Answer:
diamonds are carbon based and have a giant covalent structure
Explanation:
This is what gives diamonds its strength and rigidity.
Diamonds are different from graphite due to the way the atoms are arranged
Explanation:
Population is hugely dependent on the environment and it's factors. The physical, chemical and biological components of the environment plays vital roles in the sustenance of all life on earth.
A change in the environment can lead to terrifying consequences. Let's examine some of the changes:
- Climate change can lead to flooding of biological habitats and where people typically reside. This can lead to death and loss of life.
- Drought can lead to decline in food production. During a drought, a place receives little to no rainfall and the land is not fit for agricultural practices. This will eventually lead to famine.
- Pollution: it is the introduction of harmful substances into the environment. Pollution is harmful to the population.
- Geological hazards; earthquakes, volcanic eruptions,mass wasting and so on can lead to a crash in population.
- Wildfires, tornadoes, dust bowls e.t.c are changes in the environment that can cause severe consequences on the population.

Answer:
n = 2.1 mol
Explanation:
Given data:
Number of moles of gas = ?
Volume of gas = 56.3 L
Pressure of gas = 0.899 atm
Temperature of gas = 20°C (20+273 = 293 k)
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
0.899 atm × 56.3 L = n × 0.0821 atm.L/ mol.K × 293 k
50.614 atm.L = n × 24.055 atm.L/ mol
n = 50.614 atm.L / 24.055 atm.L/ mol
n = 2.1 mol
