The Answer is option B.
pH is a scale for measuring either the solution is acidic or basic or neutral. In another way we can also say that pH is the measurement of concentration of hydrogen ions.
when we see the relationship between the hydrogen ions and pH, we see they are inverse relationship means if pH is low, the solution has greater hydrogen ions. So as the pH value increases the amount of hydrogen ions decreases.
That is the reason lemon juice with pH 2 has greater number of hydrogen ions.
The molar mass of is 86.02 g/mole
.
<h3><u>
Explanation:</u>
</h3>
The molar mass of a chemical compound is represented as the mass of a unit of that compound separated by the number of substances in that unit, measured in moles. The molar mass is a volume, not molecular, the property of a substance.
The molar mass is a percentage of various examples of the compound, which usually change in mass due to the appearance of isotopes.
From the below attached table, the Molar mass of is 86.0108 g/mol.
Answer:
Explanation:
We shall apply Arrhenius equation which is given below .
K₂ and K₁ are rate constant at temperature T₂ and T₁ , Ea is activation energy .
Putting the given values
T₂ = 335.27 K
= 62.27 °C
Answer:
Waters' boiling point decreases with increases in elevation because of the atmospheric pressure.
For example, the higher in elevation you are. The lower the atmospheric pressure is. In other words heated water reached boiling point quicker.
Answer:
60 kilometres per hour is the slowest rate of travel
Explanation:
we convert
20 kilometer per minute into kilometer per second
it comes out 1/3 kilometer per sec
