Answer:

The difference between an element and a compound is that an element is a substance made of same type of atoms, whereas a compound is made of different elements in definite proportions. Examples of elements include iron, copper, hydrogen and oxygen. Examples of compounds include water (H2O) and salt (Sodium Chloride - NaCl)

Explanation:

Further Differences:

Defintion:

Compound - A compound contains atoms of different elements chemically combined together in a fixed ratio.

Element - An element is a pure chemical substance made of same type of atom.

Representation:

Compound - A compound is represented using its chemical formula that represents the symbols of its constituent elements and the number of atoms of each element in one molecule of the compound.

Element - An element is represented using symbols.

Composition:

Compound - Compounds contain different elements in a fixed ratio arranged in a defined manner through chemical bonds. They contain only one type of molecule. Elements that compose the compound are chemically combined.

Element - Elements contain only one type of atom. Each atom has the same atomic number i.e., the same number of protons in their nucleus.

What is the average of the two weights of a nickel and dime. Dime is 2.26g and nickel is 4.97g?

ANTONII [103]

Dime=2.26g
Nickel=4.97g

$\\ \rm\Rrightarrow Avg\:Weight=\dfrac{Sum\:of\:Weights}{No\:of\:weights}$

$\\ \rm\Rrightarrow Avg\:weight=\dfrac{2.26+4.96}{2}$

$\\ \rm\Rrightarrow Avg\;weight=\dfrac{7.23}{2}$

$\\ \rm\Rrightarrow Avg\:Weight=3.6g$

It 32g of potassium nitrate can be dissolved in 1cm3 of water at 20oC before a saturated solution is obtained, how much potassiu

Dmitry_Shevchenko [17]

Answer:

160 gm

Explanation:

Five times as much water means you can dissolve 5 times as much potassium nitrate 5 x 32 = 160 gm <u> <===== this seems unlikely though as I doubt 32 g of potassium nitrate will dissolve in only 1 cm^3 of water 1 cm^3 of water is only 1 gm of water </u>
