If we start with 8000 atoms of radium-226 how much would remain after 3200 years?
olya-2409 [2.1K]
<h3>Answer:</h3>

2000 atoms

<h3>Explanation:</h3>

We are given the following;

Initial number of atoms of radium-226 as 8000 atoms

Time taken for the decay 3200 years

We are required to determine the number of atoms that will remain after 3200 years.

We need to know the half life of Radium

  • Half life is the time taken by a radio active material to decay by half of its initial amount.
  • Half life of Radium-226 is 1600 years
  • Therefore, using the formula;

Remaining amount = Original amount × 0.5^n

where n is the number of half lives

n = 3200 years ÷ 1600 years

 = 2

Therefore;

Remaining amount = 8000 atoms × 0.5^2

                                = 8000 × 0.25

                                 = 2000 atoms

Thus, the number of radium-226 that will remain after 3200 years is 2000 atoms.

This is my chemistry worksheet. It's a new topic my teacher will barely review with us. Help please???
TEA [102]
So to balance an equation, you need to get the same amount of each type of element on either side of the --> . So you pretty much are given the subscripts in the equations and you need to add coefficients (just normal numbers) in front of any formula that needs it, keeping anything balance.
KCl_{3}  + O_{2}  -\ \textgreater \  KCl_{3}
turns into
2KCl_{3}+ 3O_{2} -> 2KCl_{3}

These coefficient numbers are the molar ratios, so 2 moles of KCl3 for every 3 moles of O2   so 1. 3:2

Then you can use these ratios of find out how many moles of one thing are needed if you are given the amount of another.
\frac{moles of element 1}{cofficient 1}  =  \frac{moles of element 2}{cofficient 2}
and use cross multiplication to solve for whatever you don't know

Calculate the frequency of light having a wavelength of 425nm. remember that 1nm=1×10−9m
Gnom [1K]

The frequency of light having a wavelength of 425nm will be 70588 × 10^{14} Hz.

The count of times an event takes place per unit of time is known as its frequency. The word frequency would be most frequently used to describe waves in physics including chemistry, including light, sound, including radio waves. The frequency refers to the number of times during one second that a point on a wave crosses a fixed reference point.

A waveform signal that is carried in space or down a wire has a wavelength, which is the separation between two identical places  in the consecutive cycles.

Given data:

wavelength = 425nm = 425 * 10^{-9} m

Frequency can be calculated by using the formula;

Frequency =  speed of light / wavelength

Frequency = 3 × 10^{8} m/s / 425 × 10^{-9} m = 7,0588 × 10^{14} Hz.

Therefore, the frequency of light having a wavelength of 425nm will be 70588 × 10^{14} Hz.

To know more about  frequency
