Answer:
See explanation
Explanation:
If we look at the structure of X, we will discover that X is an organic compound. The compound will certainly have a much lower melting point than sand.
This is because, sand is composed of high melting point inorganic materials.
Hence, even though the researcher accidentally spilled some sand into the the beaker containing the crystalline substance X, he does not need to be perturbed since the melting point of X is much lower than that of sand
Only far from the Sun material condensed in the solar nebula, ice formed
Explanation:
The answer is 116 kJ . c - water's specific heat - 4.184 J/g⋅∘C . Then, you must provide enough heat to get all the water from liquid to steam.

Answer:
Explanation:
We collected the gas over water; to obtain the true pressure of the gas, we have to correct for the vapor pressure of water. We look up the vapor pressure of water at 24 ºC: 24 torr. The pressure of the evolved gas is, therefore, 738 −24 = 714 torr. 2. We want the molar mass of the
