In 2009, a team from Northwestern University and WesternWashington University reported the preparation of a new“spongy” material composed of nickel, molybdenum, andsulfur that excels at removing mercury from water. The densityof this new material is 0.20 g/cm3, and its surface area is1242 m2 per gram of material. (a) Calculate the volume of a10.0-mg sample of this material. (b) Calculate the surface area fora 10.0-mg sample of this material. (c) A 10.0-mL sample of contaminatedwater had 7.748 mg of mercury in it. After treatmentwith 10.0 mg of the new spongy material, 0.001 mg of mercuryremained in the contaminated water. What percentage of themercury was removed from the water? (d) What is the final massof the spongy material after the exposure to mercury?
3. (a) Estimate the fractional change in the volume of Earth's oceans due to an average temperature change of 1°C.
(b) Use the fact that the average depth of the ocean is 4.00x10^3 m to estimate the change in depth. Note that βwater=2.07x10^-4 (°C) ^-1.

Using the information contained in the table, what is the BEST explanation for the results?A The melting point of sodium chloride was not observed because ionic solids do not melt, whereas sugar, wax, and lard melted because they are softer than salt.B The melting points of covalently bonded solids tend to be lower than ionic solids. The melting point of sucrose was greater than the wax or the lard because sucrose has stronger bonds than wax or lard.C The melting point of sodium chloride was not observed because ionic solids are composed of positive and negative ions that do not melt; whereas, the…

- Marie Curie was born in Poland but studied and carried out her research in Paris. In 1903, she shared the Nobel Prize in Physics with H. Becquerel and her husband Pierre for their discovery of radioactivity. (In 1911 she received the Nobel Prize in Chemistry for the discovery of two new chemical elements, radium and polonium, the latter named for her homeland, Poland.) They and others observed that a radioactive substance could emit three types of radiation: alpha (), beta (), and gamma (). If the radiation from a radioactive source is passed between electrically charged plates, some particles are attached to the positive plate, some to the negative plate, and others feel no attraction. Which particles are positively charged, which are negatively charged, and which have no charge? Of the two charged particles, which has the most mass? Radioactivity. Alpha (), beta I(), and gamma () rays from a radioactive element are separated by passing them between electrically charged plates.arrow_forwardThere are four sketches below. The first sketch shows a sample of Substance X. The three sketches underneath it show three different changes to the sample. You must decide whether each of these changes is possible.

A patient heats 16 oz. of 22 o C water on the stove until it has absorbed 33 kcal of energy. He then mixes 2.0 oz. of the hot water with 1.5 oz. of room temperature whiskey (d = 0.94 g/cm3 , cs = 3.40 J/g o C, T = 22 o C).
