When a Pd-106 nuclide is struck with an alpha particle, a proton is produced along with a new nuclide. What is this new nuclide

Answers

Answer 1

When a Pd-106 nuclide is struck with an alpha particle, a proton is produced along with a new nuclide. The new nuclide is Ag-109.

What are alpha particles?

Alpha particles (a) are made up of two protons and two neutrons that are tightly bound together.

They are emitted from the nucleus of some radionuclides during alpha decay, a type of radioactive decay.

Thus, the correct option is D, Ag-109.

A sample of methane gas that has a volume of 3.8 L at 5°C is heated to 86°C at constant pressure. Calculate its new volume.​

Answers

3.8 L / 278 K = V2/ 359 K = 4.90719

New volume would be 4.9

According to  the Charle's law as pressure is constant the new volume of gas is 4.907 L.

What is Charle's law?

Charles law is an experimental gas law which provides description about the behavior of gases which tend to expand on heating.It states that, at constant pressure, the temperature is in direct proportion with the volume that is,V∝T or V₁/T₁=V₂/T₂.The relation between volume and temperature is linear as the temperature increases volume also increases.

The graph of volume versus temperature is a straight line passing through the origin.The law was proposed by Jacques Charles , a french physicist in 1780.

In the given problem , on substituting values in above formula, V₂=3.8×278/359=4.907 L.

What volume of a 2.60 M HCl solution should you use to prepare 2.80 L of a 0.200 M HCl solution

Answers

Answer:

0.215 L HCl

Explanation:

Using the relationship (M1 x V1 = M2 x V2) between Molarity (M) and Volume (v or L), we can find the volume of the 2nd volume amount.

First we rearrange our relationship equation to: [tex]V_2 = \frac{M_1 * V_1 }{M_2}[/tex]

Now, plug in the values. [tex]V_2 = \frac{0.2 * 2.8}{2.6}[/tex]

Calculating these values, we end up with the answer:

Addition reaction between water molecules and alkene molecules produces alcohol.

What is addition reaction?

Addition reaction generally takes place across the unsaturated carbon compounds.

When water molecule (H₂O) is added to the alkene which may be ethene (C₂H₄) molecule then formation of product i.e. ethanol (CH₃CH₂OH) takes place through the addition of hydrogen and hydroxyl group across the double bond. And reaction is shown in the attached image.

You need to make an aqueous solution of 0.173 M zinc fluoride for an experiment in lab, using a 500 mL volumetric flask. How much solid zinc fluoride should you add

Answers

Answer:

About 8.94.

Explanation:

Because we are given a 500. mL volumetric flask, the solution will have a volume of 500. mL.

Find the number of moles of zinc fluoride needed. Recall that molarity is simply moles per liter of solution:

[tex]\displaystyle 500.\text{ mL} \cdot \frac{0.173\text{ mol ZnF$_2$}}{1\text{ L}} \cdot \frac{1\text{ L}}{1000\text{ mL}} = 0.0865\text{ mol ZnF$_2$}[/tex]

Convert this to grams. The molecular weight of zinc fluoride is 103.38 g/mol:
[tex]\displaystyle 0.0865\text{ mol ZnF$_2$} \cdot \frac{103.38\text{ g ZnF$_2$}}{1\text{ mol ZnF$_2$}} = 8.94\text{ g ZnF$_2$}[/tex]

Answers

From the calculations in the question, we have that the dissociation constant is 2.5 * 10^-10.

What is Ka?

The term Ka has to do with the acid dissociation constant and it is obtained from; Ka = [H+] [OBr–]/[HOBr]

Now, we are told that the hydrogen ion concentration at equilibrium is 9. 1 × 10–6 and the HOBr concentration is 0.33 M, it the follows that;

(3) The pressure exerted by the CO2 gas is 28.7 atm

(4) The temperature of the Cl2 gas is -118.37⁰C

Number of moles of oxygen

The number of moles of oxygen occupied at the given condition is calculated as follows;

PV = nRT

n = PV/RT

where;

T = 25ºC = 273 + 25 = 298KR is ideal gas constant = 0.08205 L.atm/mol.K

n = (2.5 x 1.2) / (0.08205 x 298)

n = 0.123 mol

Volume of the gas

PV = nRT

V = nRT/P

where;

R = 62.36 L.mmHg/mol.K

V = (2 x 62.36 x 293) / (720)

V = 50.75 Liters

Pressure of the gas

PV = nRT

P = nRT/V

where;

n is number of moles

Molar mass of CO2 = 44

n = 25/44 = 0.568

P = (0.568 x 0.08205 x 308)/(0.5)

P = 28.7 atm

Temperature of the gas

T = PV/nR

molar mass of Cl2 = 71 g

n = 5/71 = 0.07

T = (900 x 0.75)/(0.07 x 62.36)

B: K-C is ionic, and C-O is nonpolar covalent.
C: K-C is ionic, and C-O is polar covalent.
D: K-C is polar covalent, and C-O is polar covalent.

Answers

Answer:

I'm not all the way sure but I think it is C

Explanation:

The reason is because an ionic bond essentially donates an electron to the other atom participating in the bond. Also, the C-O I think is polar since it is evenly distributed.

Based on the electronegativity difference between them, K-C is ionic, and C-O is polar covalent.

What is a bond?

A bond is formed by the interaction of two atoms. A bond can be either ionic or covalent.

Now we have to look at the electronegatives on each bond. The electronegativity difference between the K-C bond is larger than that between the C-O bond hence, K-C is ionic, and C-O is polar covalent.

Why are intermolecular forces generally much weaker than bonding forces?.

Answers

Explanation:

Intermolecular forces: These are the attractive or repulsive forces acting between two molecule in interaction.

The attractive forces between molecules are of several types based on the interaction between molecules also known as Vander wall forces.

Bonding forces: They are also attractive forces acting between two constituents (atom, ion, radicals etc) and stabilizes the constituent particles by loss of energy. The bond between any two species are formed by the overlapping of corresponding orbitals.

Whenever positive overlapping occurs between species, the formation of Bonding molecular orbital (BMO) takes place. and when electron enters into BMO it loses energy. Alternative form of explaining the concept is Individual electron possess more energy than the electrons that paired or Bonded.

Now coming to your question,

All the intermolecular forces are formed by weak attractive forces (vanderwall forces) which includes Ion-dipole forces, Ion-induced-dipole forces, Dipole-dipole forces, Dipole-induced-dipole forces, Hydrogen bonds & London forces.

All these forces are temporary and weak, and formed by the poles generated on molecule due to shift of electron, for e.g. Any molecule having more electron at one pole and less electron at another pole then that molecule start acting as charged body when that charged body comes in contact with opposite pole of another charged body the interaction takes place, since the electrons are dynamic and unsteady it's not possible that the pole will keep acting same as before. hence the intermolecular forces are generally weaker.

On the other side the Bonding electrons, are formed by the various strong overlapping such as between Head to Head overlapping leads to formation of Sigma bond which is the strongest bond takes alot of Energy to break & Lateral overlapping lead to formation of pi bond which is also stronger bond than that of Hydrogen bond.
