4. A student purified a 500-mg sample of phthalic acid by recrystallization from water. The published solubility of phthalic aci

kupik [55]

Answer:

2.77 mL of boiling water is the minimum amount which will dissolve 500 mg of phthalic acid.

Explanation:

We know from the problem that 18 g of phthalic acid are dissolved in 100 mL of water at 99 °C.

Now we devise the following reasoning:

If 18 g of phthalic acid are dissolved in 100 mL of water at 99 °C

Then 0.5 g of phthalic acid are dissolved in X mL of water at 99 °C

X = (0.5 × 100) / 18 = 2.77 mL of water

When 40 grams of ammonium nitrate explode 14 grams of nitrogen and 8 grams of oxygen form. How many grams of water form

DerKrebs [107]

Answer:

18 grams of water

Explanation:

The Balance Chemical Reaction is as follow,

2 NH₄NO₃ → 2 N₂ + O₂ + 4 H₂O

According to Equation,

160 g (2 moles) NH₄NO₃ produces = 72 g (4 moles) of H₂O

So,

40 g of NH₄NO₃ will produce = X g of H₂O

Solving for X,

X = (40 g × 72 g) ÷ 160 g

X = 18 g of H₂O

A wooden boat discovered just south of the great pyramid in egypt has a carbon-14>carbon-12 ratio that is 72.5% of that found

Kazeer [188]

The half life for C14 is 5730 years.

We assume that Carbon 14/ Carbon 12 ratio was steady for living organisms over time, the problem is actually telling us that
$\frac{Nt}{N0}$ = 0.0725 = $\frac{1}{2}$ ˣ

Take the natural logarithm and In on both sides.
ln(0.725) = ln $\frac{1}{2}$ ˣ
= - 0.3216 = xln ( $\frac{1}{2}$ = -0.6931x.
So x = (-.3216) / (-0.6931) = 0.464
or

t/t₁/₂ = 0.464
So t = 0.464 x t₁/₂ = 0.464 * 5730 yrs = 2660 years.
