Answer: the boiling point is = 137.325°C
Explanation:
From the formula: ∆Tb= Kb*m
From the question, Kb= 0.95, m= 27.5, T1= 111.2°C
Substitute into ∆Tb= Kb*m
∆Tb= 0.95*27.5= 26.125
∆Tb= T2-T1
Hence
T2- 111.2=26.125
T2= 26.125+ 111.2= 137.325°C
The answer would be c as the cart is not in motion therefor ruling out kinetic and it is completely at rest making all of it energy potential
substance is matter of particular or definite chemical constitution ex: iron, methane
mixture are two or more substances that have been combined to retain their individual chemical characteristics ex: salt water, cola
It is a compound because a compound is two or more different elements chemically combined.
Oxygen and selenium both have 6 valence electrons. They're in the same group hope this helps
