100 /results heat energy, q, is calculated by multiplying the mass of the object in grams, m, by the change of temperature, mδt, and the specific heat, cp, of the material. q = mδt(cp) calculate the heat lost from the bread at each interval. assume that the specific heat capacity of bread is 2.73 j/g °c. calculate the heat gained by the water at each interval. assume that the specific heat capacity of water is 4.19 j/g °c. based upon the results in questions 1 and 2, formulate a hypothesis regarding the transfer of heat between the bread and the water. identify at least one improvement that could be made to this experiment. justify your response in two or more complete sentences. what other household items could be used with your calorimeter? do you expect to get a different result? justify your response in two or more complete sentences. submission requirements title of lab: data tables: questions/results:

Where are each of the three particles located within the atom?

Ineed someone to see if my answers are correct! if any are wrong let me know what the correct answers would be and how to get that answer! 1. how many moles of sodium chloride are in 28 grams od nacl? a. 265 mole naclb. 856 mole naclc. 479 mole of nacld. 1.2 mole nacl < my choice2. 734 grams of lithium sulfate (li2so4) are dissolved to make 2500 ml of solution what is rhe molaratiy? a. 2.67 mb. 4.56 mc. 3.89 m < my choiced. 1.78 m3. how many grams of cacl2 would be dissolved in 3.0 l of a 0.50 m solution of cacl2? a. 250 g cacl2 b. 166.5 g cacl2c. 113.65 g cacl2d. 98 g cacl2 < my choice4. suppose you had 58.44 g of nacl and you dissolved it in exactly 2.00 liters. the molarity if the solution would be 0.5 mtrue < my choicefalse 5. i would need 22g of naoh to make a 3.0 m solution using 250 ml of solvent. true < my choicefalse6. identify the solute: you have a .0195 m solution made from using 6.5 g of solute and 3 l of solvent. identify the solute by solving for molar weight. a. the solute is nacl because the molar weight is 58.43 g/mol < my choiceb. the solute is h2so4 because the molar weight is 98.06 g/molc. the solute is cacl2 because the molar weight is 111.11 g/mol

How many mmols of tris-hcl are there in 100 ml of a 100 mm tris-hcl buffer solution at ph 8.1? note that the 100 mm refers to the sum of tris and tris-hcl concentrations?
