Answer:

10.5L

Explanation:

The volume in this question can be calculated by using the formula for gas law equation as follows:

PV = nRT

Where;

P = pressure (atm)

V = volume (litres)

n = number of moles (mol)

R = gas law constant (0.0821 Latm/molK)

T = temperature (K)

According to the provided information in this question:

P = 6.18 atm

V = ?

n = 2.35 moles

R = 0.0821 Latm/molK

T = 63°C = 63 + 273 = 336K

Using PV = nRT

V = nRT/P

V = 2.35 × 0.0821 × 336/ 6.18

V = 64.83/6.18

V = 10.49

V = 10.5L

Explain why lunar eclipses occur during a full moom
n200080 [17]

The answer to you're question is:

~A. Lunar eclipse occurs when the Moon passes directly behind Earth and into its shadow. This can occur only when the Sun, Earth, and Moon are exactly or very closely aligned with Earth between the other two. A lunar eclipse can occur only on the night of a full moon.

Hope this helps!!!

How many moles of 2H2 are formed from 3.64 mole of H2O?​
tatiyna

Answer: 2 H2 + O2 → 2 H2O, you get the same number of moles of water as H2, as long as you have 1 mole of O2. So, with 3 moles of H2, as long as you have 1.5 moles of O2, you will get 3 moles of H2O. In my opinion.
