For neutralization of acid by a base (or vice versa), the equation should be used.
M₁V₁ = M₂V₂
where M's are the molarity and the Vs are the volume. Substituting the known values,
(0.150M)(25) = M₂(15 mL)
The value of M₂ from the equation is equal to 0.25M. Thus, the concentration of the acid is 0.25M.

Step 1: Translate the starting chemicals into formulas:Iron metal, in the presence of oxygen,----->Step 2: Predict the produc

Natalija [7]

Answer:

Explanation:

Here, we want to write the chemical reaction

step 1:

we start by writing the reaction between iron and oxygen

We have this as:

$\text{ Fe + O}_2$

step 2:

Now, we want to predict the product as follows:

$\text{ Fe + O}_2\text{ }\rightarrow Fe_2O_3$

step 3:

We proceed to balance the chemical reaction as follows by ensuring that the number of elements moles on the reactant side is equal to the number of moles of the elements on the products side as follows:

$\text{ 4Fe + 3O}_2\text{ }\rightarrow2Fe_2O_3$
