"The water becomes warmer."
<u>Remember</u>: Kinetic energy means how much, on average, a molecule is moving around. This is directly translated into heat. Therefore, the higher the kinetic energy, the more heat produced.
Answer:
Neutral atoms can be turned into positively charged ions by removing one or more electrons. ... Atoms that gain extra electrons become negatively charged. A neutral chlorine atom, for example, contains 17 protons and 17 electrons. By adding one more electron we get a negatively charged Cl- ion with a net charge of -1.
The process that is responsible for the greatest loss of energy from the Earth's surface into space on a clear night is called radiation.
Answer:
5.2 moles of KClO₃ are needed
Explanation:
Given data:
Number of moles of potassium chlorate needed = ?
Number of moles of O₂ formed = 7.8 mol
Solution:
Chemical equation:
2KClO₃ → 2KCl + 3O₂
now we will compare the moles of KClO₃ and O₂.
O₂ : KClO₃
3 : 2
7.8 : 2/3×7.8 = 5.2
5.2 moles of KClO₃ are needed.
