Need help!!! Don’t understand

Answers

A) Neither carbon nor oxygen has satisfied the octet rule

To begin with...

The bond between carbon and oxygen is suppose to have 3 bonds in between

Second:

The lone pairs are not drawn. Since carbon monoxide has 3 bonds in between it should have a lone pair (2 dots) left over on each atom.

Reminder: in order to satisfy the octet rule EACH atom must have 8 electrons. Carbon has 4 valence shell electrons and oxygen has 6. In order to satisfy this rule, there should be 3 bonds in between which makes a total of 6 for each atom plus the lone pairs that make up the 8.

I hope that’s not too confusing, if you still have any questions please let me know in the comments (:

98 m/s2
0.5 m/s2
21 m/s2
2 m/s2

Answers

Answer:

The solution is

Explanation:

a = f/m

a =7/14

a=1/2

a=0.5

Acceleration of bike is 0.5 m/s²

Given that:

Force used in push = 7 N

Mass of bike = 14 kg

Find:

Acceleration of bike

Computation:

Force = Mass × Acceleration

Force used in push = Mass of bike × Acceleration of bike

7 = 14 × Acceleration of bike

Acceleration of bike = 7 / 14

Acceleration of bike = 0.5 m/s²

It takes 7.21 1019 J of energy to remove an electron from an iron atom. What is the maximum wavelength of light that can do this

Answers

Answer:

2.75 × 10^-45 m

Explanation:

From;

E= hc/wavelength

h= Plank's constant= 6.6 × 10^-34 Js

c= speed of light=3× 10^8 ms-1

Wavelength = 6.6 × 10^-34 × 3× 10^8/7.21 × 10^19

Wavelength= 2.75 × 10^-45 m

According to Le Chatelier's principle, what happens to the equilibrium constant (K) when the concentration of the reactants is doubled? The value of the equilibrium constant (K) is doubled. The value of the equilibrium constant (K) is halved. The value of the equilibrium constant (K) remains the same. The value of the equilibrium constant (K) changes unpredictably.

Answers

Answer:

The value of the equilibrium constant (K) remains the same.

Explanation:

A state of dynamic equilibrium is said to have been achieved in a reaction system when the rate of forward reaction equals the rate of reverse reaction.

At equilibrium, doubling the initial concentration of reactants have no effect on the equilibrium constant K. The equilibrium will rather shift to the left or right as required in order to annul the constraint.

A pharmacist mixed some 10%-saline solution with some 15%-saline solution obtain 100 mL of a 12%-saline solution. How much of the 10-saline solution did the pharmacist use in the mixture

Answers

Answer:

10%-saline solution = 60mL

15%-saline solution = 40mL

Explanation:

Let

10%-saline solution = x

15%-saline solution = y

x + y = 100

0.1x + 0.15y = 100*0.12

x + y = 100 (1)

0.1x + 0.15y = 12 (2)

from (1)

x = 100 - y

Substitute x = 100 - y into

0.1x + 0.15y = 12

0.1(100 - y) + 0.15y = 12

10 - 0.1y + 0.15y = 12

- 0.1y + 0.15y = 12 - 10

0.05y = 2

y = 2 / 0.05

y = 40mL

Substitute y = 40 into

x + y = 100

x + 40 = 100

x = 100 - 40

x = 60mL

10%-saline solution = 60mL

15%-saline solution = 40mL

List all the layers of the atmosphere and give one SENTENCE description or characteristic for each layers.

Answers

Answer:

Troposphere, stratosphere, mesosphere, and thermosphere.

Explanation:

Troposphere - It is the lowest region of the atmosphere, extending from the earth's surface to a height of about 3.7–6.2 miles (6–10 km), which is the lower boundary of the stratosphere.

Stratosphere - It is the layer of the earth's atmosphere above the troposphere, extending to about 32 miles (50 km) above the earth's surface (the lower boundary of the mesosphere).

Mesosphere - It is the region of the earth's atmosphere above the stratosphere and below the thermosphere, between about 30 and 50 miles (50 and 80 km) in altitude.

Thermosphere - It is the region of the atmosphere above the mesosphere and below the height at which the atmosphere ceases to have the properties of a continuous medium. The thermosphere is characterized throughout by an increase in temperature with height.

Answer:

The First layer is the troposphere. The troposphere is what we live in. It creates weather for us. Second layer is the Stratosphere. You will find the ozone layer in it. The ozone layer helps protect us from ultraviolet radiation (UV) from the sun. In fact, the ozone layer absorbs most of the UV radiation the sun sends to us. Life as we know it wouldn't be possible without this layer of protection. Third layer is Mesosphere. The Mesosphere is very important for earth's protection. The mesosphere burns up most meteors and asteroids before they are able to reach the earth's surface. Fourth layer is Thermosphere. The Thermosphere absorbs the sun radiation making it very hot.

Explanation:: I don't know if you include this one but the fifth layer is the Exosphere. Although the exosphere is the most distance layer of earth's atmosphere it is the layer that is the planet's first line of defense against the sun's rays. It is also the first layer to come into contact and protect the earth from meteors, asteroids, and cosmic rays.

Cobalt (Co) has an atomic mass of 59 and an atomic number of 27. Which statement correctly describes an atom of cobalt?

A. An atom of cobalt contains more neutrons than protons.
B. An atom of cobalt contains more electrons than protons.
C. An atom of cobalt contains the same number of neutrons and protons.
D. An atom of cobalt contains the same number of neutrons, electrons and protons.

Answers

Answer:

A

Explanation:

27 us the number of protons when we subtract 27 from 59 it will be 32 because a mass number is the sum of proton and neutron but tell u more on the comment

Answer: A - An atom of cobalt contains more neutrons than protons.

Explanation: The atomic number is the number of protons in an atom. The atomic mass is the sum of protons & neutrons in an atom. So, with simple math we can figure out the number of neutrons. Total 59 - 27 protons = 32 neutrons. Which means that A is the only right answer in this case.

Little Extra: A & B would both be correct if Cobalt was a negatively charged ion. An atom is an ion if it is charged, and an ion is either negatively charged or positively charged. For example, if Cobalt had 27 protons & 26 electrons it's overall charge would be positive since it has more protons than electrons. And it would be negatively charged if Cobalt had 27 protons & 28 electrons. No charge if there are 27 protons & 27 electrons because proton +1 and electron -1. Imagine 27-27=0 no charge, 27-26= +1 charge, 27-28= -1 charge
