14 Students are given a solid sample and asked to determine whether the sample is

an element, compound, or mixture. One

student observes that the sample is:

• made up of particles of different

colors, sizes, and shapes

• some particles are softer than

others

• some shine while others appear dull

What can the students conclude about

their sample?

F It is an element.

G It is a compound.

H It is a homogeneous mixture.

J It is a heterogeneous mixture.

a basic solution is an aqueous solution containing more oh-ions than h+ions. in other words, it is an aqueous solution with a ph greater than 7. basic solutions contain ions, conduct electricity, turn red litmus paper blue, and feel slippery to the touch.

explanation:

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.
