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.

As we know that Molarity is given as,
M = moles / V
Solving for V,
V = moles / M ------------------(1)
Also, moles is equal to,
moles = mass / M. mass -------------(2)
puting value of moles from eq. 2 into eq. 1,
V = (mass / M.mass) / M
Putting values,
V = (45 g / 164 g/mol) / 1.3 mol/dm³
V = 0.21 dm³
Covalent compounds are held together with an intra molecular attraction which is weaker than metallic bond
hence covalent compounds exist as liquids, gases and soft solids
Answer:
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar
Explanation:
Answer:
A. 5.5 × 10⁻¹⁰ M, acidic
Explanation:
Step 1: Given data
Concentration of H₃O⁺: 1.8 10⁻⁵ M
Step 2: Calculate the concentration of OH⁻
We will use the ionic product of water.
Kw = 1.0 × 10⁻¹⁴ = [H₃O⁺] × [OH⁻]
[OH⁻] = 1.0 × 10⁻¹⁴/[H₃O⁺] = 1.0 × 10⁻¹⁴/1.8 10⁻⁵ = 5.5 × 10⁻¹⁰ M
Step 3: Determine if the solution is acidic, basic or neutral
- If [H₃O⁺] > 10⁻⁷ M, the solution is acidic.
- If [H₃O⁺] = 10⁻⁷ M, the solution is neutral.
- If [H₃O⁺] < 10⁻⁷ M, the solution is basic.
Then, the solution is acidic.
