The table shows the types of elements that form two compounds. composition of compounds compound x compound y two nonmetals a metal and a nonmetal which of the following statements is true about how the bonding occurred to create the two compounds? electrons are shared in both the compounds. electrons are transferred in both the compounds. electrons are shared in compound x and transferred in compound y. electrons are transferred in compound x and shared in compound y.

Given:

Compound X = Non metal + Non-metal

Compound Y = Metal + Non-metal

To determine:

The nature of bonding in X and Y

Explanation:

Ionic bonds are chemical bonds that are formed by sharing of electrons between 2 atoms. One of the atoms has a greater tendency to lose electrons while the other has a tendency to accept electrons. Thus, ionic bonds are typically formed between a metal (which loses electrons) and a non-metal (gains electrons).

In contrast, a covalent bond is formed by mutual sharing of electrons and typically between non-metals.

Thus,

Compound X forms a covalent bond while Y forms an ionic bond

Ans: C) electrons are shared in X and transferred in Y

C ) Electrons are shared in compound X and transferred in compound Y.

Explanation:

Did the test and got it right

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7
