer to the nearest tenth.

Answers

We need to assume that the acid in question is a liquid (not a solid or a gas),

and we need to assume that the 16.1% is specified as 16.1% (v/v) ,

where "v/v" means volume in volume,

meaning 16.2 milliliters of that acid are contained in 100 milliliters of the solution of acid and water.

With those assumptions, the ratio of acid volume to solution volume is

x/342 = 16.1/100 , where x= number of milliliters of acid in the 342

milliliters of solution.

x/342 = 16./100 ---> x=342x16.1/100 ---> x=55 (Rounded)
