4 Identify What are the starting materials
Natalka [10]

Answer:

Detail is given below.

Explanation:

Photosynthesis:

Reactants =   Carbon dioxide + water + energy

Products =    glucose + oxygen

Chemical equation:

6H₂O + 6CO₂ + energy  →   C₆H₁₂O₆ + 6O₂

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.

water is supplied through the roots, carbon dioxide collected through stomata and sun light is capture  by chloroplast.

Cellular respiration:

Reactants =  Glucose + oxygen

Products =  carbon dioxide + water + 38ATP

Chemical equation:

Glucose + oxygen → carbon dioxide + water + 38ATP

It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.

Where does oxidation and reduction take place in the reaction of Br2 + 2I- → 2Br + I2
Shkiper50 [21]
Okay, let's look at the oxidation number of each substance.
-Br2 has an oxidation number of 0 because it is in a stable form.
- I- has a -1 charge and thus has an oxidation number of -1.
- 2Br- has a -1 charge also
- I2 has an oxidation number of 0 as well.

Bromine goes from 0 to -1 and Iodine goes from -1 to 0.
Therefore, Bromine is having an electron added whilst Iodine is having an electron removed.

Oxidation is Loss of electrons so Iodine is being oxidised, Reduction is Gain of electrons so Bromine is being reduced.

Select all that apply to organic compounds. Organic compounds are only found in living things. Organic compounds can be synthesi
Andreyy89

Answer:

Correct options:

Organic compounds can be synthesized in a laboratory setting.

There are hundreds of thousands of organic compounds.

Explanation:

1) Organic compounds are only found in living things: False

Organic compounds are mainly carbon based. Although organic compounds are derived from living things like plants and animals, non-living things like sedimentary rocks are also rich in carbon.

2) Organic compounds can be synthesized in a laboratory setting: True

There are four major categories of organic compounds: carbohydrates, proteins, lipids and nucleic acids all of which can be synthesized in a laboratory.

3) Organic compounds contain carbon: False

Organic compounds are identified by the presence of both carbon and hydrogen (and sometimes other elements like O, N, S).

4)CO2 is an organic compound: False

There are no H atoms, hence CO2 is not organic.

5) There are hundreds of thousands of organic compounds: True
