Subsurface mining disturbs more land than surface mining true or false

Chemistry
1 answer:
Allisa [31]3 years ago
5 0

Answer:

False

Explanation:

Surface mining disturbs more land compared to subsurface mines.

During surface mining, huge mounds of earth is removed inorder to access mineral deposits. The deeper lying the deposit, the more the earth is removed and disturbed.

In subsurface mines, tunnels and a system of shaft are used to access the ore body. Data about the geometry and positioning of the ore helps to plan how to effectively access it.

3% Hydrogen Peroxide has an oral LD50 of 900 mg/kg. Acetic Acid has an oral LD50 of 3310 mg/kg. Which one is more hazardous to c
Maurinko [17]
LD50 is defined as the lethal dose 50% which describes the amount of material required to kill 50% of the testing population. It is given in units of mg of chemical per kg of bodyweight of the recipient. 

Comparing hydrogen peroxide and acetic acid, we see that peroxide has a lower LD50 of 900 mg/kg, with acetic acid having LD50 = 3310 mg/kg. When comparing LD50 values, the smaller value will be the more toxic compound. What this means is that in this case, a smaller amount of peroxide is required to kill 50% of the testing population compared to acetic acid.

Therefore, 3% hydrogen peroxide is more hazardous to consume.
