We use the Raoult's Law to answer this question.
Partial Pressure = Mole Fraction*Total Pressure
When concentration is expressed in ppm, it means 'parts per million'. So, there can be 0.67 mol of ozone per 10⁶ mol of mixture.
Mole fraction = 0.67/10⁶ = 0.67×10⁻⁶
Partial pressure = 0.67×10⁻⁶(735 torr) = <em>4.92×10⁻⁴ torr</em>
Note: Although the video is not provided in this question, it is not needed to answer the question.
Answer:
B) It does not deflect at all
Explanation:
Since both half shells contain opposite charges, the two shells become electrically neutral when they are brought together and the electroscope discharges. On separating the two half shells again, the needle does not deflect because the half shells have now lost their charges to become neutral.
Answer:
sound travel fastest through solids this is because molecules in a solid media much closer together then throws in a liquid or gas flowing sound ways to travel more quickly throw it in fact sound waves travel over 17 times faster throw Steel then through air
Answer:
Nanotechnology is the term given to those areas of science and engineering where phenomena that take place at dimensions in the nanometre scale are utilised in the design, characterisation, production and application of materials, structures, devices and systems.
Answer:
160 m
Explanation:
distance covered in 1 s = 8 m
therefore, distance covered in 20 s = 8 * 20 m = 160 m
