When should a line graph be used

olga_2 [115]

Answer:

<em>Line graphs are used to track changes over short and long periods of time. When smaller changes exist, line graphs are better to use than bar graphs. Line graphs can also be used to compare changes over the same period of time for more than one group.</em>

DanielleElmas [232]

Answer:

118.75°C is the boiling point of a solution.

Explanation:

Mass of the solute that is barbiturates = 42.5 g

Molar mass of a solute = 184.2 g/mol

Moles of solute = $\frac{42.5 g}{184.2 g/mol}=0.2307 mol$

Mass of the solvent that acetic acid = 825 g = 0.825 kg

$molality=\frac{\text{Moles of solute}}{\text{Mass of solvent}}$

Molality of the solution (m):

$m=\frac{0.2307 mol}{0.825 kg}=0.2796 m$

Elevation in boiling point is given as:

$\Delta T_b=i\times K_b\times m$

i = 1 (organic compound)

$=1\times 3.07^oC/m\times 0.2796 m=0.8585^oC$

$\Delta T_b=T_b-T$

$T_b$ = Boiling temperature of solution.

T = boiling temperature of solvent that is acetic acid=117.9°C

$0.8585^oC=T_b-117.9^oC$

$T_b=118.75 ^oC$

118.75°C is the boiling point of a solution.

Which flowers are prettier, daisies or roses?

zhenek [66]

Overall, it depends on your opinion. Some people think roses are prettier than daisies, and daisies are prettier than roses.

Roses are the definitive symbol for love and appreciation, while daisies are a symbol of Virgin Mary representing her chastity, grace, and purity. Daisies represent beauty and patience as well.
