Explanation:
One positive impact of the mining is that the sale of the Bauxite will increase their economic power by bringing in foreign exchange into their economy. This will improve services such as healthcare and infrastructure.
A negative impact is the destruction of the nature preserve and disturbing the ecosystem could lead to a devastating loss in biodiversity. A decrease in biodiversity will increase crop pests and diseases that destroy standing crops, and an increase in the prevalence of diseases in the community.
Answer:
1.6605 × 10⁻²³ g / atom , 9.99 amu
Explanation:
Atoms present in 1 mole = 6.022 × 10²³ atoms
Given that
Moles of common Eastern mole = 8.3 moles
So,
Atoms in 8.3 moles are:
8.3 moles = 6.022 × 10²³ × 8.3 atoms
Also,
Average mass = Mass of the sample / Number of atoms
Mass of sample = 83 g
Average mass = 83 g / 6.022 × 10²³ × 8.3 atoms = 1.6605 × 10⁻²³ g / atom
In amu :
1 amu = 1.66 × 10⁻²⁴ g / atom
So,
Average mass = 1.6605 × 10⁻²³ / 1.66 × 10⁻²⁴ amu = 9.99 amu
Answer:
Hydrogen bonds
Explanation:
Hydrogen bonds are bonds formed in polar molecules in which an hydrogen atom is directly joined to a highly electronegative atom such as oxygen or nitrogen or fluorine.
A hydrogen bond is just an electrostatic attraction between a hydrogen atom of one molecule and the electronegative atom of a neighboring molecule.
Methanol has a formula of CH₃OH and the hydrogen bond is between the H and O.
`2H + 02 -----> 2H2O is a Balanced chemical equation.
