Heat energy required to increase the temperature of water in bathtub is 12,546,000 Joules.
<h3>What is thermal energy?</h3>
The energy contained by an object by virtue of heating is known as thermal energy.
Given is the mass of water m = 150 kg, Temperature change ΔT = (40 -20)= 20 °C
The specific heat of water Cp =4182 J/kg.°C
Heat transfer Q =m x Cp x ΔT
Q = 150 x 4182 x 20
Q = 12,546,000 J
Thus, Heat energy required to increase the temperature of water in bathtub is 12,546,000 Joules.

Hey there!
The periodic table is arranged by number of protons/electrons which is the same for all isotopes of an element. <u>A different isotope will have a different number of neutrons only, which does not qualify it for a separate space on the periodic table.</u>
I hope this helps!
1 milliliter = 1 cubic centimeter (cm^3)
Answer:
Explanation:
Let assume that 100 kg of the compound is tested. The quantity of kilomoles for each element are, respectively:
Ratio of kilomoles oxygen to kilomole nitrogen is:
It means that exists 1.499 kilomole oxygen for each kilomole nitrogen.
The empirical formula for the compound is:
