Answer:
acid turns blue litmus red and base turns red litmus blue
Boiling point of cyclohexane at 620 mm hg?
Standard atmospheric pressure is 760 mm Hg. Boiling point at 760 mm= 80.74˚C
A liquid boils when its vapor pressure is equal to the atmospheric pressure. The vapor pressure of a liquid is proportional the absolute temperature of the liquid.
As the atmospheric pressure decreases, less vapor pressure is needed to cause the liquid to boil. Less vapor pressure means lower temperature.
The boiling point of cyclohexane at 620 mm Hg is less than 80.74˚C

Answer:
There is no chemical symbol for paper since it is not an element but rather a mixture of several different compounds. Mixtures in two or more phases are heterogeneous mixtures.
Explanation:
Answer:
Researchers at the NWS use a mathematical formula to calculate wind chill. In that formula, the wind speed in miles per hour (v) is subtracted from the air temperature in degrees Fahrenheit (T). It can be used in temperatures below 50°F and wind speeds above 3 mph.
