1) A compound is found to have (by mass) 48.38% carbon, 8.12% hydrogen and the rest oxygen. What is its empirical formula?

doug began preparing laboratory surface disinfectant from chlorine bleach. he put on a chemical resistant apron and gloves and then removed the bleach container from the special chemical cabinet. he carefully placed the container on the laboratory benchtop and began to add the chlorine bleach to distilled water. nearby workers began complaining of burning eyes. doug was reprimanded by the supervisor. Explain why.

Why are ducks waterproof? It’s because they produce copious amounts of oils from their uropygial glands and spread it across their feathers. In this exercise, we’ll be investigating the molecular structure of one of these preen oils to determine how it keeps ducks dry. Q.5 - Preen oil is actually a complicated mixture of many different organic compounds, such as the structure seen previously.. Ornithologists have determined that birds often use preen oil compounds for scent recognition. Below, several different chemicals isolated from preen oil are shown, along with their vapor pressures at room temperature. p-cymene has the highest vapor pressure, meaning it is the most easily evaporated compound of the three listed. Explain why p-cymene has a higher vapor pressure at room temperature compared to the other compounds. Make sure to explain what holds the p-cymene in the sample. (Image attached)

Assume the data below was collected for two different sample solutions using the same experimental procedure you carried out. Based on the two lines shown below, which solution (orange data points or blue data points) corresponds to the sample that would look DARKER in terms of how much light goes through the glass. 0.9 y= 4.7713x - 0.0728 R0.99953 0.8 0.7 0.6 0.5 0.4 0.3 0.2 y1.414x - 0.0546 R0.99642 0.1 0.02 0.04 0.06 0.08 0.1 0.12 0.14 0.16 0.18 0.2 0.1 [Concentration, M] orange data points (lower line) blue data points (upper line) Absorbance

Is the following statement true or false? If you think the statement is false, rewrite it to make it true: Closed loop manufacturing involves the recycling of wastes so they are not released back into the environment. NOTE: This question is related to green chemistry in the industry.

Each sketch below shows three objects with an electric charge. In each case, decide whether there is a net force acting on the object outlined in green. If there is a net force, decide whether it pushes the green-ring object to the left or right. Then select the appropriate button under the sketch. For example, if there is a net force pushing the green-ring object in the first sketch to the left, select the left button under the first sketch. If there is no net force on the green-ring object in the second sketch, select the middle button under the second sketch. And so on. ola -2 +3 -2 -2 I Don't Know Submit 2022 McGraw Hill LLC.
