Choose the pair of substances that are most likely to form a homogeneous solution. a. nacl and hg b. lif and c6h14 c. nh3 and ch3oh d. c3h8 and c2h5oh e. br2 and pf3

Option (C) is the correct answer.

Explanation:

When a mixture contains two or more components that are evenly mixed together in a solvent is known as a homogeneous solution. And, whenever there occurs unequal distribution of components of the solvent and solute then the resulting solution is known as heterogeneous solution.

For example, when and are mixed together then there will occur hydrogen bonding between these two molecules.

But when NaCl and Hg are mixed then they will not combine with each other. Hence, the distribution will be uneven. So, the solution will not be homogeneous.

Similarly, LiF and , and , and will also lead to the formation of heterogeneous solution.

Thus, we can conclude that out of the given options and is the pair of substances that are most likely to form a homogeneous solution.

calculate how many grams of ammonia can be produced from 4.21 grams of

n2 + 3h2 = 2nh3

my answer:

25.0g n2 x (1 mol/ 28.0gn2) x (2 mol nh3/ 1 mol n2) x (17.0g nh3/ 1 molnh3) = 30.36g n2

25.0g h2 x (1 mol h2/ 2.00g h2) x (2 mol nh3/ 3 mol h2) x (17.0g nh3/ 1 mol nh3) = 141.67g h2

lr = n2
