Answer:
Explanation:
we know that number of moles=mass(in grams)/molar mass
for the mass of oxygen the equation becomes
mass=number of moles*molar mass
Fusion and Fission both are nuclear reactions where the major difference between them is Fusion is combining process whereas fission is a breaking process.
<u>Explanation:</u>
<u>Similarity:</u>
Both Fission and Fusion are nuclear reactions that releases vast amount of energy.
<u>Difference:</u>
- Fission is the splitting of heavier nucleus into lighter nuclei which generates maximum amount of energy whereas fusion is the combining 2 lighter nuclei to form a heavier nucleus and makes a vast energy.
- The energy generated by fission reaction in these reactors heats up the water into steam. This steam is utilized to rotate a turbine to generate carbon-free electricity.
- Fusion reactions are difficult to retain for longer period of time since it needs tremendous amount of temperature and pressure to combine the nuclei together.
Answer:
An acid is substance that produces <u>H⁺ </u>ions in solution, which is also written as the hydronium ion <u>H₃O⁺</u>. A base is a substance that produces an ion with the formula <u>OH⁻ </u>and the name <u>hydroxyl</u> ion.
Explanation:
An acid is substance that produces H⁺ ions in solution, which is also written as the hydronium ion H₃O⁺. A base is a substance that produces an ion with the formula OH⁻ and the name hydroxyl ion.
Acid:
An acid is the substance that sour in taste and turns the color of litmus paper from blue to red.
pH of acid is less than seven.
Base:
An acid is the substance that bitter in taste and turns the color of litmus paper from red to blue.
The pH of base is 7-14.
Arrhenius gives the simplest definition of acid and base.
Arrhenius acid:
A substance that increase the concentration of hydronium ion in solution is called acid.
HNO₃ → H⁺ + NO₃⁻
(H₂O)
Arrhenius base:
A substance that increase the concentration of OH⁻ ion in solution is called base.
KOH → K⁺ + OH⁻
