The electrolyte magnesium chloride (MgCl2) will break up into how many individual particles in water (what is the i value)?

1 answer:

3 0

Answer:

Solid magnesium chloride is a non-conductor of electricity because the ions aren't free to move. However, it undergoes electrolysis when the ions become free on melting. Magnesium chloride dissolves in water to give a faintly acidic solution (pH = or 6).

Answer: 292.54g of Ag

Explanation:

Cu + 2AgNO3 →Cu(NO3)2 + 2 Ag

mass conc. Of Ag = n x molar Mass

Mass conc. Of Ag = 2 x 108 = 216g

From the equation,

63.5g of Cu produced 216g of Ag

Therefore, 86g of Cu will produce Xg of Ag. i.e

Xg of Ag = (86 x 216)/63.5 = 292.54g

Draw a chair conformation for cis-1-bromo-2,4-dimethylcyclohexane showing equatorial and axial positions at the carbon atoms bea

Ahat [919]

Answer:

See attachment.

Explanation:

Mono-substituted cyclohexanes are more stable with their substituents in an equatorial position. However, with poly-substituted cyclohexanes, the situation is more complex since the steric effects of all substituents have to be taken into account. In this case, you can see that <u>the interconversion is shifted towards the conformation in the bottom because there is less tension between the substituents</u>.

Gold has a density of about 20g/mL. If I measured out 2mL of gold, I would expect it to have a mass of about ___ grams.

yan [13]

The answer is 40 grams. If gold is 20 grams per mL and you have 2 mLs, you get 40 grams of gold. Just add 20 + 20 or multiply 2 x 20 to get 40.
