The answer is true, catalysts increase rates by lowering the activation energy of a reaction. Catalysts lower the reaction energy and so the reaction occurs faster. Enzymes perform the role of biological catalysts. Most metabolic pathways of the body are controlled by enzymes. Enzymes by classification are proteins. <span />
Your answer would be, Sugar is the solute, and water is the solvent. a solution is the mixture of two, or more substances.
Hope that helps!!!
<u>Answer:</u> The wavelength of the photon is 486.2 nm and it lies in the visible region
<u>Explanation:</u>
To calculate the wavelength of light, we use Rydberg's Equation:

Where,
= Wavelength of radiation
= Rydberg's Constant = 
= Higher energy level = 4
= Lower energy level = 2
Putting the values in above equation, we get:

Converting this into nanometers, we use the conversion factor:

So, 
As, the range of wavelength of visible light is 400 nm - 700 nm. So, the wavelength of the given photon lies in the visible region
Hence, the wavelength of the photon is 486.2 nm and it lies in the visible region
The formula for Hexafluoride is F6S.
Explanation:
- Combination or synthesis reaction
- Decomposition or cracking reaction
- Single replacement or single displacement
A combination or synthesis is a type of reaction that involves the formation of a single product from tow or more reactants:
K + J → KJ
The formation of a single compound form the union of their constituent element falls into this category of reaction.
The large and negative heat of formation is the driving force for this reaction.
A decomposition or cracking reaction is one in which two or more products are formed from a single reactant:
TK → T + K
The breaking down o a compound into its individual components like elements and other compounds falls into this category.
The driving force for this type of reaction is the high positive heat of formation and instability of the compound.
A single replacement or single displacement reaction is one in which a substance is replacing another.
TO + P → TP + O
The replacement of a metallic ion in solution by a metal atom higher in the activity series than the metal in a solution falls into this category of reaction.
