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?
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.

Explanation:
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.
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)
Select all of the compounds.

Describe how fossil fuels are converted into usable energy
:)
Answer:
Fossil fuel power plants burn coal or oil to create heat which is in turn used to generate steam to drive turbines which generate electricity.
Explanation:
Fossil fuels are used in power plants to make steam. Steam drives turbines which coupled to generator produce electrical energy. Electrical power is used in all industries, domestic used where energy is needed.
petroleum products like oil, gas are used in motor vehicles, ships, airplanes. They burn and give the power for transport.
Fossil fuels are burned under different conditions in engines, boilers, etc which produce heat energy and then converted into mechanical energy.
gas and oil are used to heat homes.
Answer: HEY HAVE A GREAT DAY
fossil fuels are converted into usable energy by first collecting, and then I'm pretty sure its turned into gas and turns turbines.
Explanation:
Fossil fuel are energy buried within the earth that could used as energy source for consumption. Most sources of earth's energy comes from fossil fuels
