I think alcohol is not a depressant because if you use alcohol with other medications it produces bad side affects which is harmful so try alcohol
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.

Answer:
0.95 kPa
Explanation:

(4.0)(1.9) = (
)(8.0)
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.
Answer:
Explanation:

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