Write the balanced net ionic equation for the reaction that occurs in the following case: Fe(NO3)2 (aq) + KOH(aq)› Express your answer as a balanced net ionic equation. Identify all of the phases in your answer.

4- c, because all matter stays the same no matter what. it is still there. 5- b, because matter is known as mass. 6-c because, flammability is a chemical property. malleability is changing the shape of an object.

Answer:             1.0  × 10⁻⁵ msolution:                     as we know ph is given as,                                    ph  = -log [h⁺]and,                                    [h⁺]  =  10^-ph    (1)putting value of ph in eq. 1,                                    [h⁺]  =  10⁻⁵                                    [h⁺]  =  1.0  × 10⁻⁵ m

Descriptive investigations are mainly questions to uncover information. it does not have an hypothesis. it's mainly gathering information, it is not repeatable as you are just asking questions.
