Answer: C
Step-by-step explanation: not enough information
1 km = 0.621 mi
5 km = 3.105
All you need is to do is 5 x 0.621
Step-by-step explanation:
Since Ca(OH)2 is Basic, we need to find pOH:
pOH = - log [OH-]
pOH = - log(0.0001)
pOH = - ( - 4)
pOH = 4
Since, pH + pOH = 14
Therefore,
pH of 0.0001M sol. of Ca(OH)2 = 10
The correct option is b. No, it is not a rectangle because the sides of the parallelogram do not meet at right angles.
<h3>How to explain the information?</h3>
