A solution of acetic acid (CH3COOH and water that is 75.% acetic acid by mass is boiling at 105.2 °C. The vapor is collected and cooled until condenses to form a new solution. Calculate the percent by mass of acetic acid in the new solution. Here's some data you may need: ormal vapor pressure density boiling point at 105.2 °C 118, °C 593. torn 1.1 mL acetic acid 1 00 910. torr 100. °C water ml Be sure your answer has the correct number of significant digits. Note for advanced students: you may assume the solution and vapor above it are ideal 10 X

24 points and brainliest to anyone who can answer under 10 minutes with best ! the table below shows the role of different substances during photosynthesis. substance role during photosynthesis glucose stores chemical energy water combines with glucose to form carbon dioxide chlorophyll traps sunlight which of the following statements would correct one of the roles listed in the table? glucose combines with carbon to form water. chlorophyll reacts with light to produce carbon dioxide. water combines with carbon dioxide during photosynthesis. chlorophyll stores chemical energy needed for photosynthesis.

Which of the following observations indicates that there is a small, dense, positively charged part in the center of an atom? some uncharged particles are scattered by a gold foil. all uncharged particles are attracted towards a gold foil. all positively charged particles pass straight through a gold foil. some positively charged particles bounce back from a gold foil.

Freezing and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.
