Answer:
11·699
Explanation:
Given the concentration of hydroxide ion in the solution is 5 ×
M
Assuming the temperature at which it is asked to find the pH of the solution be 298 K
<h3>At 298 K the dissociation constant of water is

</h3><h3>∴ pH + pOH = 14 at 298 K</h3><h3>pOH of the solution = -log( concentration of hydroxide ion )</h3>
∴ pOH of the given solution = - log(5 ×
= -0·699 + 3 = 2·301
pH of the given solution = 14 - 2·301 = 11·699
∴ pH of the solution = 11·699
Answer: The given compound is 1-butene.
Explanation:
In simple hydrocarbons, if there are only single bonds present then the suffix "ane" is added to the name of hydrocarbon.
If there is a double bond then suffix "ene" is added to the name.
If there is a triple bond then suffix "yne" is added to the name.
For example,
has one double bond which is at position 1 and there are four carbon atoms present.
Hence, name of this compound is 1-butene.
Hey there!
Ca + O₂ → CaO
Balance O.
2 on the left, 1 on the right. Add a coefficient of 2 in front of CaO.
Ca + O₂ → 2CaO
Balance Ca.
1 on the left, 2 on the right. Add a coefficient of 2 in front of Ca.
2Ca + O₂ → 2CaO
Our final balanced equation: 2Ca + O₂ → 2CaO
