Which option explains how purple pigments make some flower petals purple? Purple pigment molecules absorb purple light. After absorbing the purple light, these molecules send part of their purple color out. Thus, the petals appear purple.

Purple pigments absorb all colors of light except purple. Purple light is reflected. The only light that arrives to a person’s eyes from the petal is purple.

Purple pigments absorb all colors of light, including purple. Purple is the base color of the flowers. When all colors of light are absorbed, the flowers look purple.

Purple pigments absorb purple color and reflect all other colors back. Because only purple light is kept in the purple pigment, it appears purple.

What are the percent by mass of copper in penny lab

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.
