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.

The molar heat of fusion of gold is 12.550 kJ mol–1. At its melting point, how much mass of melted gold must solidify to release
KATRIN_1 [288]

The mass of melted gold to release the energy would be  3, 688. 8 Kg

<h3>How to determine the mass</h3>

The formula for quantity of energy is given thus;

Q = n × HF

Where n represents number of moles

HF  represents  heat of fusion

To find the number of moles, we have

235.0 = n × 12.550

number of moles = \frac{235}{12. 550} = 18. 725 moles

Note that molar mass of Gold is 197g/ mol

Let's note that;

Number of moles = mass/ molar mass

Mass = number of moles × molar mass

Mass = 18. 725 × 197

Mass = 3, 688. 8 Kg

Thus, the mass of melted gold to release the energy would be  3, 688. 8 Kg

50 Points: What is the mass of 6.12 moles of arsenic (As)?
ozzi

The mass of 6.12 moles of arsenic (As) is calculated to be approximately 459g.

HOW TO CALCULATE MASS:

The mass of a substance can be calculated by multiplying the number of moles of a substance by its molar mass. That is;

Mass of Arsenic = no. of moles of As × molar mass of As.

According to this question, 6.12 moles of arsenic was given and its molar mass is 74.92g/mol.

Mass of As = 6.12 mol × 74.92g/mol

Mass of As = 459g

Therefore, the mass of 6.12 moles of arsenic (As) is calculated to be approximately 459g.

True or false? The molar mass of a gas determines the amount of kinetic energy of the gas.
HACTEHA [7]
The answer is false..............<span>kinetic theory of gases is a topic that can explain many everyday observations. Have you ever wondered why water boils faster at higher altitudes? Or why inflatable pool toys seem flat after sitting in a cold garage? How about why you can smell a candle all throughout the house? All of these phenomena and many more can be explained by the kinetic theory of gases.</span>
