Given :
The half-life of carbon 14 is 5,730 years.
To Find :
How much would be left of an original 50-
gram sample after 2, 292 years.
Solution :
We know, rate law for first order reaction is given by :
...1)
Here, is initial amount and is final amount.
And
Putting value of half time in above equation, we get :
Putting value of k in equation 1) , we get :
Hence, this is the required solution.
Answer:
Step-by-step explanation:
When we solve for an equation, our goal is to find the value of the variable. Any variable can be used, but for the time being let’s assume we use .
We can algebraeically solve equations until we get the value of x - in which we will have x equal to something.
Say we have the equation . Our goal is to find the value of . <u>We can do this by getting x isolated on one side so we have something equal to x</u>.
We can subtract 5 from both sides and divide both sides by 5.
We now know the value of since it’s on one side of the equation.
Hope this helped!
Answer:
<em>
The slope is 2/5</em>
Step-by-step explanation:
<u>Calculating the Slope of a Line
</u>
Suppose we know a line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
We are given the points (-5, -2) (5, 2). Let's compute the slope:
Simplifying:
The slope is 2/5
I am not sure
The answer is 97
