250 kJ/87.9 KJ per mole Cl2 * 71g/mole= 202 g It is D for plato users
Density = mass / volume
therefore, density = 22/42 = 0.524 kg/m3
Option C. A compound being separated into 2 elements represents a chemical change.
Molecular weight of oxygen is 15.998g therefor 1.5(2*15.998)=47.994g
Answer:
C sound waves
Explanation:
Information processing starts with input from the sensory organs, which transform physical stimuli such as touch, heat, sound waves, or photons of light into electrochemical signals. The sensory information is repeatedly transformed by the algorithms of the brain in both bottom-up and top-down processing.
