A way to classify an acid as being weak is to determine how strongly the substance conducts electricity. If the acid or base conducts electricity strongly, it is a strong acid or base. If the acid or base conducts electricity weakly, it is a weak acid or base.

Answer:

3 scenarios:  

1. acetic acid, organic acid that comes from vinager

2. citric acid, that is present in some fruits

3. phosphoric acid , present in sodas

Explanation:

A weak acid is the one that partially transferres its proton (H+) to a water molecule ( partial dissociation), and usually a part of the original acid (HA) remains after the process of dissociation; that is why, a dissociation reaction of a weak acid is represented with an arrow of both ways.

HA ⇌ H^{+} +A^{-}

As we can see, the acetic acid, citric acid and phosphoric acid are great examples of weak acid. Their pH is higher thanks to its low dissociation, and they can even be eaten in low concentrations.

aluminum bronze contains 92.0% of copper and 8.0% aluminum. what maximum mass of aluminum bronze can be prepared from 73.5g of c
slega [8]
The answer is 79.9 g.

Copper takes 92.0% of aluminum bronze and it is a limiting factor. We have aluminum in excess, so we need to make a proportion.
If 73.5 g of copper are 92.0%, how many g of aluminum bronze will be 100%:
73.5 g : 92.0% = x : 100%.
x = 73.5 g : 100% * 92.0%
x = 79.9 g

Therefore, from 73.5 g of copper and 6.4 g of aluminum (since 79.9 g - 73.5 g = 6.4 g), maximum 79.9 g of aluminum bronze can be prepared.

Give the formulas for the following
zubka84 [21]

Li2O

Fe(NO3)3

Al2O3

CuCl2

ZnSO4

All you have to do here is make sure your charges are balanced when you write the compound. For example, Iron (III) has a +3 charge, and nitrate has a -1 charge. You need 3 nitrates to match that charge, hence Fe(NO3)3.
