Answer: cations

Explanation:

Metals are defined as the elements which loose electrons to attain stable electronic configuration. If an atom looses electrons, it leads to the formation of positive ions known as cations.

For Example: Sodium looses 1 electron to form $Na^+$ ions.

Non-metals are defined as the elements which gain electrons to attain stable electronic configuration. If an atom gains electrons, it leads to the formation of negative ions known as anions.

For Example: Fluorine gains 1 electron to form $F^-$ ions.

A stock solution has a concentration of 1.5 M SO2 and is diluted to a 0.54 M solution with a volume of 0.18 L. What was the volu

erastova [34]

The volume of the stock solution that has a concentration of 1.5 M SO2 and is diluted to a 0.54 M solution with a volume of 0.18 L is 0.065L.

<h3>How to calculate volume?</h3>

The concentration of a solution can be calculated using the following formula:

C1V1 = C2V2

Where;

C1 = initial concentration = 1.5M
C2 = final concentration = 0.54M
V1 = initial volume = ?
V2 = final volume = 0.18L

1.5 × V1 = 0.54 × 0.18

1.5V1 = 0.0972

V1 = 0.0972 ÷ 1.5

V1 = 0.065L

Therefore, the volume of the stock solution that has a concentration of 1.5 M SO2 and is diluted to a 0.54 M solution with a volume of 0.18 L is 0.065L.

2Al + 3H2SO4 -> Al2(SO4)3 + 3H2How many grams of aluminum sulfate would be formed if 250g H2SO4 completely reacted with alumi

bazaltina [42]

Answer:

290.82g

Explanation:

The equation for the reaction is given below:

2Al + 3H2SO4 -> Al2(SO4)3 + 3H2 now, let us obtain the masses of H2SO4 and Al2(SO4)3 from the balanced equation. This is illustrated below:

Molar Mass of H2SO4 = (2x1) + 32 + (16x4) = 2 + 32 +64 = 98g/mol

Mass of H2SO4 from the balanced equation = 3 x 98 = 294g
