Answer:
Alchemy is generally seen as an archaic proto-science based on superstition that is of little interest to the modern chemist. ... In Western alchemy, perfection is achieved through the action of the Philosophers Stone. Alchemists believed that it could turn any substance into gold, prolong life and cure illness
Explanation:
Answer:
The binding energy released is 1.992 X 10⁻¹⁸ J
Explanation:
Given;
mass of the alpha particle, m = 6.64 x 10⁻²⁷ kg
speed of the alpha particle, c = 3 x 10⁸ m/s
The binding energy released is given by;

where;
m is mass of the particle
c is speed of the particle
E = 6.64 x 10⁻²⁷ (3 x 10⁸)²
E = 1.992 X 10⁻¹⁸ J
Therefore, the binding energy released is 1.992 X 10⁻¹⁸ J
Answer:

Explanation:
The<em> mole fraction</em> of a component in a mixture is the number of moles of the component divided by the total number of moles of all the components, multiplied by 100.
The symbol X is used to represent the mole fraction.

<u />
<u>1. Convert masses in grams to number of moles</u>
Formula:
- number of moles = mass in grams / molar mass
a) Lithium bromide
- Chemical Formula: LiBr
- Molar mass: 86.845 g/mol

b) Water

c) Total number of moles = 2.00 mol + 20.0 mol = 22.0 mol
<u>2. Mole fraction of lithium bromide</u>
