Answer:
2
Explanation:
2 is the lowest and the most acidic, which turned it red
Answer:
1171.12 mL
Explanation:
Using the combined gas law equation;
P1V1/T1 = P2V2/T2
Where;
P1 = initial pressure (mmHg)
P2 = final pressure (mmHg)
V1 = initial volume (milliliters)
V2 = final volume (milliliters)
T1 = initial temperature (Kelvin)
T2 = final temperature (Kelvin)
According to the information provided in this question:
P1 = 300 mmHg
P2 = 140 mmHg
V1 = 400 mL
V2 = ?
T1 = 0°C = 273K
T2 = 100°C = 100 + 273 = 373K
Using P1V1/T1 = P2V2/T2
300 × 400/273 = 140 × V2/373
120000/273 = 140V2/373
120000 × 373 = 273 × 140V2
44760000 = 38220V2
V2 = 44760000 ÷ 38220
V2 = 1171.115
The new volume is 1171.12 mL
Answer:
Neutrons- 9 Electrons- 8
Explanation:
Protons equals electrons and since the atomic# of oxygen is 8, 8 is the proton and 8 will be the electrons a s well since it isn't an ion. You subtract 8 from the 17 to get 9 as the neutron.
Answer:
292 mL
Step-by-step explanation:
The pressure is constant.
The only variables are volume and temperature, so we can use <em>Charles’ Law.</em>
V₁/T₁ = V₂/T₂ Multiply each side by T₂
V₂ = V₁ × T₂/T₁
V₁ = 250 mL; T₁ = 300 K
V₂ = ?; T₂ = 350 K
V₂ = 250 × 350/300
V₂ = 292 mL
Answer:The top of the fractional distillation column will have a more volatile liquid as compared to the liquid at the bottom.
Explanation:
Fractional distillation is the method of separating liquids with different boiling points.For example,ethanol can be separated from water from a ethanol-water mixture.The component with a lower boiling point will pass in the column and collected first followed by higher boiling point component.Repeated vaporization and condensation results in the separation of the components in the mixture.
