Answer:
The density of the metal sample is 2.70 
Explanation:
Density is a magnitude that allows you to measure the amount of mass in a given volume of a substance. Then, the expression for the calculation of density is the ratio between the mass of a body and the volume it occupies:
Density, according to the International System of Units, is usually expressed in kilograms per cubic meter (kg / m3) or gram per cubic centimeter (g / cm3). Although it can also be expressed in any other unit of mass by volume.
So, for the calculation of density you know that:
- mass of the sample= 10 grams
- volume of the sample = volume on the cylinder after immersion - volume on the cylinder before immersion= 38.7 mL - 35.0 ml = 3.7 mL
Then:
d=2.70
<u><em>The density of the metal sample is 2.70 </em></u><u><em></em></u>
The chemical reaction is:
<span>SO2Cl2 </span>⇔<span> SO2+ Cl2
This shows that the forward reaction the compound is decomposed to smaller compounds and the backward reaction the larger compound is produced. Adding more chlorine to the mixture when in equilibrium, will shift the equilibrium to the left forming the larger compound.</span>
Answer is both (b) and (d).
<em>Explanation;</em>
Equilibrium constant is written as a ratio between concentrations of products and reactants.
The equilibrium reaction is
A(g) ⇄ B(g)
Hence, the equilibrium constant can be expressed as
K = [B(g)] / [A(g)]
If there is more B, then A should be less. Hence, K value would be more than 1.
Hence, according to the given choices, K = 4000 and K = 1 x 10⁶ can be taken as correct answers.
Covalent compounds do not conduct electric current in a water solution well because they do not dissociate into ions.
