you have a 5.0 ml sample of a protein in 0.5m nacl. you place the protein/salt sample inside dialysis

Answers

The final Concentration of salt having a 5.0 ml sample of a protein in 0.5m nacl. you place the protein/salt sample inside dialysis is 0.62mM.

What is Concentration?

Concentration is defined as the ratio of number of moles of substance to the volume of the substance occupied.

The dialysis is normally dilution of the solution as the dialysis bag the salt present in protein sample is pass and go to the dialysing rhe solvent (water).

Calculation

As we know that,

M1V1 = M2V2

M1 and M2 are the initial and final concentration of NaCl in the dialysis bag.

V1 and V2 are the initial and final volume of NaCl in the dialysis bag.

Given,

M1 = 0.5M

V1 = 5mL = 0.005L

V2 = 4 + 0.005 = 4.005L

By substituting all the values, we get

M2 = 0.5 × 0.005/4.005

= 0.00062M

= 0.62mM.

Thus, we calculated that the final Concentration of salt is 0.62mM.

what do you think will happen to the temperature if you use 75 ml of hcl and 75 ml of naoh instead of the 50 ml each that you used in experiment 1?

Answers

The thing that will happen to the temperature if you use 75 ml of HCl and 75 ml of NaOH instead is that it increases as more heat is released.

How to explain the reaction?

A neutralization occurs when NaOH and HCl are combined. Each chemical reaction has a unique heat of reaction, which is the heat exchanged during the process.

The reaction in issue is exothermic (emits heat), and the amount of heat emitted relies on the chemicals used, their concentrations, and the working temperature (it is produced at a low temperature).

The fluctuation in temperature and the mass used determine how much heat is allocated.

In this case, the thing that will happen to the temperature if you use 75 ml of HCl and 75 ml of NaOH instead is that it increases as more heat is released.

When iron is placed in nitrogen no occurs

Answers

Nothing happens if the iron rod is inserted into the nitrogen. However, when the iron rod is suspended in the air.

A non-metal, nitrogen is. As a result, it typically interacts with metals to create ionic compounds. Only when the reactants produce products that allow the system as a whole to release energy does the reaction take place. If the system requires energy to undergo the reaction, the reaction cannot take place. When iron is exposed to oxygen and moisture for an extended length of time, a process known as iron oxide occurs. At the atomic level, oxygen bonds to iron to produce the complex known as an oxide, which weakens the metal bond.

Answers

A covalent bond is likely to be polar when one of the atoms sharing electrons is more electronegative than the other atom.

When the electronegativity difference is greater, the bond polarity is increasing.

Electronegativity (χ) is a property that describes the tendency of an atom to attract a shared pair of electrons.

Atoms with higher electronegativity attracts more electrons towards it, electrons are closer to that atom.

For example, water (H₂O) is a polar molecule. Atom of oxygen has higher electronegativity and negative charge, while atom of hydrogen has lower electronegativity and positive charge. Atoms of hydrogen and oxygen are connected by polar covalent bonds.

Taking into account the definition of atomic number and mass number, the three true statements are:

If Zinc has an atomic number of 30 and a mass number of 65, the correct number of protons, neutrons, and electrons, respectively, is: 30,35,30If Lithium has an atomic number of 3 and a mass number of 7, the correct number of protons, neutrons, and electrons, respectively, is: 3,4,3If Calcium has an atomic number of 20 and a mass number of 40, the correct number of protons, neutrons, and electrons, respectively, is: 20,20,20

Subatomic particles

All atoms are made up of subatomic particles: protons and neutrons, which are part of their nucleus, and electrons, which revolve around them. Protons are positively charged, neutrons are neutrally charged, and electrons are negatively charged (electrons).

Atomic number

The atomic number of a chemical element is the total number of protons that each atom of that element has.

Atoms in nature are electrically neutral, so the number of positive and negative particles is the same. That is, in an atom that has no charge, the atomic number also indicates the number of electrons.

Mass number

The mass number indicates the total number of particles in the nucleus. That is, the mass number is the sum of the number of protons and the number of neutrons in the atomic nucleus:

Mass number = (number of protons) + (number of neutrons)

So, If you know the number of protons and the mass number, the number of neutrons can be calculated as:

Number of neutrons= mass number - number of protons

This case

Considering the definition of atomic and mass number, you can know:

Zinc has an atomic number of 30 and a mass number of 65. The correct number of protons and electrons is 30, while the number of neutrons is 65-30= 35Magnesium has an atomic number of 12 and a mass number of 24. The correct number of protons and electrons is 12, while the number of neutrons is 24 -12= 12Lithium has an atomic number of 3 and a mass number of 7. The correct number of protons and electrons is 3, while the number of neutrons is 7-3= 4Calcium has an atomic number of 20 and a mass number of 40. The correct number of protons and electrons is 20, while the number of neutrons is 40 -20= 20Fluorine has an atomic number of 9 and a mass number of 19. The correct number of protons and electrons is 9, while the number of neutrons is 19 -9= 10

Finally, the three true statements are:

If Zinc has an atomic number of 30 and a mass number of 65, the correct number of protons, neutrons, and electrons, respectively, is: 30,35,30If Lithium has an atomic number of 3 and a mass number of 7, the correct number of protons, neutrons, and electrons, respectively, is: 3,4,3If Calcium has an atomic number of 20 and a mass number of 40, the correct number of protons, neutrons, and electrons, respectively, is: 20,20,20

a 3.214 g sample of magnesium reacts with 8.416 g of bromine (br2). the only product is magnesium bromide (mgbr2). how much mgbr2 is formed?

Answers

The reaction between 3.214 g magnesium and 8.416 g bromine produces  9.7 g of MgBr2.

The balanced chemical reaction of magnesium and bromine is shown below.

Mg + Br2 → MgBr2

Step 1: Convert the given mass of reactants to moles of reactants

moles Mg = mass Mg / molar mass Mg

moles Mg = 3.214 g / 24.31 g/mol

moles Mg = 0.1322 mol

moles Br2 = mass Br2 / molar mass Br2

moles Br2 = 8.416 g / 159.808 g/mol

moles Br2 = 0.0527 mol

Step 2: Bromine (Br2) is determined to be the limiting reactant. Since the stoichiometric ratio between the reactants is equal to 1, the reactant with a lower number of moles would be the limiting reactant.

Step 3: Convert moles of Br2 to the mass of MgBr2. Their stoichiometric ratio is also 1, which makes the solution easier.

mol Br2 = mol MgBr2

mass MgBr2 = mol MgBr2 * molar mass MgBr2

mass MgBr2 = 0.0527 mol * 184.118 g /mol

mass MgBr2 = 9.70 g

Answers

The ideal gas equation can be used to determine the molar mass of the substance with the help of the moles. The molar mass of the gas having a mass of 0.458 grams is 9.15g/mol.

What is the ideal gas law?

Ideal gas law gave the relation between the moles, pressure, temperature, volume, and the gas constant. The moles of the ideal hypothetical gas can be used to calculate the molar mass.

An ideal gas equation is given as:

PV =nRT

Given,

Mass = 0.458 gm

Pressure (P) = 0.98 atm

Volume (V) = 1.2 L

Temperature (T) = 287 K

Gas constant (R) = 0.0821

Substituting values in ideal gas as:

0.98 × 1.2 = n × 0.0821 × 287

n = 1.18 ÷ 23.56

n = 0.05moles

Now, moles are used to calculate molar mass as:

molar mass = mass ÷ moles

= 0.458 ÷ 0.05
