What is the activity of a 54.7 μCi sample of carbon-14 in becquerels?

Chemistry

Alexus [3.1K]3 years ago
8 0
To calculate the activity of carbon-14 in becquerels, we need a conversion factor to multiply to the value given above. Base on my research, I found that <span>1 Ci = 3.70x10^10 Bq. We convert as follows:

</span>54.7 μCi = 54.7 x 10^-6 Ci ( 3.70x10^10 Bq / 1 Ci ) = 2.02 x 10^6 Bq

Hope this answers the question. Have a nice day.

What is the [H3O+] if the [OH-] is 1 x 10 -8?
Tanzania [10]

From the calculation, the concentration of the oxonium ions is 1 * 10^-6 M

<h3>What is concentration?</h3>

The term concentration refers to the amount of substances present in the solution. There are several units that can be used to show the concertation of a substances such as moles/liter, gram per liter, parts per billion, parts per billion, percentage etc.

Now we know that water is composed of the hydrogen and the hydroxide ions and the product of the both is generally known as the ion product of water and have a value of 1 * 10^-14.

If that be the case, we are in order to write the expression;

[H3O+]  [OH-] = 1 * 10^-14

[H3O+] = 1 * 10^-14/ [OH-]

[H3O+] = 1 * 10^-14/ 1 x 10^ -8

[H3O+] = 1 * 10^-6 M

If the oxidation state of H is +1 and O is -2, what is the oxidation state of C in C2H4O?
Sedbober [7]

Answer:

-1

Explanation:

According to this question, the oxidation state/number of H and O in C2H4O is +1 and -2 respectively.

The oxidation state of carbon in the compound can be calculated thus:

Where;

x represents the oxidation number of C

C2H4O = 0 (net charge)

x(2) + 1(4) - 2 = 0

2x + 4 - 2 = 0

2x + 2 = 0

2x = -2

Divide both sides by 2

x = -1

The oxidation number of C in C2H4O is -1.
