Answer:
about 0.7 g/mL
Explanation:
Density = mass ÷ volume
D = 5.29 g / (12.6 mL - 5.00 mL)
D = 5.29 g / 7.6 mL
D = 0.696052.... g/mL
D = about 0.7 g/mL
Answer:
The voltage delivered by a primary battery is unrelated to its size.
Answer:
633.5
Explanation:
The total presser is 650.00 mmHg, and it is collected over water, which at 19c is 16.5 mmHg. Therefore, to get the total pressure of H2 you would subtract the partial pressure of water from the total pressure.
650-16.5=633.5
Answer: Evaporation of salt water
Explanation: During the process of evaporating salt water which involves simple distillation, pure water is separated with salt molecules.
When heated water evaporates from the solution since it is less dense. When condensed it becomes pure water and salt is left out since it is more denser.
