Answer:
A for 1 and 4 B for 2 and 3 ..........
Answer:
Saturated solution = 180 gram
Explanation:
Given:
Solubility of Z = 60 g / 100 g water
Given temperature = 20°C
Amount of water = 300 grams
Find:
Saturated solution
Computation:
Saturated solution = [Solubility of Z] × Amount of water
Saturated solution = [60 g / 100 g] × 300 grams
Saturated solution = [0.6] × 300 grams
Saturated solution = 180 gram
Answer: yes
Explanation: Atoms can join together to form a molecule
Answer:
The model was the result of hundreds of years of experiments. however we have had modifications.
