One property of metalloids not shared with metals or nonmetals is that metalloids are _________.

One property of metalloids not shared with metals or nonmetals is that

metalloids are they are shiny like metals and brittle like non-metals.

Metalloids are elements which have some intermediate similarities to

metals and non metals. They are neither good or bad conductors of heat

and electricity and they exist as solids at room temperature.

Examples of metalloids include boron. silicon, germanium etc and they are

brittle and shiny elements which gives them a distinctive physical

appearance.

Observe the activity in your classroom. You can observe people, objects in the room, parts of your actual classroom, to begin noticing changes in matter. Collect data for two examples of changes in matter. Use the Changes in Matter to determine if your examples are physical or chemical changes. Your answer should include a description of each food preparation, as well as evidence for which type of change it is. You can use this format:

students set up three trials of an experiment to test the effect of the amount of water on beam plant growth. In each trial, five plants each receive one of three amounts of water. after one week, students measure the change in each plant's height. The table summarizes their data.

The accepted value for R is 0.08206 L·atm/K·mol or 8.314 L·kPa/K·mol, depending on the unit of pressure used. (Your answer may differ slightly due to rounding.)

A chemist mixed two substances together: a colorless liquid with a strong smell and a white solid with no smell. The substances’ repeating groups of atoms are shown above on the left. After they were mixed, the chemist analyzed the results and found two substances. One ending substance had the repeating group of atoms shown above on the right.

Is the ending substance the same substance as the colorless liquid? What happened to the atoms of the starting substances when the ending substances formed? Be sure to explain your answers to both of these questions.

A student determined that a 50mL sample of an unknown liquid had a density of 1 g/mL. A 100mL sample of the same liquid would have a density of 2 g/mL. True or false

A space shuttle is covered with two layers of carbon. The two layers are the same size and have the same number of molecules. When the space shuttle is sitting on the ground, the layers do not touch, as shown in the diagram above. When the space shuttle takes off, the layers move so that they are touching. Use the information in the diagram to answer the question.

How does the temperature of the outer layer compare with the temperature of the inner layer before the layers touch? What will happen after the layers have been touching for a while?

A.Before the layers touch, the outer layer is hotter than the inner layer. Once the layers are touching, the outer layer will transfer kinetic energy to the molecules in the cooler inner layer until both layers reach the same temperature, which will be in between their starting temperatures.
B.Before the layers touch, the outer layer is hotter than the inner layer. Once the layers are touching, the cooler inner layer will gain kinetic energy until the molecules of both layers have an energy of 90, because hotter things increase the temperature of cooler things.
C.Before the layers touch, the outer layer is cooler than the inner layer. Once the layers are touching, the inner layer will transfer kinetic energy to the molecules in the cooler outer layer until both layers reach the same temperature, which will be in between their starting temperatures.
D.Before the layers touch, the layers are different temperatures. Once the layers are touching, kinetic energy and cold energy will transfer between the molecules in the two layers until both layers reach the same temperature, which will be in between their starting temperatures.
