No amino acid molecule by itself can speed up or catalyze reactions between other molecules; however, when amino acids are joine

d together to make a protein with catalytic properties, the new structure (enzymatic protein) can speed up the rate of a specific chemical reaction. What does this illustrate?

Answer:

That the enzyme is a protein

Explanation:

Remember the proteins are groups of thousands of amino acids, by their owns, since they are very small units, they can not act as a catalyst.

But as a polymer, the protein enzyme, have different shape, size and physical and chemical properties than a single monomer.

Remember also the proteins to be active, they need certain number of amino acids join together to form a specific shape that is going to match with another molecule to speed the chemical reaction and act as an enzyme.

Answer:

Emergent properties

Explanation:

Emergent properties are those properties that appear as a result of the combination of smaller parts which themselves do not individually exhibit any of such properties.

Emergent properties are properties of a group of items, whether insects, atoms or buildings, that you would not find in any of the individual items.

The amino acids are individual molecules, when they combine to give enzymes, they display properties that individual amino acids do not exhibit separately. This a typical example if emergent properties.

How to solve this: a small dog has consumed a dangerous amount of apap. the vet has ordered: rx acetylcysteine 150mg/kg/stat. yo
Fantom [35]
Given:
Stock dose/concentration of 20% Acetylcysteine (200 mg/mL)
150 mg/kg dose of Acetylcysteine
Weight of the dog is 13.2 lb

First we must convert 13.2 lb to kg:
13.2 lb/(2.2kg/lb) = 6 kg

Then we must calculate the dose:
(150 mg/kg)(6kg) = 900 mg

Lastly, we must calculate the dose in liquid form to be administered:
(900 mg)/(200 mg/mL) = 4.5 mL

Therefore, 4.5 mL of 20% Acetylcysteine should be given.

A 30ml sample of a liquid has a mass of 50 grams. What is the density of the liquid?
mash [69]

Answer:

<h2>Density = 1.67 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

Density =  \frac{mass}{volume}

From the question

mass = 50 g

volume = 30 mL

Substitute the values into the above formula and solve for the density

That's

Density =  \frac{50}{30}  \\  =  \frac{5}{3}  \\  = 1.66666...

Wr have the final answer as

<h3>Density = 1.67 g/mL</h3>

Hope this helps you

"determine the mass of oxygen" in a 7.9 g sample of al2(so4)3.
jeyben [28]

Answer:

              4.43 g of Oxygen

Explanation:

As shown in Chemical Formula, one mole of Aluminium Sulfate [Al₂(SO₄)₃] contains;

                          2 Moles of Aluminium

                          3 Moles of Sulfur

                          12 Moles of Oxygen

Also, the Molar Mass of Aluminium Sulfate is 342.15 g/mol. It means,

          342.15 g ( 1 mole) of Al₂(SO₄)₃ contains  =  192 g (12 mole) of O

So,

                         7.9 g of Al₂(SO₄)₃ will contain  =  X g of O

Solving for X,

                       X  =  (7.9 g × 192 g) ÷ 342.15 g

                      X =  4.43 g of Oxygen
