The chemical reaction shown below is carried out in a coffee cup calorimeter . A student mixes 10.0 mL of 0.100 M H 2 A(aq) and 20 mL of 0.100 MNaOH * (aq) , both initially at 25°C. The student records the highest temperature of 40.C for the reaction . H 2 A(aq)+2NaOH(aq) Na 2 A(aq)+2H 2 O(l) AH = ??? KJ/molx a. What indicates that this is an acid -base reaction ? Explain your answer . B. Determine the amount of energy involved in the reaction in the coffee cup calorimeter . The density of the resulting solution is 1.00g / m * L and has the same specific heat capacity as water , 4.2 J/ g °C c. Determine the enthalpy of the reaction , in kJ/mol r* n

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
