I. The solubility of NaCl at 25 degrees C would be between the solubilities at 20 and 30 degrees C. A reasonable answer would be 36 grams/100 g water
ii. From the table, it’s clear that the salts are more soluble at higher temperatures, indicating that an increase in temperature increases solubility.
iii. At 50 degrees C, a saturated ammonium chloride solution will have 50.6 grams of salt per 100 g water. At 20 degrees C, the solution can hold only 37.3 grams of salt per 100 g water. Thus, 13.3 grams of salt will precipitate per 100 grams of water.
Carbon dioxide (CO2)
Argon (Ar)
Hydrogen (H)
Helium (He)
Answer:
B. The pressure has increased
Explanation:
Answer:
The exact molecular mass is 18.01528 g/mol
Explanation:
Find this by adding the molecular masses of two hydrogen atoms and one oxygen atom.
