Amiraneli [1.4K]

The processes of extracting and separating gold in remote regions often result in environmental contamination with Cyanide (Option B).

<h3>What is cyanide?</h3>

Cyanide is a substance that contains a group formed by Carbon and Nitrogen forming a strong chemical bond (C≡N).

Cyanide can be very toxic when forms soluble salts (e.g., sodium and/or potassium cyanide).

Cyanide was used as a chemical compound during gold extraction, thereby generating environmental contamination.

At 25oC three moles of a gas occupy a volume of 4.0 L at 1.9 kPa If the volume increases to 8.0 L what will the new pressure be?
ivolga24 [154]

Answer:

0.95 kPa

Explanation:

P_{1} V_{1} = P_{2}V_{2}

(4.0)(1.9) = (P_{2})(8.0)

P_{2}= 0.95 kPa

-- However, you should see that when the volume increases (doubles, in this case) you will divide the original pressure value by 2. Pressure and volume are inversely related.

Limit as x approaches 0 of (2e^x-2)/x
Snowcat [4.5K]

Answer:

Explanation:

\lim_{x \to \ 0} \frac{2e^x-2}{x}

So first, we have to plug in zero and see if we can evaluate this limit simply from that.

When we plug in zero we get: (2e^0-2)/0

e^0 is 1 so we have 2-2/0 or 0/0. So we have an indeterminate form type 0/0.

This means we have to apply L'Hospital's Rule.

As a reminder L'Hospitals Rule is \lim_{x\to \ c} \frac{f'(x)}{g'(x)}

Meaning that we take the derivative of the top and bottom function as the approach some value "c". We can do this with a 0/0 indeterminate form.

So:

The derivative of 2e^x - 2 is just 2e^x

and the derivative of x is 1

So we are left with \lim_{x \to \ 0} 2e^x

Plugging in zero we see this gives us 2 as 2(e^0) = 2(1) = 2.

Hence, \lim_{x \to \ 0} \frac{2e^x-2}{x} = 2
