Graph the data for the last time point at 75 minutes, and label each lines with the type of crystal

44. Match types of solid with each description. (Types of solids: molecular, metallic, ionic, covalent network) hard and brittle soft and brittle and nonconducting copper graphite

Question 12 of 20 Potassium chloride forms a solid made up of a highly organized set of positive and negative particles. Which term describes this solid? O A. An atom B. An ion C. A crystal D. A molecule

Answer the attached photo.

Give five practical applications each of crystalline and amorphous solids.

= STATES OF MATTER Understanding consequences of important physical properties ... Liquid A is known to have a higher vapor pressure and higher surface tension than Liquid B. Use these facts to predict the result of each experiment in the table below, if you can. experiment 35.0 mL of Liquid A are put in one sealed 5 L flask, and 35.0 mL of Liquid B are put in another sealed 5 L flask. The pressure in each flask is then slowly lowered with a vacuum pump. 35.0 mL of Liquid A are put in one sealed 5 L flask, and 35.0 mL of Liquid B are put in another sealed 5 L flask. The pressure in each flask is slowly increased by pumping in argon gas. O predicted outcome Eventually both liquids boil, A first and then B. Eventually both liquids boil, B first and then A. Neither liquid will boil It's impossible to predict whether eitherliquid boils without more information. Eventually both liquids boil, A first and then B. Eventually both liquids boil, B first and then A. Neither liquid will boil It's…

and compared to a pure substance. The melting point of an impure substance is usually A. higher B. over a broader range C. C lower D. over a narrow range

Chemistry Consider a liquid with a vapor pressure of 384 torr at 49.5°C and a vapor pressure of 1,245 torr at 129.3°C. What is the normal boiling point of this liquid in °C? (Hint: this is a two- step problem) Enter the normal boiling point of this liquid in °C to 1 decimal point.
