Answer:
238 amu
Explanation:
(234 * 0.0001) + (235 * 0.0071) + (238 * 0.9928) = 238
False; Colloidal particles will not eventually settle out.
Answer:
1.02 × 10⁻³ g
Explanation:
Step 1: Given data
Number of moles of titanium (IV) oxide in 1 jelly bean (n): 1.28 × 10⁻⁵ moles
Step 2: Calculate the mass (in grams) corresponding to 1.28 × 10⁻⁵ moles of TiO₂
To convert moles to mass, we need a conversion factor. In this case, it is the molar mass of TiO₂: 79.87 g/mol.
1.28 × 10⁻⁵ mol TiO₂ × 79.87 g TiO₂/1 mol TiO₂ = 1.02 × 10⁻³ g TiO₂
Answer: It is number a
a. Cold is removed from the container of water until the rock, the container, and the water all reach the same final temperature.
