Mary wants to model a volcanic eruption for her 5th grade science fair project. She combines baking soda (NaHCO3) and vinegar (HC₂H₂O₂) to create the eruption. The eruption bubbles up and spills over the side of her volcano. Mary formed sodium acetate (NaC₂H₂O₂), water (H₂O) and carbon dioxide (CO₂) in the simulated eruption.
Calculate the pH of each of the following solutions, and label each as acidic, basic, or neutral. Solution pH DIS [H₂O+] = 1.0 x 10-M [H₂0+] <= 0.01 M [H₂O+] = 7.3 x 10- M lad msip Acidic/Basic/Neutral
Write the balanced NET ionic equation for the reaction when AICIs and NaOH are mixed in aqueous solution. If no reaction occurs, simply write only NR. Be sure to include the proper phases for all species within the reaction.
A known reaction has Change in U= 38 kJ/mol. The reaction is done at constant pressure and you measure the amount of work done to be w=+2 kJ/mol. What is q in kJ/mol?
When 200.0 g water goes from a temperature 10.0°C to 40.0 °C, is heat absorbed or released? Calculate the amount of heat absorbed/released.
I need answer nowUse Concepts A lab group was given a candle, a match, a strip of cloth, tongs, and a metal can. They were asked to use these materials to model conduction, convection, and radiation. Develop a procedure they could use to do this.
Are there substances in the lab that have bonds that are not strictly ionic, covalent, or metallic? Explain your answers.
