Identify the types of chemical reactions occurring in the chemical equations. Tiles respiration photosynthesis combustion reaction of fossil fuels Pairs methane + oxygen → water + carbon dioxide + heat arrowBoth glucose + oxygen → carbon dioxide + water + energy arrowBoth water + carbon dioxide + sunlight → oxygen + glucose arrowBoth

Respuesta :

Photosynthesis = water + carbon dioxide + sunlight → oxygen + glucose

Respiration = glucose + oxygen → carbon dioxide + water + energy

Combustion Reaction = methane + oxygen → water + carbon dioxide + heat

The right matches are:

Photosynthesis: H2O + CO2 + sunlight ==> O2 + glucose

Plants, photoautotrophic organisms, are able to use light energy to synthesize organic molecules from mineral compounds. All of these reactions are grouped under the term photosynthesis.

Photosynthesis is carried out by autotrophic carbon organisms, thanks to particular pigments: chlorophyll.


Respiration: glucose + O2 ==> H2O + CO2 + energy

Cellular respiration allows the production of ATP through the breakdown of glucose assisted by oxygen. We talk about aerobic metabolism. This metabolism is to oppose the fermentation which is done without oxygen (anaerobic) and that we detail in another file. Cellular respiration is divided into two phases, one cytoplasmic and the other mitochondrial.


Combustion Reaction: methane + oxygen ==> water + carbon dioxide + heat.

Methane is the main constituent of city gas (or natural gas). So it's the gas that is burned when

uses the bunsen burner.

During the combustion of methane blue flame, it is called complete combustion

- the reagents are: methane and dioxygen

- the products are: water and carbon dioxide

- The balance sheet is: methane + dioxygen → water + carbon dioxide
