Question 20 (3 points) Why is the moon visible? Question 20 options: It is on fire. It reflects sunlight. Earth lights it up. It
alexgriva [62]

20. Answer is "it reflects sunlight".<span>

<span>The moon is </span>not a star<span> <span>as sun. Hence, </span></span>moon can't produce light by itself<span>. The only reason that we can see the moon is </span>it reflects the sunlight<span>. According to the distance from the sun to the moon, the light reflection can be varied.</span>

21. Answer is "Jupiter".

Asteroid belt<span> <span>is a </span></span>region which is located between Mars and Jupiter and consists of asteroids and minor planets.<span> This asteroid belt has the </span>4%<span> <span>as the mass </span>of our moon. Due to the </span>Jupiter's strong gravity<span>, it is </span>prevented a forming of new planet by this asteroid belt.

22.<span> Answer is "</span>they are equal".

The period of revolution is the time which is taken by a mass to go completely one round around another mass. For moon, the period of revolution is 27 days.<span>
The period of rotation</span> is the time taken by a mass to complete one round around its own axis. It is about 27 days for moon. 

</span>23.<span> Answer is "</span>The moon is in Earth's shadow".

<span>Lunar eclipse happens when </span>Sun, Earth and moon are directly aligned each other <span>and Earth is located in between the Sun and the moon. </span>Then the moon is covered by the Earth's shadow.

24.<span> Answer is "</span>In a solar eclipse, it is Earth that is caught in the umbra of the moon. In a lunar eclipse, it is the moon that is caught in the umbra of Earth".

In total lunar eclipse, Earth is located between Sun and the moon and they are directly aligned to each other. The moon is totally covered with the Earth's shadow.
Total solar eclipse can be seen when the moon is located between sun and Earth by completely covering the sun. 

25. According to the given choices, we can get "Apollo"<span> as the answer.

Apollo 8 is the first manned mission to the moon. From that there were several manned mission including <span>first manned landing on the moon. The Apollo program was conducted by USA.</span> </span>

A geochemist in the field takes a 36.0 mL sample of water from a rock pool lined with crystals of a certain mineral compound X.
NeTakaya

Answer:

solubility of X in water at 17.0 ^{0}\textrm{C} is 0.11 g/mL.

Explanation:

Yes, the solubility of X in water at 17.0 ^{0}\textrm{C} can be calculated using the information given.

Let's assume solubility of X in water at 17.0 ^{0}\textrm{C} is y g/mL

The geochemist ultimately got 3.96 g of crystals of X after evaporating the diluted solution made by diluting the 36.0 mL of stock solution.

So, solubility of X in 1 mL of water = y g

Hence, solubility of X in 36.0 mL of water = 36y g

So, 36y = 3.96

   or, y = \frac{3.96}{36} = 0.11

Hence solubility of X in water at 17.0 ^{0}\textrm{C} is 0.11 g/mL.

What is the density (g/L) of NH3 at 105 kpa and 25 C ( 0.721 g/mol)?
jenyasd209 [6]

Answer:

0.721 g/L

Explanation:

Ideal gas equation ->PV= nRT   ; n= mass (m)/ molar mass (M);

densitiy= mass (m)/ volume (V)

PV= (m/M)*RT  -> PVM= mRT   -> PM/RT= m/V   -> PM/RT=d

We need to put in SI units

105 Kpa= 1.04 atm

25°C= 298 K

d= (1.04 atm * 17 g/ mol)/(0.0821 * 298 K) = 0.721 g/L
