Only 0.7% of natural uranium is 'fissile', or capable of undergoing fission, the process by which energy is produced in a nuclear reactor. The form, or isotope, of uranium which is fissile is the uranium-235 (U-235) isotope. ... Most is then converted into uranium hexafluoride, ready for the enrichment plant.
That they are different.. because they have the same mass but different densities
Answer:
a salad with lettuce, cheese, seeds, tomatoes, broccoli, and other vegetables is an example of a heterogeneous mixture .
The concentration of the bromine solution, given the data is 0.04 M
<h3>What is molarity? </h3>
Molarity is defined as the mole of solute per unit litre of solution. Mathematically, it can be expressed as:
Molarity = mole / Volume
<h3>How to determine the mole of bromine molecule (B₂)</h3>
- Mass of B₂ = 1.6 g
- Molar mass of bromine molecule (B₂) = 80 × 2 = 160 g/mol
- Mole of bromine molecule (B₂) = ?
Mole = mass / molar mass
Mole of bromine molecule (B₂) = 1.6 / 160
Mole of bromine molecule (B₂) = 0.01 mole
<h3>How to determine the molarity of the bromine solution</h3>
- Mole of bromine molecule (B₂) = 0.01 mole
- Volume of solution = 250 cm³ = 250 / 1000 = 0.25 L
- Molarity bromine solution =?
Molarity = mole / Volume
Molarity bromine solution = 0.01 / 0.25
Molarity bromine solution = 0.04 M
Thus, molarity of the bromine solution is 0.04 M
