Explanation:

The periodic table arranges elements based on their atomic numbers in a systematic fashion.

There are about 110 elements on the periodic table with each of them having their unique atomic numbers.

On periodic table, most atoms are designated as:

ₓⁿT

T is the symbol of the atom

X is the atomic number of the atom

n is the mass number

Atomic number is the number of protons in atoms in an element. Protons are the positively charged particles.

Mass number is the number of protons and neutrons in an atom. Both protons and neutrons are in the nucleus of an atom.

Atomic number = number of protons = number of electrons

Mass number = number of protons + number of neutrons

Number of neutrons = mass number - number of protons

Number of neutrons = mass number - atomic number

How to calculate moles

blondinia [14]

Explanation:

First you must calculate the number of moles in this solution, by rearranging the equation. No. Moles (mol) = Molarity (M) x Volume (L) = 0.5 x 2. = 1 mol.

For NaCl, the molar mass is 58.44 g/mol. Now we can use the rearranged equation. Mass (g) = No. Moles (mol) x Molar Mass (g/mol) = 1 x 58.44. = 58.44 g.

Electron A falls from energy level X to energy level Y and releases blue light. Electron B falls from energy level Y to energy l

MrMuchimi

Answer: Transition from X to Y will have greater energy difference.

Explanation: For studying the energy difference, we require Planck's equation.

$E=\frac{hc}{\lambda}$

where, h = Planck's Constant

c = Speed of light

E = Energy

$\lambda$ = Wavelength of particle

From the equation, it is visible that the energy and wavelength follow inverse relation which means that with low wavelength value, energy will be the highest and vice-versa.

As electron A falls from X-energy level to Y-energy level, it releases blue light which has low wavelength value (around 470 nm) which means that it has high energy.

Similarly, Electron B releases red light when it falls from Y-energy level to Z-energy level, which has high wavelength value (around 700 nm), giving it a low energy value.

Energy Difference between X-energy level and Y-energy level will be more.

Describe how a chemical change follows the law of conservation of matter.<br> give examples pls

Paha777 [63]

Explanation:

In any chemical change, one or more initial substances change into a different substance or substances. ... According to the law of conservation of matter, matter is neither created nor destroyed, so we must have the same number and kind of atoms after the chemical change as were present before the chemical change

Example:

The carbon atom in coal becomes carbon dioxide when it is burned. The carbon atom changes from a solid structure to a gas but its mass does not change.
