Use these facts to predict the result of each experiment in the table below, if you can. experiment 25.0 mL of Liquid A are poured into a beaker. 25.0 mL of Liquid B are poured into another beaker. After 90 minutes have passed, the volumes V and VB of liquid in A each beaker are measured. 25.0 mL of Liquid A are put in one sealed 5 L flask, and 25.0 mL of Liquid B are put in another sealed 5 L flask.

11.Why do water molecules tend to stick to each other to form a liquid? A.Because of their bent shape, the oxygen nucleus of one molecule is unshielded and can attract the hydrogen nucleus of another. B.The exposed charge on hydrogen's protons are attracted to unshared electron pairs on oxygen atoms. C.The hydrogen atoms form negative ions that can make ionic bonds with oxygen. D.Water molecules can share electrons with neighboring molecules forming strong covalent bonds.

Use the phase diagram of X below to find your answer. pressure (atm) 0 atm بات solid 100 liquid 200 x gas temperature (K) Note: your answer must be within 2 atm of the exact answer to be graded correct. 300
A scientist is comparing the properties of the molecules HF and HCl. Unfortunately, he mixes up the beakers containing the molecules. To solve this, he decides to find the boiling point of each. He finds that the molecule in beaker A has a higher boiling point than beaker B. Which molecule is in beaker A and which is in beaker B? Explain your answer. ***Be sure to include the type of intermolecular forces experienced by BOTH molecules when explaining your answer.***
The chemical analysis of a water indicates the presence of cations in the following concentrations: Na+ 53 mg/L Mg2+36 mg/L K+ 72 mg/L Fe2+ 98 mg/L Mn2+15 mg/L A local softening company advertises that its softening unit has a capacity of 1000 meq. If water is used at the rate of 15 m³ per day, how frequently (i.e. how many times) will the unit have to be regenerated to provide the householder with soft water? (Na = 23, Mg = 24.4, K = 39, Fe = 55.85, Mn = 54.94 gms/mole) Answer: 105 Check
Consider the structures of dimethyl ether and ethanol. Which statements explain that the normal boiling point of dimethyl ether is 250 K, whereas the normal boiling point of ethanol is 351 K? a b Od H I. dimethyl ether has a lower boiling point because it has hydrogen bonding as its predominant IMF II. more energy is needed to overcome the stronger IMF of ethanol III. ethanol has more atoms, so it has stronger London dispersion forces than dimethyl ether I only I and II only ll only II and III only H-C-0-C-H H H Dimethyl Ether HH II H-C-C-O-H | | HH Ethanol
