Answer:
A. the jar covers
Explanation:
An independent variable is what you, as the scientist, changes.
Depression is freezing point is a colligative property. It is mathematically expressed as ΔTf = Kf X m
where Kf = <span>freezing point depression constant = 1.86°c kg /mol (for water)
m = molality of solution = 1.40 m
</span>∴ ΔTf = Kf X m = 1.86 X 1.40 = 2.604 oC
Now, for water freezing point = 0 oC
∴Freezing point of solution = -2.604 oC
Answer:
2.77
Explanation:
pH = - log (1.70 x 10^-3) = 2.77
Answer:
there it is fella tried on ma own consciousness
