With all the coefficient set to 1, how can you tell that the equation is not balanced?
murzikaleks [220]

Answer:

Well for any equation if all the coefficients are set to 1, this might result in unequal numbers of atoms of the same element on both sides

Explanation:

For example:

A+B---->B_{2} + A_{2} (for this equation all the coefficient (the number before element) are 1 but you can clearly see it is not balanced because one side has 1 A atom and other side has 2 B atoms....therefore we need to balance em.

2A+2B-----> A_{2} + B_{2} Here both atoms are balanced.

A solution is made by dissolving 25.20 g of aluminum acetate in 185.0 mL of water. What is the concentration of acetate ions?
Andreas93 [3]
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
