Answer:
<u>CH</u>
Explanation:
Molecular formula of propene : <u>C₃H₆</u>
Take the HCF of carbon and hydrogen atoms :
Then, we can write the formula as :
- 3CH
- This means there are 3 moles present
Empirical Formula :
- Molecular Formula / No. of moles
- C₃H₆ / 3
- <u>CH</u>
<u></u>
The empirical formula of propene is <u>CH</u>
Answer:
13.79800 centimeters
hope this helps!
pls mark me as the brainliest
have a great day ahead!
To convert this first lets see how many meters are in 1 km.
1 km = 1000 meters
Now lets multiply:-
2.7 × 1000 = 2700
So, 2.7 km = 2700 meters.
Hope I helped ya!!
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⁻
