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.

Given the reaction: 4A1 + 302 - 2A1,O, How many grams of Al will be
dlinn [17]

Answer:

The answer to your question is 27 g of Al

Explanation:

Data

mass of Al = ?

moles of Al₂O₃ = 0.5

The correct formula for the product is Al₂O₃

Balanced chemical reaction

               4Al + 3O₂   ⇒   2Al₂O₃

Process

1.- Calculate the molar mass of the product

Al₂O₃ = (27 x 2) + (16 x 3)

         = 54 + 48

         = 102 g

2.- Convert the moles of Al₂O₃ to grams

               102 g ---------------- 1 mol

                 x       ----------------  0.5 moles

                 x = (0.5 x 102) / 1

                 x = 51 g of Al₂O₃

3.- Use proportions to calculate the mass of Al

                4(27) g of Al --------------- 2(102) g of Al₂O₃

                     x               --------------- 51 g

                        x = (51 x 4(27)) / 2(102)

                        x = 5508 / 204

                        x = 27 g of Al

Explain how the concentration of hydronium ions and hydroxide ions are related to pH.
Dominik [7]
Hello!

The concentration of hydronium ions is related to pH by the following simple equation:

pH=-log[H_3O^{+}]

From this equation, you can see that as the hydronium concentration is higher, the pH will be lower.

The concentration of the OH⁻ ions is related to the pH by the following set of equations

pOH=-log[OH^{-}] \\ pH=14-pOH

You can see that as the concentration of OH⁻ is higher, the pOH is lower and thus the pH is higher. 

When the pH of the solution is less than 7, the solution is acidic.

When the pH of the solution is higher than 7, the solution is basic.

Have a nice day!
