When discussing the Arrhenius equation and chemical / enzyme kinetics, which of the following statements is incorrect ? A. A cat

alyst lowers the activation energy of a reaction B. A high activation energy signifies that the rate constant depends strongly on temperature C. A negative activation energy indicates that the rate increases as the temperature is raised D. The activation energy, the parameter Ea in the Arrhenius equation, is the minimum energy that a molecular encounter needs in order to result in a reaction E. If a reaction has zero activation energy, its rate is independent of temperature

Answer:Name and Title:

Colleen DeBruin, Hillary Mulkavits, 11/18/2020, compounds lab.

Objectives(s):

to build chemical compounds from known elements

Hypothesis:

if I use oxygen hydrogen and carbon then I can make five new compounds in four minutes

Procedure:

The materials and procedures are listed in your virtual lab. You do not need to repeat them here. However, you should note if you experienced any errors or other factors that might affect your outcome. Using your summary questions at the end of your virtual lab activity, please clearly define the dependent and independent variables of the experiment.

Data:

Record the composition of each of your compounds below. Be sure to include the number of atoms for each element. An example has been supplied for you.

Compound Name Chemical Formula Sodium (Na) Atoms Calcium (Ca) Atoms Hydrogen (H) Atoms Oxygen (O) Atoms Carbon (C) Atoms Chlorine (Cl) Atoms

Ex: Sodium

hypochlorite NaClO 1 0 0 1 0 1

Water H20 o 0 1 2 0 0

Glucose C6H12O6 0 0 12 6 6 0

Formic/methanoic acid HCOOH 0 0 2 2 1 0

Butanoic Acid C3H7COOH 0 0 8 2 4 0

Carbon Dioxide C02 0 0 0 2 1 0

Carbon Monoxide CO 0 0 0 1 1 0

Fructose C6H12O6 0 0 12 6 6 0

0 0 0

0 0 0

0 0 0

Conclusion:

Your conclusion will include a summary of the lab results and an interpretation of the results. Please answer all questions in complete sentences using your own words.

I found as many combinations of carbon hydrogen and oxygen as possible

If there is a job that combines elements you would be doing that every day making it an every day matter

elements are like people, they are all different causing them to react differently and be more reactive

H20 has four because there are 2 oxygen and one hydrogen because of the numbers in the name of the compound

Yes because two elements can form two different types of bonds causing different outcomes

What is nacl monosaccharide disaccharide organic or inorganic?
bonufazy [111]
<span>inorganic Let's look at the choices and see why they work, or don't work. monosaccharide * Otherwise known as a simple sugar. And NaCl is definitely not a sugar of any type. So this is wrong. disaccharide * Complex sugar. And NaCl doesn't qualify either. organic * A definition of an organic compound is one that has carbon in it. NaCl has sodium and chlorine. No carbon at all, so this isn't the right answer. And I wish that organic was an earlier choice, since the sugars mentioned above are organic compounds. inorganic * This is the only possible choice. Salt is not an organic compound since it doesn't have carbon. So it can't be a sugar either. But it can and is inorganic.</span>

A Diels–Alder reaction calls for the use of 5.8 mL of a 4.0 M solution of cyclopentadiene in methanol. Calculate the number of m
Shalnov [3]

The number of mole of cyclopentadiene present in the solution is 0.0232 mole.

We'll begin by converting 5.8 mL to litre (L). This can be obtained as follow:

1000 mL = 1 L

Therefore,

5.8 mL = 5.8 / 1000

<h3>5.8 mL = 0.0058 L</h3>

Finally, we shall determine the number of mole of cyclopentadiene present in the solution. This can be obtained as follow:

Volume = 0.0058 L

Molarity = 4 M

<h3>Number of mole =?</h3>

Mole = Molarity x Volume

Mole = 4 × 0.0058

<h3>Mole = 0.0232 mole</h3>

Therefore, the number of mole of cyclopentadiene present in the solution is 0.0232 mole.
