Explanation:

However, the brightness of a star depends on its composition and how far it is from the planet. Astronomers define star brightness in terms of apparent magnitude — how bright the star appears from Earth — and absolute magnitude — how bright the star appears at a standard distance of 32.6 light-years, or 10 parsecs.

Astronomers measures the luminosity of stars by determining the magnitude of brightness and distance from earth.Thus option C is correct.

Luminosity of a star is the total amount of energy radiated by them to a distance. The luminosity vary from star to star based on the distance to them.

Luminosity is basically measured in terms of brightness as observed from the earth. Stars will make a group in certain shapes and certain number called constellation. The overall brightness can be then higher for each constellation.

Astronomers define the brightness of stars by the apparent distance from the earth whereas the absolute magnitude is defined is terms of standard distance of 32.6 light years. Hence, the option C based on distance and brightness is correct.

Answer:

the scientific formula is C2H4O2

Explanation:

The cleavage of the compounds resulted in the fragments with varying stability. The most common fragment of acetic acid is [tex]\rm C_2H_4O_2^+[/tex].

The common fragments in the molecular compound are the species that result in the neutral ions adn electrons with the cleavage of the bonds.

Acetic acid is a weak acid in nature, and is composed of the carbon, hydrogen and oxygen elements.

The cleavage of the species in the acetic acid spectrum resulted are, [tex]\rm [COOH^+],\;[CH_3CO^+],\;[CH_2CO^+],\;[HCO^+],\;[CO^+],\;[CH^3^+][/tex].

The species, with the highest m/z ration, has been the most common fragment of the acetic acid. The m/z ratio of the following species is given in the table attached.

From the table, the highest ratio for the stability has been found with [tex]\rm C_2H_4O_2^+[/tex]. Thus, the most common fragment of acetic acid is [tex]\rm C_2H_4O_2^+[/tex].

Answer: The clumps, known as glacier mice, have been found to contain miniature ecosystems

Explanation: Because glaciers are in constant, if slow, motion and are frequently blasted by strong winds.

The clumps, known as glacier mice, have been found to contain miniature ecosystems. And even in freezing temperatures, scientists found, the inhabitants manage to thrive. In high winds glacier mice, which form when clumps of dust and organic debris develop a layer of moss over time, hop across vast sheets of ice.

These included springtails (small insect-like animals), water bears (also known as tardigrades, the only animals known to have survived in space), and roundworms. Globally, glacier mice are rare.

Baking soda is sodium bicarbonate, which requires acid and a liquid to become activated and help baked goods rise. Conversely, baking powder includes sodium bicarbonate, as well as an acid. It only needs a liquid to become activated. Substituting one for the other is possible with careful adjustments. Baking soda is strong. In fact, it is about 3-4x stronger than baking powder. More baking soda in a recipe doesn't necessarily mean more lift.

So, in general, atomic radius decreases across a period and increases down a group. Across a period, effective nuclear charge increases as electron shielding remains constant.

Explanation:

Moving from left to right across a period, the atomic radius decreases. The nucleus of the atom gains protons moving from left to right, increasing the positive charge of the nucleus and increasing the attractive force of the nucleus upon the electrons.

Structure V reacts fastest with trimethylamine in SN2 reaction. Owing to less steric crowding in the transition state and ease of cleavage of the R - I bond

The question is incomplete, the complete question is shown in the image attache to this answer.

SN2 reaction is a type of nucleophilic reaction in which the nucleophile attacks the substrate from the reverse side. This is a synchronous reaction because the leaving group departs as the entering group attacks simultaneously in a hypervalent transition state.

SN2 reaction is favored by structure V owing to less steric crowding in the transition state and the easy of cleavage of the R - I bond. Hence, structure V reacts fastest with trimethylamine in SN2 reaction.

The gain in mass by the negative electrode is the same as the loss in mass by the positive electrode. So the copper deposited on the negative electrode must be the same copper ions that are lost from the positive electrode.

Answer:

0.08 M

Explanation:

here...

1. water and a salt

2. Magnesium hydroxide reacts with HCl to produce a solution that is neutral.

3. titrant

4. 0.08 M

5. indicator

{quizlet: captncrun}

The concentration of sodium hydroxide is 0.08 M. The correct option is the second option 0.08 M

From the question,

We are to determine the concentration of sodium hydroxide

The given reaction is

HCl + NaOH → NaCl + H₂O

This means

1 mole of HCl is required to completely neutralize 1 mole of NaOH

To determine the concentration of sodium hydroxide,

We will use the formula

[tex]\frac{C_{A}V_{A} }{C_{B}V_{B}} = \frac{n_{A}}{n_{B}}[/tex]

Where

[tex]C_{A}[/tex] is the concentration of acid

[tex]C_{B}[/tex] is the concentration of base

[tex]V_{A}[/tex] is the volume of acid

[tex]V_{B}[/tex] is the volume of base

[tex]n_{A}[/tex] is the mole ratio of acid

[tex]n_{B}[/tex] is the mole ratio of base

From the give information

[tex]C_{A} = 0.10 \ M[/tex]

[tex]V_{A} = 40 \ mL[/tex]

[tex]V_{B} = 50 \ mL[/tex]

From the balanced chemical equation

[tex]n_{A} = 1[/tex]

[tex]n_{B} = 1[/tex]

Putting the above parameters into the formula, we get

[tex]\frac{0.10 \times 40}{C_{B} \times 50} = \frac{1}{1}[/tex]

Then

[tex]C_{B} \times 50 = 0.10 \times 40[/tex]

∴ [tex]C_{B}=\frac{0.1 \times 40}{50}[/tex]

[tex]C_{B}=\frac{4}{50}[/tex]

[tex]C_{B}=0.08[/tex]

Hence, the concentration of sodium hydroxide is 0.08 M. The correct option is the second option 0.08 M
