An ore is a type of rock that contains many minerals. But a mineral is just a part of the ore. So all ores are minerals but all minerals are not ores.
Quantum states of electrons are usually written in terms of four numbers: the principle quantum number (n), the angular momentum azimuthal number (L), the magnetic quantum number (ml), and the spin projection number (ms). The quantum number set (4,1,0,+1/2) and (4,1,1,+1/2) share the same principle quantum numbers and therefore both sit in the n=4 electron shell.
I believe this ensures the standards of the profession. By ensuring they are producing the best quality of work, the standards for their job remain consistent and high
Answer:
b=200
l=100
Explanation:
so since it is a square all sides would be equal
when you cut the square vertically the dimensions will change
the bredth would be same that is 200
but the length would be half that is 100
Answer:
The density of gold is 19. 38
Explanation:
Density is defined as the property that matter, whether solid, liquid or gas, has to compress in a given space. In other words, density is a quantity that allows you to measure the amount of mass in a given volume of a substance. So, the expression for the calculation of the density is the quotient between the mass of a body and the volume it occupies:
Density, according to the International System of Units, is usually expressed in kilogram per cubic meter (kg/m³) or gram per cubic centimeter (g/cm³). Although it can also be expressed in any other unit of mass by volume.
In this case:
- mass= 96.9 grams
- volume= 5 mL
Replacing:
density=19. 38
The density of gold is 19. 38 , that you could approximate the option 19. 32
