The Arrhenius definition of acid-base reactions, which was devised by Svante Arrhenius, is a development of the hydrogen theory of acids. ... An Arrhenius base is a substance that dissociates in water to form hydroxide (OH -) ions. In other words, a base increases the concentration of OH - ions in an aqueous solution.
To answer this question, you need to know the aluminum acetate weight and formula. Molecular weight of aluminum acetate is 204.11g/mol, so the concentration should be: (25.20/204.11 )/(0.185l) = 0.1234 mol/0.185l= 0.6673 M<span>
</span>The aluminum acetate Al(C2H3O2)3 which mean for one aluminum acetate there will be 3 acetate ion. The concentration of acetate should be: 0.6673 M= 2M

Given
4 moles of Carbon dioxide.
Required
Carbon dioxide molecules
Carbon atoms
Oxygen atoms?
Solution
1 moles = 6.02 x 10²³ particles(molecules, atoms, ions)
1. Carbon dioxide molecules :
= 4 moles x 6.02 x 10²³
= 2.408 x 10²⁴ molecules
2. The number of Carbon atoms
In CO₂, there is 1 atom C, so the number of atoms :
= 1 x 2.408 x 10²⁴
= 2.408 x 10²⁴ atoms
3. The number of Oxygen atoms :
In CO₂, there is 2 atom O, so the number of atoms :
= 2 x 2.408 x 10²⁴
= 4.816 x 10²⁴ atoms
<u>Answer:</u> The equation is written below.
<u>Explanation:</u>
For the formation of nitrogen dioxide, the reactants used are nitrogen monoxide and oxygen gas.
The balanced chemical equation for the above reaction is given as:
By Stoichiometry of the reaction:
2 moles of nitrogen monoxide gas reacts with 1 mole of oxygen gas to produce 2 moles of nitrogen dioxide gas.
