7. foam cup a has 36 ml of water that contain 2 moles of hcl at 20°c. foam cup b has 36 ml of water that contain 2 moles naoh of at 20°c. the contents of foam cup a are added to foam cup b and a chemical reaction occurs. the final temperature of the contents of cup b is 31°c. calculate the enthalpy change of the reaction. the density of each solution is 1g/ml. a.-1.66 kj b.-3.31 kj c.-6.62 kj d.-13.2

When an object falls through the air and encounters air resistance its overall speed will be than if it had not encountered air resistance? (one word answer)

When the water vapor cools it condenses select a number that represents his process on the

Both josef loschmidt and amedeo avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. neither scientist discovered “avogadro’s number” in the form we use it today (6.02 x 10 23). still, there’s a controversy over the name. research the contributions from these two scientists and read about how avogadro’s number got its name. briefly state what you think this number should be called, providing key details of each scientist’s contributions to this concept and a solid rationale for your case in naming the number.
