The mass of the toy hammer is 67.4g. Calculate the volume from the before and after pictures below. Then calculate the density of the hammer. 13 g/mL 17.325 g/mL 16.85 g/mL 15 g/mL Use the information below to calculate the density: Mass: 155.2 grams 22.51 g/mL 19.4 g/mL 8 g/mL 25 g/mL Volume: Look at the graduated cylinders below and determinethe volume of the little toy man. Then calculate his density based on a mass of 745g. 460 g/mL 560.62 g/mL 465.62 g/mL Quartz can scratch feldspar but not topaz. Calcite can scratch flourite but not apatite. Which of the following statements is true? feldspar is harder than apatite and softer than quartz. topaz is harder than felspar but softer than fluorite Which of the following statements is true? This student is testing a quartz crystal for a certain property. What property are they testing? streak malleability hardness luster metal nonmetal metalloid Mrs. Ruble found these pieces of material outside while riding her dirt bike one weekend. She discovered they had luster and were very brittle. She tested to see if they conducted electricity but found they did not conduct electricity as good as copper wire. Mrs. Ruble thinks this material is a______________. Mr. Bellman found this substance at school and was trying to determine if it was a metal, nonmetal, or metalloid. It has luster, conducts electricity, and is very malleable. Mr. Bellman is thinks this substance must be a___________________. metal nonmetal metalloid Mrs. Ruble was conductinga test to see how this objectreacted to electricity. Aftertesting it, she decided it was a very dull, very brittle semiconductor.This object must be a: metal nonmetal metalloid The wire in this picture are made from a material that is ductile and able to be stretched into thin wires. The material is most likely a: metal nonmetal metalloid Mr. Bellman was examining the gas in a neon light. Upon examining the gas, he noticed it was light red, it was not malleable or ductile. The gas is most likely a: nonmetal metal metalloid Mr. Bellman found a piece of metal and is trying to determine what is made of. He weighed it on a scale and found the mass to be 26.4g. He found the volume to be 3mL. Calculate the density and help Mr. Bellman determine what the substance is made of. Nickel Steel Mr. Bellman took some mineral samples and began scraping them across a streak plate to see what color powder they left behind. Mr. Bellman was testing the minerals for: conductivity luster hardness streak Mrs. Ruble measured the mass of two different minerals and found they had the same mass.Which statement is most likely true about theminerals? they are made of the same stuff. They have the same mass and volume. They do not necessarily have the same density. they are exactly the same. Luster, density, malleability, ductility, are all examples of: metalloids chemical properties of matter minerals physical properties of matter |
