A clasping handshake may be used as an analogy for an enzyme-catalyzed reaction because it represents the specific manner in which an enzyme ________. folds to form secondary and tertiary structures interacts with water binds substrate is denatured by low pH

Answers

Answer 1

A clasping handshake is similar to the way in which enzymes bind to substrates in enzyme-catalyzed reactions.

Enzymes are biological catalysts that speed up the rates of biological reactions by lowering the minimum energy required by reactants in order to arrive at products.

Enzymes are able to achieve this feat by substrate-enzyme binding. The substrate binds to the enzyme in its active site, becomes products, and the products are released from the active site of the enzyme. Thus, the enzyme is free for the binding of another substrate.

C. C2H4
D. C4H10
and what is the working

Answers

the answer is C ( i think )

The correct statement which has the same empirical formula as molecular formula is "CH3COOH".

What is empirical formula?

A chemical compound's empirical formula is a representation of the simplest whole number ratio between its constituent parts.

What is molecular formula?

The molecular formula is a depiction of the compound's actual whole number ratio between its constituent parts.

To put it another way, molecular formulas tell you how many atoms of each element are in a compound, whereas empirical formulas tell you the simplest or most reduced ratio of components.

Acetic acid has the molecular chemical formula CH3COOH. In the order C: H: O, the true whole number ratio is 2: 4: 2. In the order C: H: O, the smallest simple whole number ratio is 1: 2: 1. As a result, acetic acid's empirical formula is CH2O.

Hence, the correct option is A.

Answer:

Un par solitario o par de electrones no compartidos es un par de electrones de valencia que no se encuentra formando un enlace, ni compartido con otros átomos. Cuando un átomo se agrupa con otros para formar una molécula, sus electrones más externos -también conocidos como electrones de capa de valencia- dejan de pertenecer únicamente al átomo del que provienen, pasando a pertenecer a la molécula formada. Los orbitales atómicos de valencia dejan de existir como tales y pasan a formar orbitales moleculares con características diferentes a las originales. Como los pares solitarios se encuentran en la capa más externa de los átomos, cuando estos átomos forman moléculas pasan a formar parte del conjunto de electrones de valencia de la molécula. De esto se deduce que los pares solitarios son, de hecho, un subconjunto de los electrones de valencia de la molécula a la que pertenecen.

What are molecules?

A molecule is a collection of two or more atoms held together by attractive forces known as chemical bonds.

The International System of Units uses the mole as the unit of material quantity. How many elementary entities of a specific substance are present in an object or sample is determined by its quantity.

The tiniest component of any substance is capable of existing independently while maintaining its chemical and physical properties and is composed of one or more elements.

Out of these molecules, water has more molecules than  1 mole Al(OH)₃ and 1 mole NaCl. They don't have the same number of moles.

To solve for number one we must follow these steps:

m = 703.55 g − 345.8 g

m = 357.75 g

Then we solve for the density-

d = 357.75 g / 225 mL

d = 1.59 g/mL

Answer for number 5) 1.59 g/mL

Density= Mass/Volume

therefor- Mass = 65.14g and Volume = 35.4mL

Density = 65.14g/35.4 mL = 1.84 g/mL

Answer for number 6) 1.84 g/mL

Question 7-

g = (0.8765 g/mL)(250.0 mL) = 219.1 g

Answer: 219.1 g

Question 8-

Density = mass/volume

Mass = 1587g

4.5cm x 5.2cm x 6cm = 140.4 cubic-cm

Volume = 140.4 cubic-cm

Mass/volume = 1587/140.4 = 11.3 g/cm^3

Answer: 11.3 g/cm^3

Question 9:

First calculate the volume of iron

49.10mL − 45.50mL = 3.60mL

Density = mass/volume;

density = 28.5g/3.60 mL= 7.92 g/mL

Answer: 7.92 g/mL

Question 10:

Volume = 2500.0g / 10.5g/cm3 = 238.095cm^3

Now we round up the answer to 238cm^3

Answer: 238cm^3

Excess Na2SO4 (aq) is added to a 42.53 mL sample of Ba(NO3)2(aq).

1. What is the formula of the precipitate?
The formula for the precipitate is 2Na(NO3)(aq).

2. If 3.046 grams of precipitate was formed, what was the molarity of the Ba(NO3)2(aq)?

Answers

1. The formula of the precipitate formed is Ba₂SO₄(s)

2. The molarity of the Ba(NO₃)₂ solution is 0.188 M

1. Determination of the formula of the precipitate formed.

We'll begin by writing the net ionic equation for the reaction between Na₂SO₄ and Ba(NO₃)₂. This is given below:

Na₂SO₄(aq) + Ba(NO₃)₂(aq) —>

2Na⁺(aq) + SO₄²¯(aq) + Ba²⁺(aq) + 2NO₃¯(aq) —> Ba₂SO₄(s) + 2Na⁺(aq) + 2NO₃¯(aq)

Cancel the spectator ions (i.e Na⁺ and NO₃¯) to obtain the net ionic equation

SO₄²¯(aq) + Ba²⁺(aq) —> Ba₂SO₄(s)

Therefore, the formula of the precipitate formed is Ba₂SO₄(s)

2. Determination of the molarity of Ba(NO₃)₂

We'll begin by calculating the number of mole of in 3.046 g of precipitate, Ba₂SO₄

Molar mass of Ba₂SO₄ = (2×137) + 32 + (4×16) = 370 g/mol

Mass of Ba₂SO₄ = 3.046 g

Mole of Ba₂SO₄ =?

Mole = mass /molar mass

Mole of Ba₂SO₄ = 3.046 / 370

Mole of Ba₂SO₄ = 0.008 mole

Next, we shall determine the number of mole of Ba(NO₃)₂ required to produce 0.008 mole of Ba₂SO₄

Na₂SO₄(aq) + Ba(NO₃)₂(aq) —> Ba₂SO₄(s) + 2NaNO₃(aq)

From the balanced equation above,

1 mole of Ba(NO₃)₂ reacted to produce 1 mole Ba₂SO₄.

Therefore,

0.008 mole of Ba(NO₃)₂ will also react to produce 0.008 mole of Ba₂SO₄

Thus, 0.008 mole of Ba(NO₃)₂ is required for the reaction.

Finally, we shall determine the molarity of the Ba(NO₃)₂ solution

Mole of Ba(NO₃)₂ = 0.008 mole

Volume = 42.53 mL = 42.53 / 1000 = 0.04253 L

Molarity of Ba(NO₃)₂ =?

Molarity = mole / Volume

Molarity of Ba(NO₃)₂ = 0.008 / 0.04253

Molarity of Ba(NO₃)₂ = 0.188 M

Answers

That car moves or accelerates faster which has the higher speed.

If the red car accelerate at higher speed than black car then the red car reach first on the destination but if the black car moves with higher speed than red car then the black car reach its destination earlier than the red car.

The conclusion can be drawn when the image is present or any data but there is no data or image present which provides us accurate information so we can conclude logically that car which moves at higher speed will move faster than the other car.

1. Atomic Radius:

  Atomic radius increases down a group and decreases across a period. Lithium (Li) has a larger atomic radius than beryllium (Be) due to Li's additional electron shell. Be has fewer shells, resulting in a smaller radius.

2. 2nd Ionization:

  Second ionization energy is the energy needed to remove a second electron. Potassium (K) has higher second ionization energy than calcium (Ca) due to K's electron configuration ([Ar] 4s¹), requiring breaking into a filled shell.

3. C-C Bond:

  Carbon-to-carbon bond energy differs based on bond type. Ethene (C₂H₄) has a stronger double bond, requiring more energy to break, while ethane (C₂H₆) has a weaker single bond.

4. Boiling Point:

  Boiling points relate to intermolecular forces. Chlorine (Cl₂) has lower boiling point due to weaker dispersion forces compared to bromine (Br₂), with stronger dispersion forces leading to higher boiling point.
