When diluting concentrated acids with water, wear appropriate ppe and slowly to to prevent a sudden release of heat or the creation of a fuming acid.

As changes in energy levels of electrons increase, the frequencies of atomic line spectra they emit

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

Mercury metal is poured into a graduated cylinder that holds exactly 22.5 ml the mercury used to fill the cylinder mass in 306.0 g from this information calculate the density of mercury
