Panacetin is a mixture of three components: sucrose, aspirin and tylenol. To determine the arrangement of layers, you must research on the densities of the components. The densities of sucrose, aspirin, and tylenol are 1.59 g/mL, 1.4 g/mL and 1.26 g/mL. The more dense the component, the farther it sinks to the bottom. Thus, the topmost layer is tylenol, followed by aspirin, and the bottom layer is sucrose. <em>Therefore, aspirin is placed in the second layer.</em>
Answer:
Volume and density are inversely related
Answer: One major strategy by which plants adapt to temperature change is to decrease the degree of unsaturation of membrane lipids under high temperature and increase it under low temperature. ... This pattern of changes in membrane lipids was distinct from that occurring during slow alterations in temperature.
Explanation: I found this answer from goggle
We first calculate the number of moles of K2CrO4 by multiplying the volume with the molarity.
n = (25/1000) x (3 M) = 0.075 mol K2CrO4
Then, from the balanced chemical equation, each mole of K2CrO4 will produce 1 mole PbCrO4 with molar mass of 323.2 g/mol.
(0.075 mol K2CrO4)(1 mol PbCrO4/1 mol K2CrO4) x (323.2 g/mol)
= 24.24 grams PbCrO4
Answer:
5 mol H₂. this is the answer bro all the best for your test/exam
