What is the boiling point of a solution of 9.04 g of i2 in 75.5 g of benzene, assuming the i2 is nonvolatile?

374.2 K

Explanation:- Elevation in boiling point is:

= change in boiling point

= boiling point constant=

m = molality

Given: mass of solute = 9.04 g

Molar mass of solute = 254 g/mol

Weight of solvent (benzene)= 75.5 g= 0.0755 kg

The boiling point of the solution is .

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
