Hey there!
The correct answer to your question is: Spectrum
A spectrum, by definition, is a range of colors which are produced by separating certain colors of light.
Thank you!
Answer:
COOHCOOH + 2OH⁻ ⇄ C₂O₄²⁻ + 2H₂O
Explanation:
The reaction of oxalic acid with a strong base like sodium hydroxide is the following:
COOHCOOH + OH⁻ ⇄ COOHCOO⁻ + H₂O (1)
In this first reaction, the oxalic acid loses one proton. In a second reaction with NaOH, the ion COOHCOO⁻ loses its second proton to form ion oxalate as follows:
COOHCOO⁻ + OH⁻ ⇄ C₂O₄²⁻ + H₂O (2)
The general reaction between oxalic acid and NaOH is (eq 1 + eq 2):
COOHCOOH + 2OH⁻ ⇄ C₂O₄²⁻ + 2H₂O
I hope it helps you!
<u>Answer;</u>
Matter is converted to energy
<u>Explanation;</u>
- Nuclear fission is a type of nuclear reaction in which a nuclei of an atom splits or breaks down into two or more smaller nuclei.
- It involves subdivision of heavy nucleus of an atom such as Uranium into two or more fragments which has almost the same equal mass.
- Nuclear fission is accompanied by release of large amount of energy, thus we can say that matter is converted to energy.
Answer:
compressions
Explanation:
in a longitudinal wave, particles of the medium vibrate in a direction that is parallel to the direction that the wave travels. places where particles of the medium crowd closer together are called compressions. places where particles of the medium spread farther apart are called rarefactions
