The decomposition of ammonia to the elements is a first-order reaction with a half-life of 200 s at a certain temperature. How l

Feliz [49]

Based on the half-life of the reaction, time taken for the partial pressure of ammonia to decrease from 0.100 atm to 0.00625 atm is 800 seconds.

<h3>What is the half-life of a substance?</h3>

The half-life of a substance is the time taken for half the amount of atoms present in that substance to decay.

The half-life of the reaction is 200 seconds.

After, one half-life, pressure reduces to 0.0500 atm

After, two half-lives, pressure reduces to 0.0250 atm

After, three half-lives, pressure reduces to 0.01250 atm

After, four half-lives, pressure reduces to 0.00625 atm

Time taken = 4 * 200 = 800 seconds

Therefore, time taken for the partial pressure of ammonia to decrease from 0.100 atm to 0.00625 atm is 800 seconds.

If f(x) = -3x +4 and g(x) = 2, solve for the value of x for<br>which (fx) = g(x) is true.

maksim [4K]

Answer:

$x=-\frac{2}{3}$

Explanation:

Let:

$f(x)=-3x+4\\\\And\\\\g(x)=2$

We need to know for which value of $x$ the function $f(x)$ is equal to $g(x)$ :

$f(x)=g(x)$

Therefore, we need to solve for the previous equation for $x$ :

Replacing the values of $f(x)$ and $g(x)$ :

$-3x+4=2$

Subtract 4 from both sides:

$-3x+4-4=2-4\\\\-3x=-2$

Multiply both sides by -1

$-3x(-1)=-2(-1)\\\\3x=2$

Divide both sides by 3:

$\frac{3x}{3} =\frac{2}{3} \\\\x=\frac{2}{3}$

Therefore the value of $x$ for which $f(x)=g(x)$ is $x=\frac{2}{3}$ .

Verify the result:

$-3(\frac{2}{3} )+4=2\\\\-2+4=2\\\\2=2$

A boat with a horizontal tow rope pulls a waterskier. She skis off to the side, the rope makes an angle of 15° with the forward

dsp73

Answer:

<h3>13,976.23Joules</h3>

Explanation:

Workdone by the rope is expressed using the formula;

W = Fd sin(theta)

F is the tension in the rope = 180

d is the displacement = 300m

theta is the angle of inclination = 15°

Substitute the given parameters into the formula;

W = 180(300)sin15

W = 54000sin 15

W = 13,976.23

Hence the workdone by the rope is 13,976.23Joules
