The complete ionic equation:

Mg (s) + Zn(NO₃)₂ (aq) → Mg(NO₃)₂ (aq) + Zn (s)

Explanation:

We have the following net ionic equation:

Mg (s) + Zn²⁺ (aq) + 2 NO₃⁻ (aq) → Mg²⁺ (aq) + 2 NO₃⁻ (aq) + Zn (s)

The complete ionic equation will be:

Mg (s) + Zn(NO₃)₂ (aq) → Mg(NO₃)₂ (aq) + Zn (s)

The observation, in this case, is quantitative.

<h3>Quantitative observation</h3>

Quantitative observations are observations that can be recorded based on quantitative data. In other words, they are observations that can be assigned numerical values.

Quantitative observations are as opposed to qualitative observations because the former cannot be assigned numerical values. They can be ranked or qualified.

In this case, Danielle and Heather could assign numbers to the length, width, and height of the tank in order to calculate its volume.

Alexxx [7]
The normality that would be calculated will be to high because the change in volume will be greater than the actual change in volume. if the buret tip is not filled when reading the initial volume, the actual volume should be lesser with that reading. so if you will you the higher reading the change in volume or the volume you use in titration will be higher than the actual

For which of the following molecular formulas is the formula shown in parentheses the correct empirical formula? (a) C12H22O11 (
Elodia [21]

Answer:

C₁₂H₂₂O₁₁ (C₁₂H₂₂O₁₁ ).

Explanation:

The empirical formula is obtained when we divide the molecular formula with a whole number giving the simplest ratio of all the elements (in whole number).

a) C₁₂H₂₂O₁₁ :

There is no number with which we can divide the ratio further to get a simpler formula hence the molecular formula of the given compound is the empirical formula of the compound. Hence it is correct.

(C₁₂H₂₂O₁₁),

(b) C₈H₁₂O₄

The empirical formula can be obtained by dividing the formula with "4"

The empirical formula would be

(C₂H₃O)

(c) H₂O₂

The empirical formula would be (H₁O₁)
