Answers

Answer:

a)2

b)12.5

c)1.5

Explanation:

a)

pH = -log [H^+]

pH = -log [0.01]

pH = 2

b)

pOH = -log[OH^-]

pOH = -log [0.035]

pOH= 1.5

But

pH + pOH = 14

pH = 14 - pOH

pH= 14 - 1.5

pH = 12.5

c)

pH = -log[H^+]

pH= -log[0.030]

pH = 1.5

1 and 4 options are correct

An enzyme can catalyze a reaction with either of two substrates, S1 or S2. The Km for S1 was found to be 2.0 mM, and the Km, for S2 was found to be 20 mM. A student determined that the Vmax was the same for the two substrates. Unfortunately, he lost the page of his notebook and needed to know the value of Vmax. He carried out two reactions: one with 0.1 mM S1, the other with 0.1 mM S2. Unfortunately, he forgot to label which reaction tube contained which substrate. Determine the value of Vmax from the results he obtained:
Tube number: 1
Rate of formation of product:0.5
Tube number: 2
Rate of formation of product: 4.8

Answers

Answer:

100.5 ≈ 101

Explanation:

Km for S1 = 2.0 mM

Km for S2 = 20 mM

Given that : S1 = S2 =  hence Vmax for either S1 or S2 can represent

The Vmax can be calculated using the data Given and equation below

Vo = Vmax [s] / ( Km + [s] )  ------ (1)

Vo = 0.5

[s] = 0.1 mM

km = 20 mM

making Vmax subject of  equation 1

Vmax = 0.5 ( 20.1 mM) / (0.1 mM )

         = 100.5 ≈ 101

What are elements in the tall columns of the periodic table called?
A. Representative elements
B. Valence elements
C. Atomic elements
D. Period elements

Answers

The elements in the tall columns of the periodic table are called representative elements or main group elements. They exhibit similar chemical properties within their respective groups due to their shared number of valence electrons. The terms "valence elements," "atomic elements," and "period elements" are not commonly used or recognized in the context of the periodic table.

The correct answer is option  A.

The elements in the tall columns of the periodic table are called "A. Representative elements," also known as the "main group elements" or "group A elements." These elements are found in groups 1, 2, and 13 to 18 (excluding the transition metals) on the periodic table.

Representative elements are characterized by having similar chemical properties within their respective groups. This similarity arises from the fact that elements within the same group have the same number of valence electrons, which are the electrons in the outermost energy level of an atom. Valence electrons play a crucial role in determining the chemical behavior and reactivity of an element.

The representative elements include the alkali metals (Group 1), alkaline earth metals (Group 2), boron group (Group 13), carbon group (Group 14), nitrogen group (Group 15), oxygen group (Group 16), halogens (Group 17), and noble gases (Group 18). These elements exhibit a wide range of properties, from highly reactive metals to nonmetals and inert gases.

The term "valence elements" mentioned in option B is not commonly used in the context of the periodic table. Valence electrons are indeed significant in determining chemical properties, but they are not specific to the elements in the tall columns. Valence electrons are found in elements across the periodic table.

"Atomic elements" mentioned in option C is a vague term and does not specifically refer to the elements in the tall columns. All elements on the periodic table are atomic in nature, as they are composed of atoms.

"Period elements" mentioned in option D is not a recognized term in the context of the periodic table.

In conclusion, the elements in the tall columns of the periodic table are known as representative elements or main group elements. These elements exhibit similar chemical properties within their respective groups due to their shared number of valence electrons.

Therefore, from the options provided the correct one is A.

what is the relationship between netforce and acceleration based on the situation?​

Answers

Answer:

The net force is greater at the second situation as well as the acceleration due to the contribution of the second guy.

Explanation:

Hello.

In this case, since the net force is computed via adding all the exerted forces on a body, for the first situation we can see that the net force equals the force provided by that guy when pulling, whereas in the second situation the net force equals the force of both of the guys pulling the car:

[tex]F_N_1=F_1\\\\F_N_2=F_1+F_2[/tex]

For the acceleration, we can see that applying an extra force (due to the second guy) turns out into a greater acceleration, that is why the car at the second situation reaches the tree whereas the other one does not.

Which statement(s) are true for both fusion and fission reactions? (1 point)
a. Only 1
b. Only 2
c. Both 1 and 2
d. Neither 1 nor 2

Answers

Answer:

Neither

Explanation:

The statements are true for both fusion and fission reactions are the fission is the breaking of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei join together releasing large amounts of energy. Therefore, option D is correct.

What do you mean by fission ?

The term fission is defined as when a neutron slam into a larger atom, forcing it to excite and split into two smaller atoms.

Additional neutrons are released, which can set off a chain reaction. A tremendous amount of energy is released when each atom splits.

When a neutron strikes an atom of uranium-235, it splits into two lighter nuclei, krypton and barium.

Both fission and fusion reactions involve the conversion of some mass into energy in order to form a new nucleus or nuclei, which requires some nuclear binding energy.

Thus, option D is correct.

Answer: 1.9 x 10^4

Explanation:

A dog has a mass of 19 kg. The mass of the dog in grams, expressed in scientific notation, is 1.95 × 10⁴ g.

What is mass?

Mass is the quantity of matter in a physical body. The product of the compound's molar mass and the substance's moles are defined as mass.

Measuring units to determine the size, weight, or quantity of any object. Seven fundamental measurement units are utilized in daily life and across the globe.

These units of measurement are the meter, which is used to measure distance, and the second, which is used to measure. Grams and kilograms are the measuring units that are used to measure the quantity of a solid item.

The mass of the dog in grams is:

1 kilogram = 1000 grams

19.5 kg × (10³ g/1 kg) = 1.95 × 10⁴ g.

Thus, the mass of the dog in grams is 1.95 × 10⁴ g.

75 g of a metal is heated to a temperature of 99C. The metal is then placed in a calorimeter containing 145 g of water at a temperature of 25C. The temperature of the water in the calorimeter increase to a final temperature of 28C. What is the specific heat of the metal?

Answers

Answer:

0.34 J / g ⁰C

Explanation:

Let the specific heat of metal be s .

heat will be lost by hot metal and gained by water .

heat lost by metal = mass x specific heat x loss of temperature

= 75 x s x ( 99 - 28 ) = 5325 s

heat gained by water = mass x specific heat x gain of temperature

= 145 x 4.18 x ( 28 - 25 ) = 1818.3

heat lost = heat gained

5325 s = 1818.3

s = 0.34 J / g ⁰C

Potassium acid phthalate will serve as our primary standard. This is a large molecule (KHC8H4O4) with a molar mass of 204.2 g/mol. Instead of writing the whole formula, we abbreviate it as KHP, where "P" stands for the phthalate ion, C8H4O42-, not for phosphorus. KHP is an acidic substance, with the ionizing hydrogen being set forward in the formula for emphasis. Therefore, KHP is monoprotic and will react with NaOH in a simple 1 to 1 relationship according to the following equation:

[tex]P_1[/tex] = Initial pressure = [tex]14.8\ \text{atm}[/tex]

[tex]P_2[/tex] = Final pressure = [tex]12.3\ \text{atm}[/tex]

[tex]V_1[/tex] = Initial volume = [tex]23.5\ \text{mL}[/tex]

[tex]V_2[/tex] = Final volume

[tex]T_1[/tex] = Initial temperature = [tex]315\ \text{K}[/tex]

[tex]T_2[/tex] = Final temperature = [tex]415\ \text{K}[/tex]

From ideal gas law we have

[tex]PV=nRT[/tex]

[tex]\Rightarrow PV\propto \dfrac{1}{T}[/tex]

So

[tex]\dfrac{P_1V_1}{T_1}=\dfrac{P_2V_2}{T_2}\\\Rightarrow V_2=\dfrac{P_1V_1T_2}{T_1P_2}\\\Rightarrow V_2=\dfrac{14.8\times 23.5\times 415}{315\times 12.3}\\\Rightarrow V_2=37.25\ \text{mL}[/tex]

The final volume is [tex]37.25\ \text{mL}[/tex]

what always forms between two large air masses of different moisture and air temperature?

Answers

Answer:

"What always forms between two large air masses of different moisture and air temperature?"

Explanation:

When a cold air mass replaces a warm air mass the boundary between the two air masses is called a cold front. ... Fronts form at the boundary between air masses of different temperatures and moisture. Warm air always slopes upward over colder air.

The boundary between two air masses of different density such when it can not move called “stationary” “warm” when warmer air replaces cooler air.

What is density ?

The density  can be defined as  the mass per unit volume which means that it is the ratio between mass and volume, that means the object has  the  stuff  in a unit volume.

Density is determined by the matter where it shows how the matter is tightly crammed together and  it was put forwarded  by the Greek scientist Archimedes

To calculate the density of an object, the mass (m) can be divided by the volume (v)

Density = Mass/Volume

The different units include  SI unit of density which is kilogram per cubic meter (kg/m3) or in cgs unit of grams per cubic centimeter (g/cm3).
