Molecules move faster in a warm glass of water they move slower in a cold glass of water
The first answer is B and the second answer is B
Answer:
The solution is not ideal and shows a positive deviation from Raoult’s law since Psolution (experimental) > Psolution (actual).
Explanation:
Number of moles of CS2 = 3.95g/76.13gmol-1 = 0.0519 moles
Number of moles of acetone = 2.43g/58.08gmol-1 = 0.0418 moles
Total number of moles = 0.0937 moles
Mole fraction of CS2 = 0.0519/0.0937 = 0.5538
Mole fraction of acetone = 0.0418/0.0937 = 0.4461
From Raoult’s law;
PCS2 = 0.5538 × 515 torr = 285.207 torr
Pacetone = 0.4461 × 332 torr = 148.1052 torr
Total pressure = 285.207 torr + 148.1052 torr = 433.3 torr
A: Na3PO4 + MnCl2 > Mn3(PO4)2 + NaCl
There are many pieces of evidence provided as strong evidence: fro example the Comparative anatomy of many species. <span>This evidence is based on compares of the the skeletons of humans, cats, whales, and bats, illustrating how similar they are even though these animals live unique lifestyles in very different environments. Another piece of evidence is </span><span>biochemistry of all living things on Earth. This is so because is incredibly similar. This shows that all of Earth’s organisms share a common ancestry.</span>
