While studying states of matter and kinetic energy, the students in Ms. Sanders' class set up the experiment described above. Before laying the paper towels on the plastic bags, Ms. Sanders asked the students to make a prediction about the rate of evaporation Pick the statement that is MOST accurate about what is expected to occur. A) Water will evaporate from both paper towels but at different rates. B) The more surface area of the paper towel exposed to air, the faster the rate of evaporation C) Water will not evaporate from the paper towel laying over the plastic bag filled with cold water. D) The energy from the hot water in the plastic bag will increase the rate of evaporation from the paper towel

Follow the steps provided in the simulation to add water to the graduated cylinder, select one of the three samples (copper, silver, or gold), set its mass to the values given in the statements below, and calculate its density. here is a summary of the steps required: add water by clicking and holding prepare a known volume of water button. until the desired volume of water has been added. if more than the desired volume is added, click the reset button. button and redo the procedure. a single click will add about 21.0 ml of water. to set the mass, click and hold weigh out metal button. until the desired amount of metal is added to the weighing pan. once the desired mass of the metal is added, release the button. transfer the metal to water and then click on calculate density button. to see how the density is calculated using water displacement to measure the volume of the solid. to save time you can approximate the initial volume of water to â±1 ml and the initial mass of the solid to â±1 g. for example, if you are asked to add 23 ml of water, add between 22 ml and 24 ml. which metals in each of the following sets will have equal density? check all that apply.

Acompound has a molecular weight of 12.124 atomic mass units and the empirical formula c3h40. what is the molecular formula of the compound?

If a gas has an initial pressure of 101kpa and a volume of 10l, then it expands to a volume of 20l, what is the new pressure?
