Chemistry
1 answer:
Damm [24]3 years ago

1) False

An anion is a negative ion. When an atom loses valence electrons (i.e. loses negative charge) it becomes a positive ion (called cation, not anion).

2)  True

Non metals are at the right side of the periodic table. Those elements tipically have more than four valence electrons (except C which has 4 valence electrons). Then, by gaining some electrons (the number depends on the number of valence electrons that the non metal has),  they can complete the 8 valence electrons configuration of the nobles gases.

Given the balanced equation representing a reaction:
sleet_krkn [62]
4Al(s) + 3O2(g) --> 2Al2O3(s)    This is the balanced.
From the equation:

 4 moles of Al required 3 moles of O2 to produce 2 moles of Al2O3
 
3 moles of O2 reacted with 4 moles of Al to produce 2 moles of Al2O3
1 mole of O2 reacted with 4/3 moles of Al to produce 2/3 moles of Al2O3  (Divide by 3)
4.5 moles of O2 reacted with (4/3 *4.5) moles of Al to produce (2/3*4.5) moles of Al2O3

4.5 moles of O2 reacted with 6moles of Al to produce  3moles of Al2O3

(3) is the answer.  6 mol of Al.

what method can be used to separate parts of liquid mixture wwhen the entire mixture can pass through a filter
KIM [24]
The method that can be used to separate the mixture is DISTILLATION.
Distillation is a separating technique that is used to separate mixture of liquids which have boiling points that are far apart. The mixture will be heated, the liquid with the lowest boiling point will boil over and can be collected over a condenser, thus separating the two liquids.

Which would have a higher pH, a 0.1 M solution of a strong acid, or a weak acid? Why?
DerKrebs [107]

Answer:

0.1 M weak acid

Explanation:

The term pH simply means power of hydrogen which is basically a log (the exponent to base 10 of the concentration) of the concentration of the hydrogen ions.

Weak acids have a higher pH since their hydrogen concentration is lower than that of strong acids.
