Question Move the Electric Field slider to the on position. Two charged metal plates appear beside the molecule. Again, move the
electronegativity sliders to various positions. What causes the molecule to rotate?
o When the molecule's bond character is at its most ionic, it spins continuously between the plates due to its
momentum.
o When the molecule's bond character is at its most covalent, the molecule flips its orientation between the plates.
When the A atom's electronegativity is greatest, it becomes attracted to the negatively charged plate and rotates
toward it.
o When the partially negative side is near the negative plate, the molecule rotates because like charges repel and
opposite charges attract.

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.

Air can be considered a mixture. which statement does not explain why?
