What is the name of N2CI4? Explain how you determined the bond type and the steps you used to determine the naming convention for the compound.

Answers

Answer 1

The name of N2CI4 is Dinitrogen tetrachloride.

I determined the bond type because there was no metal in the formula, and I determined the name by taking the prefixes of the subscripts and adding them to the elements. Since both nitrogen and chlorine want to gain electrons. we can obey the octet rule with a compromise of neither losing nor gaining electrons.

Two atoms share electrons to achieve the octet rule and form a covalent bond. Accordingly, the indicated compounds are covalent compounds. Explain what is most likely to happen when an atom of this element approaches an atom with seven valence electrons. Move to the outermost shell. Because both fluorine and hydrogen can only form ionic bonds.

How would you calculate the percent relative abundance of cu-63 with the mass 62.9296 g and cu-65 with the mass 64.9278 g, when the average mass of cu is 63.546?

Answers

The percent relative abundance of Cu-63 is 69.15% and Cu-65 is 30.85%.

The atomic mass is the average mass of an element.

m(Cu) = 63.546 g; the average mass of copper

m(⁶³Cu) = 62.9296 g; average mass of copper-63 (Cu-63) isotope

m(⁶⁵Cu) = 64.9278 g; average mass of copper-65 (Cu-65) isotope

ω(⁶³Cu) = ?; average abundance of isotopes Cu-63

ω(⁶⁵Cu) = 1 - ω(⁶³Cu);  average abundance of isotopes Cu-65

Ar(Cu) = ω(⁶³Cu) × m(⁶³Cu) + ω(⁶⁵Cu) × m(⁶⁵Cu)

63.546 g = ω(⁶³Cu) × 62.9296 g + (1 - ω(⁶³Cu)) × 64.9278 g

63.546 = 62.9296 × ω(⁶³Cu) + 64.9278 - 64.9278 × ω(⁶³Cu)

1.9982ω(⁶³Cu) = 1.3818

ω(⁶³Cu) = 1.4738 ÷ 1.9982

ω(⁶³Cu) = 0.6915 × 100%

ω(⁶³Cu) = 69.15%

ω(⁶⁵Cu) = 100% - 69.15%

ω(⁶⁵Cu) = 30.85%

2) Atom is the smallest unit of any matter.

3) Atoms can neither be created nor be destroyed.

4) Atoms of different elements combine with each other in fixed number or ratios to give new molecules.

A piece of titanium metal with a mass of 15.7 g is heated in boiling water to 99.5oc (initial temperature of metal) and then dropped into a coffee cup calorimeter containing 75.0g of water at 21.7oc with a specific heat of 4.184 j/goc. when thermal equilibrium is reached, the final temperature is 24.3oc. calculate the specific heat of titanium.

Answers

The specific heat of titanium is 0.69 J/ g c.

The specific heat of titanium can be calculated by using the principle of calorimetry.

According to this principle, the heat lost by one body is equal to the heat gained by another body in contact with it.

The heat(Q) is calculated by the following formula,

Q = m(s)(ΔT)

Here m is the mass of the body

s is the specific heat of the body

ΔT is the change in temperature

Thus, the heat lost by titanium metal is equal to the heat gained by water present in the calorimeter,

(msΔT)Titanium= (msΔT)Water

Putting the given values in the above equation

15.7 x s x 99.5-24.3 = 75 x 4.184 x 24.3-21.7

s = 0.69 J/g C

What is density?

The density of a substance is the ratio of the mass of the substance and its volume.

Density = mass/volume.

For the first problem: mass = 57.3 g, volume = 4.7 cm3

Density of the metal = 57.3/4.7

                                   = 12.19 g/cm3

The density of gold is 19.3 g/cm3. Thus, the bar of metal is not pure gold.

For the second problem: density = 1.19 x [tex]10^{-3[/tex] g/ml, mass = 50.0 g

Volume = mass/density

                 = 50/1.19 x [tex]10^{-3[/tex]

Answer: Though a hydrogen atom has only one electron, it contains a large number of shells, so when this single electron jumps from one shell to another, a photon is emitted, and the energy difference of the shells causes different wavelengths to be released... hence, mono-electronic hydrogen has many spectral lines.

Explanation: sry its late

Answer: Your welcome!

Explanation:

The frequency of a line in the hydrogen spectrum is determined by the difference in energy between two energy levels in the hydrogen atom. The energy levels are determined by the electron's angular momentum and can be expressed as the quantum number n. The energy of the lines is then determined by the difference between two energy levels (n1 and n2) and is given by the equation ΔE = hc/λ = (R/n2^2) - (R/n1^2), where R is the Rydberg constant and h is Planck's constant. The frequency of the line is then determined by the equation ν = ΔE/h.

Answers

Find hydrogen ion concentration of the original solution using the law of mass conservation after some further algebraic manipulation:

[H+]2+Ka[H+]-KaCa=0 (Ka - weak acid dissociation constant, Ca – weak acid concentration)

Ka=10-6.3=5.01*10-7

Set up the quadratic equation: [H+]2+5.01*10-7*[H+]-5.01*10-7 *0,10=0

Solve the quadratic equation: [H+]=2*10-4

pH=3.7

What is law of mass conservation?

The law of conservation of mass, also known as the principle of mass conservation, in physics and chemistry states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time because the mass of the system cannot change and therefore quantity cannot be added to or subtracted.

Therefore,

for a particular redox reaction, clo−2 is oxidized to clo−4 and fe3+ is reduced to fe2+ . complete and balance the equation for this reaction in basic solution. the phases are optional.

Answers

For a particular redox reaction ClO2– is oxidized to ClO4– and Fe3 is reduced to Fe2 .

What is redox reaction?

Redox is a sort of chemical reaction where the substrate's oxidation states change.

An rise in an object's oxidation state or the loss of electrons is referred to as oxidation.

Gaining electrons or lowering an atom's oxidation state are both considered to be reductions in the context of chemical reactions.

Redox reactions can be divided into two categories:

only one electron (typically) moves from the reducing agent to the oxidant during an electron transfer. Redox couples and electrode potentials are frequently used to describe this type of redox reaction.

Atomic transfer refers to the movement of an atom from one substrate to another. For instance, when iron rusts, iron atoms get more oxidized as they change into an oxide at the same time.

Is using a fuel cell to separate water into hydrogen and oxygen a physical or chemical separation?

Answers

using a fuel cell to separate water into hydrogen and oxygen is chemical separation.

fuel cell uses concept of called reversible electrolysis for seperation.The process of separating water into hydrogen and oxygen is known as electrolysis. An electrolyte separates the anode from the cathode in a fuel cell. Different types of electrolyte and the ionic species they conduct play a major role in how different fuel cells operate.At the anode, water reacts to produce positively charged hydrogen ions and oxygen (protons).The hydrogen ions move arbitrarily across the to the cathode as the electrons go through an external circuit.Hydrogen gas is created at the cathode when hydrogen ions and electrons from the external circuit combine.In order to reach the Hydrogen Energy Earthshot objective of lowering the price of clean hydrogen by 80% to $1 per kilogramme in ten years, electrolysis is a primary method of hydrogen production.
