Practicals Chemistry AQA A-level Rated A+ Required Practical 1 - titration and making a standard solution Making a standard solution 1. weigh the required mass of solid using a sample bottle on a 2 dp balance. 2. transfer the solid into a beaker using distilled water to wash it out- preventing any solid remaining in the sample bottle. 3. reweigh the sample bottle and work out the difference. 4. Add 100cm3 of distilled water to the beaker to dissolve the solid (small volume of water) using a...

BIOD 121 (Portage): Module 3 Latest Version Graded A+ Energy balance a state when one's energy intake is equivalent to the amount of energy expended Energy in equals energy out (calories consumed is burned through basic body functions + exercise energy balance positive energy balance occurs if more calories (energy) are consumed than expended examples of periods in life when you need to be in a positive energy balance state: pregnancy, childhood, and adolescence in growth spur...

Define Calorimetry Correct Answer-Determining the changes in energy of a system by measuring the heat exchanged with the surroundings Know how to calculate amount of energy released using E=mc(delta)T Correct Answer-E=energy, m=mass, c=specific heat, (delta T)=change in temp What is meant by a small calorie "c" and a food calorie "C"? Correct Answer-c=1 calorie=4.184 J, C=1000 little calories=4184 J When walking, an average person burns .453 C/(mile*pounds). How many C does a 150-po...

Know your significant figure rules Correct Answer-ALL zeroes between non-zero numbers are ALWAYS significant. ALL zeroes which are SIMULTANEOUSLY to the right of the decimal point AND at the end of the number are ALWAYS significant. ALL zeroes which are to the left of a written decimal point and are in a number >= 10 are ALWAYS significant. define calorimetry Correct Answer-the act of measuring heat required or evolved during a chemical process know how to calculate the amount of ener...

Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. The Latin word calor means “heat,” and meter comes from the Greek word meaning “to measure.” What do you think a calorimeter does? the measurement of heat 2. Where have you heard the word calorie before? What do you think a calorie is? a calorie is a measurement of how much energy it will take to break something down Gizmo Warm-up A calorimeter is an insulated container filled with a liquid, usually water.

Fundamentals of Calorimetry Lab date: 10/25/19 Purpose: Determining the specific heat capacity of the calorimeter, the enthalpy of the solution for calcium chloride and ammonium chloride. Background Calorimetry is the science of measuring heat. Plenty chemical and physical transformations involve energy transfer in the form of heat which is usually taken away from the water in reactions occurring in aqueous solutions. A calorimeter is an apparatus that is insulated and prevents heat from...
