Write the general formula of an alkane and use this to predict the 97th member
of the alkane series.

Answers

Answer 1

Explanation:

The general formula of an alkane is given as;

        CₙH₂ₙ₊₂

n is the number of the member;

 For the 97th member in the series;

 n  = 97;

 2n + 2  = 2(97) + 2  = 196

So, the 97th member is;

                C₉₇H₁₉₆

This is how to apply the formula of alkanes which are saturated hydrocarbons to find any member of the series.

The compound whose molecules have the highest average kinetic energy is?

Answers

Answer:

C)

Explanation:

The warmer the molecules, the higher the average kinetic energy.

"As stated in the kinetic-molecular theory, the temperature of a substance is related to the average kinetic energy of the particles of that substance. When a substance is heated, some of the absorbed energy is stored within the particles, while some of the energy increases the motion of the particles. This is registered as an increase in the temperature of the substance." -lumen learning

Lithium has two isotopes, lithium-6 weighing 6.015 amu (7.5% abundance), and lithium-7
weighing 7.016 amu (92.5% abundance). What is the atomic mass of lithium?
with calculations

Answers

Answer:

The answer is 6.941 but I dont really have the explanation

Explanation:

The atomic mass of lithium will be 6.9458 amu.

What is Atomic Mass ?

The mass of an atom of a chemical element expressed in atomic mass units.

It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.

Calculation :

Consider 10000 atoms of Li ;

742 of them would have mass 6.02.9258 of them would have mass 7.02

.

Hence,

The total mass of these 10000 Li atoms would be ;

(742 × 6.02) + (9258 × 7.02) = 69458

∴ 1 Li atom on average would have mass =  69458 / 10000 = 6.9458 amu

Therefore, The atomic mass of lithium will be 6.9458 amu.

Emma draws a sketch of what happens to light as it moves through air and then into a tank of water. describe what happens to the speed of light as it enter the water.
Answer if you know, if you don't move on please! If you don't know comment not answer. Thank you!!

Answers

Answer:

The speed of light becomes slower in denser medium which is water in this case.

Explanation:

We know the lens law of Refraction which states

[tex]\frac{Sin(i)}{Sin(r)} =[/tex]  Refractive index of second medium /Refractive index of the first     medium

= Velocity of light in medium 1 (V1)/ velocity of light in medium 2 (V2)

When light rays fall from air medium into water which is a denser medium bending of light or change in the direction of light occurs which is knows as Refraction.

When refraction occurs speed of the light rays are also varied as we can see it from the Lenz's Law. suppose two light rays parallel to each other falling on the air-water interface at an angle , the first ray will reach the interface and bend about the normal and then the second ray. We also observe when light enters denser medium the speed of light becomes slower, also the bending of light when going from rarer to denser it bends towards normal of the surface and when it move from denser to rarer medium it moves away from the normal to the surface.

221 A grocery shop has different types of fruit: one box contains 10 mangos, another
contains 7 avocados and the third box contains 5 lemons.
The same shop has 20% organic food. 50% inorganic food, and 30% of the things they sell
are juices.
3 marks)
A) Represent the types of fruit in bar graph.
B) Represent the sales in pie graph.

Answers

Answer:

A) Please see the required bar graph attached

B) Please see the required pie graph attached

Explanation:

The given data are;

The number of each fruit in each box are;

First box contains 10 mangoes

Second box contains 7 avocados

Third box contains 5 lemons

The percentage of the things they sell are;

Organic food = 20%

Inorganic food = 50%

Juices = 30%

A) The bar graph is plotted with Microsoft Excel

The height of each column is equivalent to the number of fruit in the box

Each column represents a box of fruit

B) The pie graph (chart) is generated with Microsoft Excel

The steps to draw the pie chare are;

1) Draw a circle

2) Partition the circle into segments proportional to each percentage from the center of the circle as follows;

The sum of angles at the center of the circle = 360°

The angle of the segment that will represent the 20% organic food in the pie chart = 20/100 × 360° = 72°

Therefore, the segment representing organic food will have an angle of 72° at the center of the circle

Similarly, the segment representing inorganic food will have an angle of  50/100 × 360° = 180° at the center of the circle

The segment representing juices will have an angle of  30/100 × 360° = 108° at the center of the circle.

Answer:

Ionic compounds are compounds made up of ions. These ions are atoms that gain or lose electrons, giving them a net positive or negative charge. Metals tend to lose electrons, so they become cations and have a net positive charge. Ions of opposite charge are held together by very strong ionic bonds within the compound.

from the equation we see the relationship between the moles of co2 and O2 and we find that they have the same number of moles
So we need .005mole of O2

How can electronegativity be used to explain the reaction we see in terms of the numbers and types of bonded being formed in lithium?

Answers

Explanation:

Lithium is an electropositive element that readily loses electrons.

Oxygen is electronegative and it will readily accept electrons.

 Due to this significant electronegativity differences between the two species they form electrovalent or ionic bonds between them.

  2atoms of Li lose two electrons:

      Li  →  Li²⁺ + e⁻

             Lithium isoelectronic with helium

 For oxygen;

      O + 2e⁻   →  O²⁻

                          Oxygen is isoelectronic with Neon

Two ions of the lithium combines with the oxygen to form the bond;

                   4Li + O₂  →  2Li₂O

The electrostatic attraction between the two ions forms the ionic bond
