Two models of the same compound are shown.

A top line labeled Model A saying C subscript 2 H subscript 4 O subscript 2. A bottom image with 2 C's connected by 1 black line. The left C has 3 H's connected to it by 1 black line each and the right C has 2 Os attached to it, the top O by two black lines and the bottom O by 1 black line. The bottom O also has an H attached to it by 1 black line.
A: In what way is Model B better than Model A?

B: Model B shows the types of elements in the compound, but Model A does not.

Model B shows the three-dimensional shape of the molecule, but Model A does not.

C: Model B shows how the atoms in the molecule are connected, but Model A does not.

D: Model B shows the number of atoms of each element in the molecule, but Model A
does not.

Iwll give extra points to who gets this for ! what type of reaction is this? ?

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.
