After performing the reaction from Problem 16.37, the reaction flask is heated to 40°C and two of the products become the major products. When the flask is then cooled to 0°C, no change occurs in the product distribution. Explain why an increase in temperature causes a change in the product distribution and explain why a subsequent reduction in temperature has no effect.

What is the solubility of substance?

Calculate the estimated density of each ball. use the formula d = m/v where d is the density, m is the mass, and v is the volume. record your calculations in table a of your student guide. given that the density of water is 1.0 g/cm3, make a prediction about whether each ball will float in water. record your prediction in table a. what is the estimated density of the table tennis ball? record your answer to the nearest hundredth

Observation and experimentation have led many scientists to accept a theory about the origin of the universe. this theory is called the big bang theory. scientific evidence collected and observed by scientists around the world suggests that the universe is ever expanding from a hot and dense initial state. what makes this a scientific theory?
