Iron(II) is available to bond with chloride ion. How many of each type of ion will bond to form an ionic compound?

Evgesh-ka [11]

Answer:

D) 1 iron(II), 2 chloride

Explanation:

Iron II chloride is the compound; FeCl2. It is formed as follows, ionically;

Fe^2+(aq) + 2Cl^-(aq) -----> FeCl2

The formation of one mole of FeCl2 involves the reaction one mole of iron and two moles of chloride ions. This means that in FeCl2, the ratio of iron to chlorine is 1:2 as seen above.

Therefore there is one iron II ion and two chloride ions in each mole of iron II chloride, hence the answer.

Consider the reaction below 2SO2(g) + O2(g) ⇌ 2SO3(g) At 1000 K the equilibrium pressures of the three gases in one mixture were

Vsevolod [243]

Answer: $K_p$ for the reaction is 3.45

Explanation:

The balanced chemical reaction is:

$2SO_2(g)+O_2(g)\rightleftharpoons 2SO_3(g)$

At eqm. 0.562 atm 0.101 atm 0.332 atm

As we are given that:

The expression of $K_p$ for above equation follows:

$K_p=\frac{(p_{SO_3})^2}{(p_{SO_2})^2\times p_{O_2}}$

Putting values in above equation, we get:

$K_p=\frac{(0.332)^2}{(0.562)^2\times 0.101}=3.45$

The value of $K_p$ for the reaction is 3.45

Which is an example of a double

Ostrovityanka [42]

Answer:

NaCl + AgF → NaF + AgCl

Explanation:

A double replacement reaction is a type of chemical reaction that occurs when two reactants exchange cations or anions to yield two new products.

From all the reactions given ,

2Na + Cl₂ → 2NaCl is an example of combination reaction because two or more reactants (Na & Cl₂) react with each other to form a single product (NaCl)

H₂SO₃ → H₂O + SO₂ is an example of decomposition reaction because a single reactant (H₂SO₃) breaks down into two or more products (H₂O & SO₂).
2K + 2H₂O → 2KOH + H₂ is an example of displacement reaction because a highly reactive element (K) displaces a least reactive element (H) from its compound (H₂O).

NaCl + AgF → NaF + AgCl is an example of double replacement reaction because there's an exchange between Cations ( $Na^+$ & $Ag^{+}$ ) and Anions ( $Cl^-$ & $F^-$ ).
