If the speedometer in a car reads 78 miles per hour, the car's speed in kilometers per hour is 125.53 kilometers per hour.
<h3>How to convert speed?</h3>
The speed of a car is the measure of the distance moved over a given period of time, hence, it is measured in miles/hour, km/hr, m/s etc.
According to this question, the speedometer in a car reads 78 miles per hour.
Since the conversion factor of kilometers per hour and miles per hour is as follows:
1 kilometer per hour = 0.62 miles per hour
Then, 78 miles per hour = 125.53 kilometers per hour.
Therefore, if the speedometer in a car reads 78 miles per hour, the car's speed in kilometers per hour is 125.53 kilometers per hour.

I hope this helps ya!
The concentration of the basic solution is determined by:
N = (number of moles / volume of solution)
number of moles = 1.09 x 10^-2 mol
volume of solution = 1 liter
N of basic solution = 1.09 x 10^-2 mol / 1 liter
N = 1.09 x 10^-2 mol/L
The initial concentration of Zn (OH)2 is 0; the basic solution is 1.09x10^-2 M, then the concentration of OH in the final solution is 1.09x10^-2 M
Explanation:
When an atom bonds with another atom then it results in the formation of a chemical bond.
This formation of bond could be due to transfer or sharing of electrons.
When a chemical bond is formed due to transfer of electrons then this type of bond is known as ionic bond.
When a chemical bond is formed due to sharing of electrons then this type of bond is known as covalent bond.
Metals don't form covalent bonds because of the low ionization energes of the metal atoms. It is easier for them to release electrons rather than sharing it. But this is not always the case, there are some metals that can form covalent bonds.
