Calculate the energy of a photon of light with a frequency of 6.17 x 1014 Hz.

Answers

Answer:

The answer is

[tex] \huge 4.088 \times {10}^{ - 19} \:J[/tex]

Explanation:

The energy of a photon of light can be found by using the formula

E = hf

where

E is the energy

f is the frequency

h is the Planck's constant which is

6.626 × 10-³⁴ Js

From the question

f = 6.17 × 10¹⁴ Hz

We have

E = 6.17 × 10¹⁴ × 6.626 × 10-³⁴

We have the final answer as

[tex]4.088 \times {10}^{ - 19} \: \: J[/tex]

ch question carries 2 mark. Time Remaining : 00 : 46 : 33 Some oxides are given below. (i)Na2O (ii)NO2 (iii) CO2 (iv) MgO a) Which are the basic oxides among these? b) What is the name of the aqueous solution of CO2 ?

Answers

Further explanation

The basic oxide is an oxide-forming a base solution.

These oxides are mainly from group 1 alkaline and group 2-alkaline earth

If this oxide is dissolved in water it will form an alkaline solution

LO + H₂O --> L(OH)₂ ---> alkaline earth

L₂O + H₂O --> LOH --> alkaline

So the basic oxides  : Na₂O and MgO

Na₂O + H₂O --> NaOH (sodium hydroxide, strong base)

MgO + H₂O --> Mg(OH)₂ (magnesium hydroxide, strong base)

The aqueous solution of CO₂ , obtained by dissolving CO₂ in water

CO₂ + H₂O --> H₂CO₃ (carbonic acid)

In general, basic oxide is obtained from metal oxide, while acid oxide is obtained from non-metal oxide

What is the chemical formula?

A chemical formula of a compound provides the chemical proportions of each element in a given compound or molecule. The chemical formula of a compound can be written with help of chemical symbols of elements, numbers, and symbols, such as plus (+) and minus (−) signs, dashes, commas, and brackets.

A chemical formula exhibits of no words related to the compound but can be drawn in some simple chemical structures. Chemical formulae of the compound should be limited in power than chemical names as well as chemical structural formulae.

There are two kinds of chemical formulas in chemistry: empirical formula and molecular formula.

The chemical formula gives in the formation of the different types of elements in the compound and the ratio of their atoms.

Consider the reactions C2H4(g) + 2O2(g) → 2CO(g) + 2H2O(g) ∆H = −758 kJ mol−1 2C(s) + 2H2(g) → C2H4(g) ∆H = +52 kJ mol−1 H2(g) + O2(g) → H2O(g) ∆H = −242 kJ mol−1 The enthalpy of formation of carbon monoxide is A −111 kJ mol−1 B −163 kJ mol−1 C −222 kJ mol−1 D -464 kJ mol−1

Answers

C2H4(g) + 2O2(g) → 2CO(g) + 2H2O(g)       ∆H1 = −758 kJ mol−1       ....1)

2C(s) + 2H2(g) → C2H4(g)                           ∆H2 = +52 kJ mol−1        ....2)

H2(g) + O2(g) → H2O(g)                               ∆H3 = −242 kJ mol−1     ....3)

Now, enthalpy of formation of carbon monoxide is given by :

∆H = ∆H1 + ∆H2 - ∆H3

∆H = ( -758 + 52 - ( -242 ) ) kJ mol−1  

∆H = −464 kJ mol−1

Therefore, the enthalpy of formation of carbon monoxide is -464 kJ mol−1.

Hence, this is the required solution.

An orbital that could never exist according to the quantum description of the atom is

Answers

Answer:

d. 3f

Explanation:

An orbital in chemistry is defined as the wave function that defines the position of electrons in an atom.

There are four types of orbitals that include s, p, d, and f. On the basis of the quantum description, 3f orbital does not exist because in the third energy level only three sublevels are present that are s, p, and d that can hold a  maximum of 18 electrons.

Hence, the correct answer is "d.3f".

For the 3 principal orbitals, f suborbital has not been possible. Thus the orbital that could never exist according to the quantum description of the atom is 3f. Thus the correct option is d.

Quantum mechanics helps in the determination of the electron address. The electron address has been given by the 4 quantum numbers namely,

Principal quantum numberAzimuthal quantum numberMagnetic quantum numberSpin quantum number

The principal quantum number gives the information to the orbital, and the azimuthal quantum number gives the information of the subshell.

The orbitals have been formed by the mixing of the bonding and anti-bonding orbital. The mixing of the 3 orbital has resulted in the 3 suborbital namely s, p, and d.

Thus for the 3 principal orbitals, f suborbital has not been possible. Thus the orbital that could never exist according to the quantum description of the atom is 3f. Thus the correct option is d.

Jason is designing a computer model that shows the structure of different molecules. His model uses spheres to represent the atoms and lines to represent bonds. His program calculates the correct angle of the bonds and allows the user to rotate the molecule to see it in three dimensions. Which change could Jason make to his program to make the model more like a real molecule?

Answers

Answer:

Explanation:

The computer model that is being described seems pretty accurate, the only change I would consider making would be a zoom in/out feature that allows the user to zoom-in in order to see the protons and electrons that make up the atoms which ultimately make up the molecule. Mainly since they are also a very important part of the molecules' structure and final composition and can be a vital piece of data, especially being able to visualize it.
