Answer:
150 g of potassium contained 3.8 moles of potassium.
Explanation:
Given data:
Mass of potassium = 150 g
Moles of potassium = ?
Solution:
Number of moles = mass/ molar mass
Molar mass of potassium = 39 g/mol
Now we will put the values in formula:
Number of moles = mass/ molar mass
Number of moles = 150 g/ 39 g/mol
Number of moles = 3.8 mol
150 g of potassium contained 3.8 moles of potassium.
It means the process carried by the cell is spontaneous.

Explanation:
Nuclear reactors are the heart of a nuclear power plant. They contain and control nuclear chain reactions that produce heat through a physical process called fission. That heat is used to make steam that spins a turbine to create electricity. Nuclear power plants use heat produced during nuclear fission to heat water. The heat produced during nuclear fission in the reactor core is used to boil water into steam, which turns the blades of a steam turbine. As the turbine blades turn, they drive generators that make electricity
