Answer:
This is a reflector telescope and in which it captures different wavelengths of light and it hits one mirror, bounces back and hits another and then is shown through the eyepiece. It captures all of the visible spectrum and some areas above and below it. These telescopes are better for seeing big picture and not the fine details in planets surfaces.

Part 1: Which substance has a higher solubility?
Part 2: Explain your answer for Part 1
Answers
Answer:
Answer temperatures gram is correct because there is more of a mass of numbers and the numbers are higher. (don't really know this subject, just guessing, hope this helped.)
The substance A has higher solubility then substance B because the higher the temperature the easier the substance will dissolve.
What is solubility?The word solubility is defined as the ability of a substance, the solute, to form a solution with another substance, the solvent.
It can also be defined as a property that allow sugar molecule to dissolve.
It can be defined as at a given temperature, the amount of solute that can dissolve in a given amount of solvent.
In this reaction, increasing the pressure and temperature results in increased solubility. An increase in pressure causes more gas particles to enter the liquid, lowering the partial pressure.
For exothermic reaction the temperature increases with decrease in solubility and for endothermic reaction the temperature decreases with increase in solubility.
Thus, the substance A has higher solubility then substance B because the higher the temperature the easier the substance will dissolve.

Circle the compound that has the higher boiling point and explain why we see the
differences we do
Answers
Answer:
1. Ethane has a higher boiling point
2. Heptyne has a higher boiling point
3. Octane has a higher boiling point
Explanation:
1. Ethane has stronger intermolecular attractions (van der Waal's forces) than ethene and so has the higher boiling point.
2. The longer (and the straighter) the chain, the greater the opportunity for intermolecular interactions, and thus the greater the boiling point. You should look up these boilig points! n-Pentane has a normal boiling point of approx. 36 ∘C ; n-heptane boils at 98 ∘C .
3. Octane has a high boiling point, because its molecule contains 8 Carbon atoms, and with increasing molecular weight of hydrocarbon its boiling temperature increases.

Answers
Answer:
For those who need it, the answers are N, O, R
Explanation:
To solve such this we must know the concept of redox reaction. Therefore, the given reaction is an oxidation and reduction reaction. The oxidation reaction is Mg [tex]\rightarrow[/tex] MgCl[tex]_2[/tex] and reduction reaction is HCl [tex]\rightarrow[/tex] H[tex]_2[/tex] .
What is chemical reaction?Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved. There are so many types of chemical reaction reaction like combination reaction, double displacement reaction.
Redox reaction is a chemical reaction where oxidation and reduction takes place simultaneously. Oxidation is loss of electrons and reduction is gain of electrons. The electron transfer from oxidant to reductant.
Mg + 2HCl [tex]\rightarrow[/tex] MgCl[tex]_2[/tex] + H[tex]_2[/tex]
Mg [tex]\rightarrow[/tex] MgCl[tex]_2[/tex] O
HCl [tex]\rightarrow[/tex] H[tex]_2[/tex] R
Therefore, the given reaction is an oxidation and reduction reaction.

Lead has an atomic number of 82. Which statement describes all neutral atoms and ions of lead?
Neutral atoms of lead must have 82 electrons. Ions must have 82 electrons, as well.
Neutral atoms of lead must have 82 neutrons, but ions can have more or fewer.
Neutral atoms of lead must have 82 protons. Ions must have 82 protons, as well.
Neutral atoms of lead must have 82 protons, but ions can have more or fewer.
Answers
The neutral atom of lead must have 82 protons while ions can have b or less than 82.
The atomic number of an element is the number of protons in the nucleus of the element.
Also, for neutral atoms, the number of protons equals the number of electrons.
In ionic form, the number of protons/electrons of an atom may vary and be different from that of the neutral form.
Positive charges mean that the ion has less proton than its neutral version while negative charges mean that it has more electrons than its neutral version.
Thus, the neutral atom of lead will contain an equal number of protons as the electrons while its ionic form can have more or less than 82 protons.

The statements which accurately describe the particles in differing states include:
Gases have the greatest kinetic energy.Energy is added to change from a solid to a liquid state. In a solid, particles are so closely packed that they can only vibrate in place.Gases have the greatest kinetic energy which explains why its particles
move very rapidly and randomly when compared to other states of matter.
Conversion from solid to liquid or liquid to gas requires more energy being
added.
The particles in solids are tightly packed with very restricted movements

D.
the potassium atom will lose an electron and become smaller as a cation, while the barium atom will gain an electron and become bigger as an anion.
Answers
Answer:
D (But as a heads up, you wrote barium instead of Bromine)
Explanation:
The Potassium atom will lose an electron since its valence shell only has one, while Bromine has 7 electrons in its valence shell. Potassium wants to get rid of its one electron, Bromine wants to gain that one electron to get a full shell.
Potassium will become a CATION with a positive charge (since it lost an electron), Bromine will become an ANION with a negative charge (since it gained an electron)
