Answer:

C.) The coefficient of iodine is 4, oxygen is 9, and the product is 2

Explanation:

An equation is balanced when there is an equal amount of each element on both sides of a reaction. If the amounts are unequal, you can modify the amount of molecules by adding coefficients.

The unbalanced reaction:

I₂ + O₂ -----> I₄O₉

Reactants: 2 iodine, 2 oxygen

Products: 4 iodine, 9 oxygen

The balanced equation:

4 I₂ + 9 O₂ -----> 2 I₄O₉

Reactants: 8 iodine, 18 oxygen

Products: 8 iodine, 18 oxygen

Remember, coefficients are the numbers placed in front of the molecular formulas. As such, the coefficient of iodine is 4, oxygen is 9, and the product is 2.

At 333 k, which of the pairs of gases below would have the most nearly identical rates of effusion?

rjkz [21]

E. co and n2Effusion is the process where gas escapes through a hole. Gases with a lower molecular mass effuse more speedy than gases with a higher molecular mass. Relative rates of effusion is related to the molecular mass.
a) M(N₂)/M(O₂) = 28/32 = 0,875
b) M(N₂O)/M(NO₂) = 44/46 = 0,956
c) M(CO)/M(CO₂) = 28/44 = 0,636
d) M(NO₂)/M(N₂O₂) = 44/58= 0,758
e) M(CO)/M(N₂) = 28/28 = 1, CO and N₂ have iexact molecular masses and will effuse at nearly identical rates.

What leads to the formation of an ionic bond with Hg2+?

statuscvo [17]

The attraction of an $SO_4^{2-}$ ion leads to the formation of an ionic bond with $Hg^{2+}$

<h3>What is an ionic bond?</h3>

Ionic bond, also called an electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound.

Since the question asking among all these options:

(a) The attraction of a noble gas

(b) The attraction of a $NH^{4+}$ ion

(d) The attraction of a $SO_4^{2-}$ ion

An ionic bond can be formed after two or more atoms lose or gain electrons to form an ion. Ionic bonds occur between metals, losing electrons, and nonmetals, gaining electrons.

Hence, option D is correct.
