<span>A Homogeneous Catalyst exists in the same physical state as that of the reaction it catalyzes.

Explanation:
Catalysts are classifies as follow,
1. Homogeneous Catalyst
2. Heterogeneous Catalyst

</span>Homogeneous Catalyst are those which are in same phase as that of reactants are.

Example:

Acetic Acid + Ethanol + H₂SO₄ → Ethyl Acetate + H₂O + H₂SO₄

In this reaction catalyst and reactants all are in same phase i.e. Liquids.

Heterogeneous Catalyst are those which are in different phase as that of reactants are.

Example:

Ethene + H₂ + Ni → Ethane + Ni

In this reaction ethene and hydrogen are gases while Nickle catalyst is in solid state.

Hello! I just need a little bit of help. I'm supposed to design an experiment on how reaction rates are determined and affected

Get 3 cups of water at the exact same temperature, using the thermometer to check.
Label the cups as ‘whole’, ‘pieces’, and ‘crushed’
Next, get something to dissolve, in this case, polident. Take one of the polident tablets and break it into 4 pieces, and set it aside.
Take another polident tablet and this time put it into a different cup, and crush it. Set it aside.
Keep the last tablet whole.
Set up your stopwatch and drop the polident tablet that is whole in the cup labeled ‘whole’, starting the stopwatch at the same time.
Watch the cup and see when the tablet is fully dissolved, then stop the stopwatch.
Record the time in the table.
Repeat steps 6-8 for both the ‘pieces’ and ‘crushed’ tablets.

Hope this helps! Please let me know if you need more help, or if you think my answer is incorrect. Brainliest would be MUCH appreciated. Have a great day!

Stay Brainy!

The chemical formula C₂H₆O, which is designated as option D, is equivalent to this structural formula.

<h3><u>What is a Chemical Formula ?</u></h3>

Chemical element symbols, numbers, and occasionally additional symbols like parentheses, dashes, brackets, commas, and plus (+) and minus () signs are used in a chemical formula to represent information about the chemical proportions of the atoms that make up a certain chemical compound or molecule.

An empirical formula represents by symbols, such as Na for sodium and Cl for chlorine, with subscripts that show the relative number of atoms in each.
The composition of any member of an entire class of compounds can be represented by a general formula, a sort of empirical formula.
