1. 2. At a given temperature T and pressure P, a person's lung holds a set volume of V of air. Given that air is roughly 20% oxygen, how many moles of oxygen are in his lungs? Answer: 0.2 PV/RT Electrolysis is conducted on 1 L of 0.4 in NaCl solution leadingto the the evolution of chlorine gas at one of electrodes. How many moles of chlorine gas is involved Answer: 0.2 mol

O CHEMICAL REACTIONS Predicting the products of dissolution Jay 0/5 The names and chemical formulae of some chemical compounds are written in the first two columns of the table below. Each compound is soluble in water. Imagine that a few tenths of a mole of each compound is dissolved in a liter of water. Then, write down in the third column of the table the chemical formula of the major chemical species that will be present in this solution. For example, you know water itself will be present, so you can begin each list with the chemical formula for water (H,O). Note: "major" chemical species are those present in concentrations greater than 10 6. mol/L. major species present when…

Round each of your answers to the nearest m/s. Note: your answers must be within 25 m/s of the exact answers to be graded correct. What is the most likely speed of a Ar atom in this sample? What higher speed is only half as likely as the most likely speed? What higher speed is only 10% as likely as the most likely speed? Explanation Check 2021 McGraw-Hill Education.
