Which word tells us the Minoans became very rich?
Which word tells us the Minoans became very rich (through trade)?
Where was half the US fleet destroyed in 1941?
Pearl Harbor
Why is Anne Frank's diary so valuable?
Because it tells us about the days that Jews spent during the war. It also tells us about their conditions and suffocation in the hideout.
Why did American soldiers use Agent Orange?
Predominantly deployed by US Airmen not US Soldiers (predominantly deployed by the USAF not the US Army). If an enemy can be seen, it can be shot (destroyed). AO destroyed forests (jungles) that concealed enemy movements and positions. This agent was replaced by Rome Plows operated by US Army engineers by 1970.
What do the early cave paintings tells us about early man?
It tells you what they hunt and other stuff they did.From Aldwinie
What does the name diphosphorus pentoxide tell us?
Tells us there are 2 phosphorus atoms and 5 oxygen atoms
What do valance electrons tell us about atoms?
they tell us if the substance is stable or not
What is avogandro's number?
Avogadro's number, approximately 6 x 1023, tells us how many atoms molecules are in a mol. For example, it tells us approximately how many hydrogen atoms in a gram of hydrogen, how many carbon atoms in 12 grams, etc.
What does a subscript tell us about an element in a compound?
In a molecular formula, the subscript tells us the number of atoms of the element that are present in one molecule of the compound. For instance,H2O tells us that there are two hydrogen and one oxygen atom per molecule of water. As for ionic compounds, it tells us the number of atoms present in one formula unit of the compound.
Is energy created when atoms are destroyed in a chemical reaction?
Atoms are never created or destroyed in a chemical reaction. There are the same number of each type of atom both before and after a chemical reaction. Atoms are never created of destroyed; the molecules are just re-arranged in their bonding with each other.
What tells the number of protons in the?
number of protons in the atoms tells us to what chemical element atoms belongs. in other words :different number of protons means different element. also protons together with neutrons make most of the atoms weight.
What 'SE' tells us how many atoms of each kind are there in a reaction?
The answer about SE is: symbol equation
What particle of an atoms tells us how to find the atomic number?
the number of protons in each atom
What does a balanced equation tells us?
A balanced equation has equal numbers of each type of atom on each side of the equation.Chemical equations usually do not come already balanced.It tells "Matter is neither created nor destroyed."Therefore, we must finish our chemical reaction with as many atoms of each element as when we started.
How does the conservation of matter tell us about atoms in chemical reactions?
Matter is neither created nor destroyed. Only change of bonds occur in atoms.
What tells an atoms mass?
This tells us that an atom of krypton has 36 protons in its nucleus. All you really need to find is something called the mass number.
What does infrared radiation tell us about molecules?
It tells us about how bonds stretch (or how atoms vibrate). This tells us about bond strengths and bond lengths, and can also be used to identify molecules (the infrared spectrum can be used as a "fingerprint" to identify what kinds of bonds a particular molecule has in it.
