Zinc metal can be obtained from zinc oxide (ZnO) by reacting the oxide with the element carbon. The products of the reaction are Zn and CO2.
Wastewater flow in a sewer can be estimated by adding a known amount of tracer such as salt solution and measuring the salt concentration upstream and downstream of the point of addition.
What is your sampling rate in ml/min if you collected, over a four hour sample
A student mixed 75.0 mL of water containing 0.75 mol HCl at 25 degrees C with 75.0 mL of water containing 0.75mo of NaOH at 25 degrees in a foam up calorimeter. The temperature of the resulting solution increased to 35 degrees C.
