Please explain the difference between reactants and products in a chemical reaction.
KonstantinChe [14]

Answer

A reactant is a substance that is present at the start of a chemical reaction. These are what breakdown to form products and its always to the right.

A product is a substance that is present at the end of a chemical reaction. These are what are formed after the reactants are broken down, the end result.

The reactions of the Calvin cycle are not directly dependent on light, but they usually do not occur at night. Why? Group of ans
kati45 [8]

Answer:

The correct answer is a The calvin cycle requires products only produced when the photsystems are illuminated .It is often too cold at night for the reaction to take place.

Explanation:

It is true that the reactions of calvin cycle are not directly depends on light but depends on the products such as ATP and NADPH produced during light reaction.

       ATP and NADPH is formed by the illumination of photosystems by sun light.So during night time there is no chance for the light dependent illumination of the photosystems.

    As a result the ATP and NADPH are not formed during night .That"s why reactions of calvin cycle does not occur at night.

The electronegativity of the element affects all of the following except a- type of bond it forms with other elements b- the boi
seraphim [82]

The electronegativity of the element affects the ability of its compounds to dissolve in different solvents.

<h3>What is the meaning of electronegativity?</h3>

Electronegativity is a measure of an atom's ability to attract shared electrons to itself.

Polar bonds have a positive and negative side to them, and therefore can attract water dipoles and dissolve in water.

If the polarities of the solvent and solute match (both are polar or both are nonpolar), then the solute will probably dissolve.

If the polarities of the solvent and solute are different (one is polar, one is nonpolar), the solute probably won't dissolve.

Hence, option D is correct.

When molecules have the same number of each element but those atoms are arranged differently they are known as____________.
Karo-lina-s [1.5K]

Answer: Structural Isomers

Explanation:

The compounds having similar molecular formula but different arrangement of atoms or groups in space are called isomers and the phenomenon is called as isomerism.  

Isomers are of two types: structural isomers and stereo isomers.

Structural isomers are isomers in which molecules with the same molecular formula have different bonding patterns.

Stereoisomers are isomers in which molecules have the same molecular formula and sequence of bonded atoms but differ in the three-dimensional orientations of their atoms in space.

Thus when molecules have the same number of each element but those atoms are arranged differently they are known as Structural isomers.
