What is altered by a catalyst?
JulsSmile [24]

Answer:Effect of Catalysts on the Activation Energy. Catalysts provide a new reaction pathway in which a lower Activation energy is offered. A catalyst increases the rate of a reaction by lowering the activation energy so that more reactant molecules collide with enough energy to surmount the smaller energy barrier.

Which of the following statements is true about gas particles?
satela [25.4K]

Answer:

There is a lot of empty space between them

Explanation:

We know that gas molecules are loosely packed,

Therefore there is a lot of intermolecular space...(Which basically means that there is a lot of space between the molecules or particles in a gas)

Last week you reacted magnesium with a hydrochloric acid aqueous solution and hydrogen gas was produced. Let's say that you coll
miv72 [106K]

Answer:

69.8 kilo Pasacl is the pressure of the hydrogen gas.

Explanation:

Mg+2HCl\rightarrow MgCl_2+H_2

Pressure at which hydrogen gas collected = p = 101.2 kilo Pascals

Vapor pressure water = p^o = 31.4 kilo Pascals

The pressure of hydrogen gas = P

The pressure at which gas was collected was sum of vapor pressure of water and hydrogen gas.

p=P+p^o

P =p-p^o=101.2 kPa-31.4 kPa=69.8 kPa

69.8 kilo Pasacl is the pressure of the hydrogen gas.

The enzyme, phosphoglucomutase, catalyzes the interconversion
Fittoniya [83]

Answer:

K_{eq = 19

ΔG° of the reaction forming glucose 6-phosphate =  -7295.06 J

ΔG° of the reaction  under cellular conditions = 10817.46 J

Explanation:

Glucose 1-phosphate     ⇄     Glucose 6-phosphate

Given that: at equilibrium, 95% glucose 6-phospate is  present, that implies that we 5% for glucose 1-phosphate

So, the equilibrium constant K_{eq can be calculated as:

K_{eq = \frac{[glucose-6-phosphate]}{[glucose-1-[phosphate]}

K_{eq= \frac{0.95}{0.05}

K_{eq = 19

The formula for calculating ΔG° is shown below as:

ΔG° = - RTinK

ΔG° = - (8.314 Jmol⁻¹ k⁻¹ × 298 k ×  1n(19))

ΔG° = 7295.05957 J

ΔG°≅ - 7295.06 J

b)

Given that; the concentration  for  glucose 1-phosphate = 1.090 x 10⁻² M

the concentration of glucose 6-phosphate is 1.395 x 10⁻⁴ M

Equilibrium constant  K_{eq can be calculated as:

K_{eq = \frac{[glucose-6-phosphate]}{[glucose-1-[phosphate]}

K_{eq}= \frac{1.395*10^{-4}}{1.090*10^{-2}}

K_{eq} = 0.01279816514  M

K_{eq} = 0.0127 M

ΔG° = - RTinK

ΔG° = -(8.314*298*In(0.0127)

ΔG° = 10817.45913 J

ΔG° = 10817.46 J

Match the words to the definitions below.
puteri [66]

Answer:

Explanation:

1. Turns litmus paper blue, taste bitter, donate OH- ions, feel slippery, 8-14 on pH scale.

BASE

BASE: A base is a substance that reacts with water to yield excess hydroxide ions.

Some of its characteristics are:

>It has a bitter taste

>Their aqeuos solutions have a soapy feel

>They have a PH greater than 7

>They turn red litmus paper blue

>They are electrolytes

2. The amount of ions per an amount of solvent. Ex: 10g salt/100g water

CONCENTRATION

Concentration is the amount of solute that can be found in a solution.

3. A lab procedure to deliver a measured volume of solution, generally measured in ml.

TITRATION

Titration is a laboratory procedure that is used to determine the amount of solution that is needed to drive a reaction to completion. It involves adding a solution to a known volume of another solution.

4. A substance or solution that resists changes in pH by stabilizing hydrogen ion concentration.

BUFFER

A buffer is solution that is made up of weak acids and their salts or weak bases and their salts. Such solutions are able to resist changes in PH

5. Turns litmus paper red, taste sour, donate H+, corrode metals, 0-6 on pH scale.

ACID

An acid is a proton donor, hydrogen ions.

Characteristics:

>Acids turns blue litmus paper red, they have sour taste and easily corrodes metals.

>They have a PH value between 0-6 on the scale.

>They are generally electrolytes

6. Logarithmic scale to indicate the amount of hydrogen ions in solution.

PH SCALE

A PH scale is a logarithmic scale that runs from 1-14 and is used to indicate the amount of hydrogen ions in a solution.

7. A chemical (dye created from lichens) that changes color in response to changes in pH.

LITMUS PAPER

Litmus paper is made of dyes created from lichen and it changes its color as PH changes. Acids turns blue litmus paper red while bases changes the color of litmus to blue from red. Litmus test is a popular test for solutions.

8. Acids and bases are added proportionally and result in a chemical reaction that causes the pH of a solution to reach pH 7.

NEUTRALIZATION

Neutralization is the reaction of acids and bases to produce salts and water. The endpoint of neutralization reaction signifies the point at which equal number of bases neutralizes an acid. The PH is 7 at this point.
