Answer:
The answer to your question is Volume = 11.4 L
Explanation:
Data
Volume 1 = V1 = 6 L
Pressure 1 = P1 = 1 atm
Temperature 1 = T1 = 22°C
Volume 2 = V2 = ?
Pressure 2 = 0.45 atm
Temperature 2 = -21°C
Process
1.- Convert temperature (°C) to °K
T1 = 273 + 22 = 295°K
T2 = 273 + (-21) = 252°K
2.- Use the combined gas law to solve this problem
P1V1 / T1 = P2V2 / T2
-Solve for V2
V2 = P1V1T2 / T1P2
-Substitution
V2 = (6)(1)(252) / (295)(0.45)
- Simplification
V2 = 1512 / 132.75
- Result
V2 = 11.38 L
Answer:
0.0685 mL
Explanation:
To find the volume of the sample, divide the mass by the density.
(1.00 g)/(14.6 g/mL) = 0.0685 mL
It's classified as an acid
Some of the negative consequences of cobalt mining are pollution and child trafficking.
<h3>Effects of cobalt mining</h3>
Many young children are made to work in mines generally either due to continued struggle for survival or forced into it by child traffickers.
Apart from that, cobalt mining causes pollution in the environment. Inhalation of dust containing cobalt causes a host of health issues such as lung cancer and damage to human skin.
Other effects include soil degradation and pollution, water pollution due to mine run-offs, etc.
