In image 1, the moon is in a certain spot in its tilted elliptical orbit, so it is effectively under the Earth from the Sun's perspective. But in image 2, The moon is actually behind the Earth from the Sun's perspective.

Explanation:

I kinda' explained in my answer

In image 2, the lunar eclipse because the earth's shadow falls on the surface of the moon when Earth, moon, and sun all are aligned in a straight line.

A lunar eclipse usually takes place when the Moon moves into the shadow of the earth. This eclipse happens only when the Sun, Earth, and Moon are exactly aligned with Earth between the other two, which can occur only on the night of a full moon when the Moon is close to the lunar node.

When the moon is eclipsed by the Earth, it gets on a reddish color that is caused by the planet when it fully blocks direct sunlight from reaching the Moon's surface, as only the light reflected from the lunar surface has been refracted by the atmosphere of the earth. Due to the Rayleigh scattering of blue light, this light appears reddish.

A total lunar eclipse lasts up to nearly 2 hours, lunar eclipses are safe to view. Therefore, image 2 represents the lunar eclipse.

Resonance and transmission​ are the two aspects of sound waves that the student observe.

Resonance is defined as when one object vibrating at a specific natural frequency and compels the second object into vibrational motion.

We know that sound waves required medium and transmit from one place to other by transferring the sound energy to its neighbouring particles so we can conclude that Resonance and transmission​ are the two aspects of sound waves that the student observe.

The study of electricity in chemistry.

4 moles of NaOH is present in the given 160 grams of NaOH.

Moles of any substance will be calculated as:

n = W/M, where

W = given mass of NaOH = 160 grams (given)

M = molar mass of NaOH = 40 g/mole

Moles of NaOH is calculated as:

n = 160g / 40g/mol = 4 moles

Hence, moles of sodium hydroxide (NaOH) is 4 moles.

In the parallel circuit, each lamp will receive 100 volts.

The equivalent resistance of the parallel circuit is the inverse sum of the resistance of the two resistors in the circuit. This is as a result of different current flowing in each resistor parallel circuit arrangement.

The equivalent resistance is calculated as follows;

1/R = 1/10 + 1/10

1/R = 2/10

R = 10/2

R = 5 ohms

I = V/R

I = 100/10 = 10 A

V = IR

V = 10 X 10 = 100 V

Generally, for a circuit in parallel connection, same voltage will flow in each resistor of the circuit while different current will flow in the resistors.

Thus, the correct statement is, "Each lamp will receive 100 volts".

Temperature factor plays the most important role in the decomposition reaction of magnesium oxide.

Those reactions which are exothermic in nature or release heat during the reaction are spontaneous reactions.

Given decomposition reaction of magnesium oxide is:

MgO(s) + 601.7 kJ → Mg(s) + ½ O₂(g)

From the above reaction, it is clear that during the decomposition of magnesium oxide heat is absorbed. So, for the feasible decomposition of compound accurate temperature is wanted.

Hence, correct option is temperature.

Answer:

39 mol AgNO3

Explanation:

We have the equation 4HNO3 + 3Ag -----> 3AgNO3 + NO + 2H2O

We want to calculate the number of silver nitrate (AgNO3) moles that would be produced from 52 moles of nitric acid ( HNO3 )

We can calculate this by using mole ratio as well as dimensional analysis.

The mole ratio of Silver nitrate to nitric acid based on the balanced equation is 3AgNO3:4HNO3.

Using this we can create a table: The table is attached.

Breakdown of the table.

The moles of nitric acid cancel out and we multiply 52 by 3/4 to get 39 moles of Silver nitrate.

Answer:

V2 = 33L

Explanation:

KNOW THAT:

V1 = 30L

P1 = 2.0atm

T1 = 27 + 273.15 = 300.15k (it's help to be in Kelvin)

P2 = 2.0 atm

T2 = 54 = 273.15 = 327.15

V2 = ?

We have an equation: P1V1/T1 = P2V2/T2

Multiply both side for T2 to remove it, divided both side for P2 to remove it. So we can left with V2, and that is what we want to find.

T2P1V1/T1P1 =>> V2= 33L

The original pressure of a gas that has 5.00 L of its sample expanded to 15.0 L, at which point the pressure is measured to be 0.720 atm is 2.16atm.

The pressure of a gas can be calculated using the Boyle's law equation as follows:

P1V1 = P2V2

Where;

P1 × 5 = 15 × 0.720

5P1 = 10.8

P1 = 10.8 ÷ 5

P1 = 2.16atm

Therefore, the original pressure of a gas that has 5.00 L of its sample expanded to 15.0 L, at which point the pressure is measured to be 0.720 atm is 2.16atm.

Taking into account the definition of Avogadro's number, 7.59×10²⁴ particles of C₈H₁₈ would be in 12.6 moles of octane.

Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023×10²³ particles per mole. Avogadro's number applies to any substance.

Then you can apply the following rule of three: If by definition of Avogadro's number 1 mole of C₈H₁₈ contains 6.023×10²³ particles, 12.6 moles of the compound contains how many particles?

amount of particles of C₈H₁₈= (6.023×10²³ particles × 12.6 mole)÷ 1 mole

amount of particles of C₈H₁₈= 7.59×10²⁴ particles

Finally, 7.59×10²⁴ particles of C₈H₁₈ would be in 12.6 moles of octane.
