Answer:
Explanation:
The human body is constantly radiating heat to its surroundings, and human comfort is closely tied to the rate of this radiation we need to know this because its part of a daily life.
Answer:
Explanation:
The concept applied is the conductivity as it relates to the dissociation and the number of ions in solution. BaCl2 and KBr are ionic solids that will dissociate completely in water to give trivalent and divalent ions respectively.
Benzoic acid on the other hand is a weak acid as such it will not dissociate in water. sugar is a covalent compound.
Hence BaCl2 will have the highest conductivity based on the aforementioned reasons, then followed by KBr ; BaCl2 > KBr > C6H5COOH > C6H12O6
We use the the dilution equation expressed as
M1V1 = M2V2
where the terms with subscripts of one represent the initial conditions for the concentrated solution while the terms with subscripts of two represent the final conditions for the diluted solution.
Rearranging the dilution formula to calculate for the molarity M2 of the diluted solution
M2 = M1V1 / V2 = (0.80M * 0.225L) / 1.0L = 0.18 M
