It’s name is calcium hydroxide and often it is easy to tell if something is a strong base if it has (OH) in the name.
Answer:
Option 1
Explanation:
The question is asking us what formula is used to obtain the quantity of heat added to a given mass of mercury in order to cause its temperature to change.
This quantity of heat is obtained from;
q = mcspΔT
Where;
q = quantity of heat added
m = mass of the mercury
csp= specific heat capacity of mercury
ΔT = temperature change
Answer:
The substance which responds to the change in the concentration of the hydronium ions in solution by changing its color is known as an indicator.
I would say <span>4. 40. g at 15°C because kinetic energy is related to temperature and not mass, so the lower temp would give you lower KE</span>
