Answers

Answer:

The atoms in the solid would be vibrating in position.

Explanation:

i took the test

Three grams of the same substance in different phases are stored in three different containers. Each container is barely large enough to hold the substance. Therefore, the correct option is option B.

What is atom?

Atom, the smallest unit of matter that may be separated without releasing electrically charged particles. It is also the tiniest unit of matter with the characteristics of a chemical substance. As a result, the atomic is the fundamental building component of chemistry.

The majority of the molecule is empty space. The rest of the structure is made up of a positive-charged nucleus of neutrons and protons surrounding by a swarm of negative-charged electrons. In comparison to electrons, the lightest charge particles in nature, nuclear nucleus is small yet dense. The atoms in the liquid would be vibrating in position.

Therefore, the correct option is option B.

Answers

Answer:

A new substance forms.

Explanation:

Answer:

B

Explanation:

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

A. because they have delocalized electrons
B. because they have localized electrons
C. because they have ionic bonds
D. because they have rigid bonds

Answers

Answer:

A

Explanation:

because they have delocalized electrons

Metals are malleable because they have delocalized electrons which are capable of forming ionic bonds.

What is an ionic bond?

Ionic bond or electrovalent bond is a type of bond which is formed between two elements when there is an exchange of electrons which takes place between  the atoms resulting in the formation of ions.

When the atom looses an electron it develops a positive charge and forms an ion called the cation while the other atom gains the electron and develops a negative charge  and forms an ion called the anion.

As the two atoms are oppositely charged they attract each other which results in the formation of a bond called the ionic bond.Compounds having ionic bonds are malleable and have high melting points.They are also brittle in nature.

Your advisor has given you a tube of GMP that has been sitting in the freezer for many years and wants to know the concentration. There is one problem: the spectrophotometer in the lab has been 'optimized' for use with proteins and only measures at 280 nm. You decide to give it a try. After getting and absorbance reading of 0.2, what is the concentration of GMP in the tube (assuming a 1 cm path length).

Answers

Answer:

2.22 × 10^-5M

Explanation:

From Beer-Lambert's law;

A=εcl

Where A = absorbance of GMP= 0.2

ε= molar extinction coefficient of GMP = 9000 M-1cm-1

c= concentration of GMP= the unknown

l= path length = 1 cm

c= A/εl = 0.2/ 9000 M-1cm-1 × 1 cm

c= 2.22 × 10^-5M

2.3 grams of sodium reacts with water and 0.080 grams of hydrogen has been collected what are the theoretical and percent yields of hydrogen gas?

Answers

Answer:

Theoretical yield = 0.1 g

Percent yield = 80%

Explanation:

Given data:

Mass of sodium = 2.3 g

Actual yield of hydrogen = 0.080 g

Theoretical yield = ?

Percent yield = ?

Solution:

Chemical equation:

2Na + 2H₂O    →  H₂ + 2NaOH

Number of moles of sodium:

Number of moles = mass/ molar mass

Number of moles = 2.3 g/ 23 g/mol

Number of moles = 0.1 mol

Now we will compare the moles of sodium with hydrogen to calculate the theoretical yield.

                       Na               :              H₂

                        2                :               1

                     0.1                 :             1/2×0.1 = 0.05 mol

Mass of hydrogen produced:

Mass = number of moles × molar mass

Mass = 0.05 mol × 2 g/mol

Mass = 0.1 g

Percent yield of hydrogen:

Percent yield = actual yield / theoretical yield ×100

Percent yield = 0.08 g/ 0.1 g×100

Percent yield = 0.8×100

Percent yield = 80%

within a balloon there are 3 types of gases. the first gas, A, is 6.0 grams in amount, the second gas, B, is 4.0 grams and the last, C, is 3.5 grams. The molar mass of gas "A" is 13.56 g/mol, "B" is 11.76 g/mol and "C" is 12.07 g/mol. If the total pressure inside the balloon is 15 atm, what is the partial pressure of each gas?

Answers

Answer:

Partial pressure of Gas A = 3.91 atm

Partial pressure of Gas B = 5.10 atm

Partial pressure of Gas C = 5.99 atm

Explanation:

Number of moles of gas A;

n_A = 13.56 g/mol ÷ 6 g = 2.25 moles

Number of moles of gas B;

n_B = 11.76 g/mol ÷ 4 g

n_B = 2.94 moles

Number of moles of gas C;

n_C = 12.07 g/mole ÷ 3.5 moles

n_C = 3.45 moles

Total number of moles = n_A + n_B + n_C = 2.25 + 2.94 + 3.45 = 8.64 moles

Mole fraction of gas A; X_a = 2.25/8.64

Mole fraction of gas B;X_b = 2.94/8.64

Mole fraction of gas C;X_c = 3.45/8.64

Now, partial pressure of each gas will be;

Mole fraction × Total pressure

We are given total pressure of 15 atm.

Thus;

P_a = (2.25/8.64) × 15

P_a = 3.91 atm

P_b = (2.94/8.64) × 15

P_b = 5.10 atm

P_c = (3.45/8.64) × 15

P_c = 5.99 atm

Thus;

Partial pressure of Gas A = 3.91 atm

Partial pressure of Gas B = 5.10 atm

Partial pressure of Gas C = 5.99 atm
