To objects (A and B) of the same temperature are in contact with each other? Which statement is true. A. Heat transfers from object A to object B, because molecules from a collide with those from B.
B. No heat transfers because there are no collisions between the molecules of the objects
C. Heat transfers from object B to object A, because molecules from B collide with those from A
D. Although the molecules collide, no heat transfers because there is no temperature difference between the objects

Describe the interaction that occurs between two objects with the same electrical charge.

Plzz a sample of table sugar (sucrose, c12h22o11) has a mass of 7.801 g. ● a) calculate the number of moles of c12h22o11 in the sample b) calculate the number of moles of each element in c12h22o11 (number of moles of c, number of moles of h & number of moles of o) in the sample. (use your answer from part a as your starting point.) show your work and highlight your final answer. calculate the number of atoms of each element in c12h22o11 (number of atoms of c, number of atoms of h & number of atoms of o) in the sample. (use your answers from part b as your starting for each element.) show your work and highlight your final answer.
