Answer:
Because the moon rotates as it revolves around the Earth, we only ever see on side of the moon (That is why we call the other side the "dark side of the moon").
Hope this was the answer that you were looking for!!
1 mole of any gas under STP has volume 22.4 L.
Molar mass M(H2S) = 2M(H) + M(S)= 2*1.0 +32.1=34.1 g/mol
15g * 1mol/34.1g= 0.440 mol
0.440 mol*1L/22.4L= 9.85 L
<span> The volume of 15.0 grams of H2S at STP is 9.85 L.</span>
It is a completely true statement that <span>De Broglie hypothesized that all matter has some wave-like properties, even though it is made of particles. The correct option among the two options that are given in the question is the first option. I hope that this is the answer that has actually come to your desired help.</span>
