1.A telescope is a tool that helps people observe distant objects. In the simplest telescope design, incoming light hits a lens

and is focused to a single point. This focused image is then magnified by a second lens so that it is roughly the same size as an observer's pupil. Which of the following wave behaviors plays the most important role in the functioning of this type of telescope?
Group of answer choices

reflection

resonance

refraction

interference

2.Pick the THREE statements that describe convex lenses.
Group of answer choices

They make the image of an object appear smaller.

Light rays spread out as they exit the lens.

They are thicker in the middle than at the ends

They make the image of an object appear larger.

They are thicker at the ends than in the middle.

Light rays converge as they exit the lens.

Hemoglobin has a much greater affinity for carbon monoxide than oxygen. which principle explains why a hyperbaric chamber (conta
babunello [35]

Hemoglobin has a much greater affinity for carbon monoxide than oxygen. In a hyperbaric chamber (containing high levels of oxygen) can treat carbon monoxide poisoning, by displacing carbon monoxide from Hemoglobin competitively.

Hemoglobin has a much greater affinity for carbon monoxide than oxygen. This is because, a coordinate bond is formed with Carbon monoxide and Haem structure of the hemoglobin.

Carbon monoxide with Hemoglobin is called as Carboxy haemoglobin.

Presence of oxygen displaces the Carbon monoxide with Hemoglobin that is formed due to poisoning.

Hyperbaric chamber is a chamber which contains pure oxygen in a chamber. The atmospheric pressure is kept about three to four times than the normal, such that the replacement of Carbon monoxide from Haem can occur as fast as possible since this reduces the half life of the Carboxy haemoglobin.

It is advisable not to treat Carbon monoxide poisoning yourself.

Hyperbaric oxygen is used to treat the following conditions as well:

  • Infections
  • Wounds
  • Air bubble is blood

Scientists can make atoms of large elements which have not been previously known. Identify an element that would have similar pr
olasank [31]

Answer:

Radon

Explanation:

One element that will have similar property as an atom with 118 protons is Radon because it will belong to the p-block and the noble gas group.

The element will follow atomic number 117 which is already in the 7th group on the periodic table.

  • Generally, on the periodic table, elements in the same group will have the same chemical property.
  • The valency of most elements determines their chemical behavior.
  • Since our mystery element is in the 8th group, noble gas group, it will mostly behave like any of the elements in the group.

0.785 moles of N2,fill a balloon at 1.5 atm and 301 K.<br> What is the volume of the balloon?
Tcecarenko [31]

Answer:

V = 12.93 L

Explanation:

Given data:

Number of moles = 0.785 mol

Pressure of balloon = 1.5 atm

Temperature = 301 K

Volume of balloon = ?

Solution:

The given problem will be solve by using general gas equation,

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

Now we will put the values.

V = nRT/P

V = 0.785 mol × 0.0821 atm.L/ mol.K × 301 K / 1.5 atm

V = 19.4 L /1.5

V = 12.93 L
