What is the final concentration if 50.0 ml of a 2.00 m solution are diluted to 500.0 ml??
laila [671]
In order to calculate the final concentration of a dilution, it is important to memorise and remember the following equation:

C1V1/C2V2
Where: 
C1 = Initial concentration
V1 = Initial volume
C2 = Final concentration
V2 = Final volume

We are given three of the four, and we are asked to calculate the final concentration in moles, so we may substitute these given values into our equation as follows:

C1V1 = C2V2
(2.00m)(50.0 mL) = (C2)(500mL)
100 = C2(500mL)
C2 = 0.2 m

In the final step, we simply divide 100 by 500 to get our final concentration value.

Carbon-14 undergoes radioactive decay in the reaction above. Determine the type of radiation emitted in this reaction and descri
Drupady [299]

<u>Answer:</u> The beta-particle is being released in the reaction and the nucleus is changing from to nitrogen.

<u>Explanation:</u>

Carbon-14 undergoes a radioactive decay by the process of beta-minus decay.

In beta-minus decay, a neutron gets converted to a proton and an electron.

The equation for the beta-minus decay of carbon-14 follows the reaction:

_6^{14}\textrm{C}\rightarrow _7^{14}\textrm{N}+_{-1}^0\beta

In this reaction beta-particle is being released carrying -1 charge. Another name for this particle is known as electron.

In this decay process, the nucleus is changing from carbon to nitrogen. The property of the nucleus is changing completely as number of protons is getting increased.
