Of the following reactions, which one produces oxygen gas?
fermentation
anaerobic respiration
aerobic respiration
photosynthesis

The correct option is: D. Photosynthesis

Explanation:

Photosynthesis is a biological process in green plants by which food such as sugar (like glucose C₆H₁₂O₆), is synthesized from water (H₂O) and carbon dioxide (CO₂) from the atmosphere, in the presence of light energy. This process produces oxygen gas (O₂) as a by-product.

This reaction converts the light energy from the sun to chemical energy.

The reaction involved is: 6 CO₂ (g) + 6 H₂O + light → C₆H₁₂O₆ (s) + 6 O₂ (g)

Photosynthesis is the only process among the given options, that produces oxygen gas.

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates

particle   p is an electron and particle q is a neutron
