D -a substance made of more than one type of atom
Llana [10]3 years ago
3 0

Answer:

b. a substance made of only one type of atom

Explanation:

Elements are what you find on the periodic table of elements.

Take oxygen, for example. You can have one or multiple atoms, but if they are all oxygen atoms it's an element.

"a" is incorrect because water is not an element, it is a compound.

"c" is incorrect because such a thing (as far as we know) does not exist, unless we are talking about subatomic particles like protons, neutrons, and electrons that make up an atom.

"d" is incorrect because it describes a compound.

Solar radiation provides more heat and cleaner than near the pools on Earth the greatest amount of heat is moved away from the e
Rashid [163]

Answer:

Ocean Currents

Explanation:

The correct answer is Ocean currents.

When the earth receives solar radiation, a large fraction of this incident radiation is usually absorbed by the oceans and the seas, which become warm. Usually, equitorial regions are the ones that have this phenomenon. Now, when ocean currents are flowing from the equator, they usually carry this warm water with them thereby moving the greatest amount of heat from the equator on its way out.

For example, In the Pacific Ocean, there is a current known as Alaska Current that carries warm water in the northward direction thereby making Anchorage which is Alaska's largest city to have a much mild weather than the inland areas with the same latitude.

Fill in the blanks: Electrons are ___ in an ionic bond, whereas they are___ in a polar covalent bond, and ___ in a nonpolar cova
NNADVOKAT [17]

Answer:

The correct answer is "transferred; unequally shared; equally shared".

Explanation:

Ionic bonding occurs when a positively charged atom (cation) interacts with a negatively charged atom (anion). In ionic bonding, the cation transfers its electron to the anion. In polar covalent bonding, electrons are unequally shared. This means that the electrons spend more time in an atom than the other, which gives partial positive and negative charges to the atoms. On the other hand in nonpolar covalent bonding, the electrons are equally shared and no charges are created.
