1. explain how you determined the polarity of all your compounds by first predicting the polarity of water, and then mixing different solutes and solvents to find the polarities of the other substances. 2. which of your polarity and solubility predictions were correct? 3. create three additional combinations of compounds from the materials in your experiment. without preforming tests, determine if your chosen solutes and solvents would be soluble or insoluble. explain how you can predict solubility without testing. 4. were any of your substances difficult to identify as polar, nonpolar, or ionic? explain. 5. predict the polarity and molecular structure of formaldehyde, a compound used to preserve animal specimens, and ammonia, a compound used in many household cleaning products. 6. based on their polarity, which compounds from your experiment could mix with formaldehyde and ammonia?

(04.05 hc) analyze the given diagram of the carbon cycle below. an image of carbon cycle is shown. the sun, a cloud, two trees, one on the left and the other on the right, an animal, lake, and a factory are shown in the image. an arrow is shown from the sun towards the left tree marked a. the sun is marked b. there is an arrow from the air above the clouds, marked c, towards the left tree. an arrow from a location close to the ground marked d points towards dead organisms, which is a label under the animal. an arrow marked e points from the right tree straight up to the clouds. an arrow marked f points from the animal straight up to the clouds. an arrow marked g points from the factory towards the air above the clouds, c. there is an arrow pointing from the air to the lake labeled carbonates in water, an arrow pointing down from dead organisms to fossils and fossil fuels, and an arrow from fossils to the factory. part 1: which compound does c represent? part 2: name a process that could release this compound into the air. part 3: explain how the elements that form it are conserved during the carbon cycle. use complete sentences to explain your answer.
