Answer:

The average of given values is 2.1221 ml

Explanation:

Given data:

Given measurements = 3.00 ml , 2.0 ml, 2.987 × 10⁻³ml , 3.4856 ml

Average value of given measurements = ?

Solution:

Formula:

Average value = sum of all measurement  / total number of measurements

2.987 × 10⁻³ml = 0.002987 ml

Now we will put the  values.

Average value = 3.00 ml + 2.0 ml + 0.002987 ml+ 3.4856 ml / 4

Average value = 8.488587 ml / 4

Average value =  2.1221 ml

The average of given values is 2.1221 ml

Qualitatively estimate the relative melting points for each of the solids, and rank them in decreasing order. Rank from highest
baherus [9]

Answer:

The order is

Quartz > Calcium > Ammonia > Chlorine

Explanation:

Among given compounds

Quartz is a covalent compound with extensive bondings and thus it will have highest melting point

Calcium is a metal so it will have strong metallic bonds thus will have high melting point, however less than quartz.

ammonia is a polar molecule with weak hydrogen bond as intermolecular interactions thus will have higher melting point than chlorine

chlorine is a non polar molecule with weak intermolecular london dispersion forces.

Draw the best lewis structure for h 2 ​ co 3 ​ and calculate the formal charge on carbon.
schepotkina [342]
The Lewis structure of Carbonic Acid (H₂CO₃) is given below. In structure it is shown that carbon has a double bond with one oxygen atom and two single bonds with hydroxyl groups.

Formal Charge;
                        Formal charge is caculated as,

Formal charge  =  # of valence e⁻ - [# of lone pair of e⁻ + 1/2 # of bonded e⁻]

Formal charge on Carbon;

Formal charge  =  4 - [ 0 + 8/2]

Formal charge  =  4 - [4]

Formal charge  =  Zero
