The difference between light reflection and refraction is simple. In reflection, the light ray striking the plane returns to the originating source or medium as the waves spring off the surface. in refraction, the waves go through the surface and it alters their speed and direction.
what is reflection?
Reflection is the bouncing back of light when it strikes a smooth surface. Generally occurs on shinny surfaces that only allow rebounding of light without permitting penetration through it. In this process, light bounces back and returns back in the same direction.
Refraction is the bending of light rays when it travels from one medium to another. This occurs in transparent surfaces that allow bending of the ray to a different medium.
In this process, light changes path i.e travels from one medium to another.

Refraction occurs when a wave crosses a boundary from one medium to another. A wave entering from an angle will change direction
Rarefraction refers to the "bending of wavelengths around an edge"of an object. diffraction depends on the size of the object relative to the wavelength of the waves.

Answer:
6H₂O + 6CO₂ + energy → C₆H₁₂O₆ + 6O₂
Explanation:
Photosynthesis:
It is the process in which in the presence of sun light and chlorophyll by using carbon dioxide and water plants produce the oxygen and glucose.
Carbon dioxide + water + energy → glucose + oxygen
water is supplied through the roots, carbon dioxide collected through stomata and sun light is capture by chloroplast.
Chemical equation:
6H₂O + 6CO₂ + energy → C₆H₁₂O₆ + 6O₂
it is known from balanced chemical equation that 6 moles of carbon dioxide react with the six moles of water and created one mole of glucose and six mole of oxygen.
The reaction completely follow the law of conservation of mass because there are equal number of atoms of each elements on both side of equation.
Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
For example:
In given photosynthesis reaction:
6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂
there are six carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of equation so this reaction followed the law of conservation of mass.

When a potassium atom loses an electron, it obtains a positive charge and becomes a potassium ion (K +). It goes as follows: K → K + + e - . Therefore, carries a positive charge.
What is potassium ?
The chemical element with the atomic number 19 and the letter K is potassium. Potassium is a silvery-white metal that may be easily and gently sliced with a knife. Within seconds of exposure, potassium metal quickly combines with air oxygen to produce flaky, white potassium peroxide.
Many significant chemicals are formed by potassium. The most prevalent potassium compound is potassium chloride (KCl). It is used to make other compounds, a salt alternative, and fertilizers.
Vegetables, fruit, potatoes, meat, bread, milk, and nuts all contain potassium. It aids neuronal activities and plays a significant part in the human body's fluid system. 95% of the potassium in the body is found inside cells, where it congregates as the ion K+.
Thus, When a potassium atom loses an electron, it obtains a positive charge and becomes a potassium ion (K +).

If it loses 1 electron, it will now have 1 more proton than electrons.
Thus, the charge would be 1+

Answer is: number of neutrons is different.
Isotopes are chemical elements with same atomic number, but different mass number (different number of neutrons).
For example, hydrogen (H), besides deuterium (mass number 2) and tritium (mass number 3), has isotope protium (mass number 1).
Atomic number is unique and defines an element. Isotopes of an element have same atomic number (same number of protons in nucleus).
Atomic number (Z) is total number of protons and mass number (A) is total number of protons and neutrons in a nucleus.
Isotopes are variants of an element that have the same number of protons but different numbers of neutrons in their atomic nuclei. This difference in neutron count gives each isotope a unique mass number.
1. Mass Spectrometry: Mass spectrometry is a technique commonly used to identify and measure the abundance of isotopes in a sample. It works by ionizing atoms or molecules and then separating them based on their mass-to-charge ratio.
2. Nuclear Magnetic Resonance (NMR) Spectroscopy: NMR spectroscopy is another powerful tool for distinguishing isotopes. It exploits the magnetic properties of atomic nuclei to determine their local environment within a molecule.
3. Radioactive Decay: Some isotopes are radioactive, meaning they undergo spontaneous decay over time, transforming into other elements or isotopes.
