Answer:

When the no. of moles of reactant gases (a + b) = the no. of moles of product gases (c + d).

Explanation:

The relation between Kp and Kc is:

Kp = Kc(RT)∧Δn.

So, Kp = Kc, when Δn = zero.

Δn is the difference between the no. of gas molecules in the products side and that in the reactants side.

So, Δn = zero, when the no. of molecules of gases in the products side = the no. of molecules of gases in the reactants side which means (a + b) = (c + d).

How do you do this problem?

MariettaO [177]

Answer:

Explanation:

I can do it, but it may not be right. The atoms/ions and charges are all balanced, but I'm just not sure.

12Br2 + 12H20 ==> 4BrO3^- +20Br- + 24H+ You can divide this by 4

3Br2 + 3H20 ==> BrO3^- + 5Br^- + 6H+

Element/ion Left Right

Br 3*2 = 6 1 + 5 = 6

H 6 6H+

O 3 3

Charges 0 -1 - 5 + 6 = 0

The H+ represents an Acid. The problem is it says that the reaction takes place in an acid. It is so long ago, I don't remember if this includes being on the right.

Anyway it is balanced.

<h3>Explanation:</h3>

<u>Step 1: Define</u>

5.26 mol Fe₂(SO₄)₃

<u>Step 2: Identify Conversions</u>

Molar Mass of Fe - 55.85 g/mol

Molar Mass of S - 32.07 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of Fe₂(SO₄)₃ - 2(55.85) + 3(32.07) + 12(16.00) = 399.91 g/mol

<u>Step 3: Convert</u>

Set up: $\displaystyle 5.26 \ mol \ Fe_2(SO_4)_3(\frac{399.91 \ g \ Fe_2(SO_4)_3}{1 \ mol \ Fe_2(SO_4)_3})$
Multiply/Divide: $\displaystyle 2103.53 \ g \ Fe_2(SO_4)_3$

<u>Step 4: Check</u>

<em>Follow sig fig rules and round. We are given 3 sig figs.</em>

2103.53 g Fe₂(SO₄)₃ ≈ 2100 g Fe₂(SO₄)₃

Calcium reacts with a polyatomic ion to form a compound with the general formula Ca(X). What would be the most likely formula fo

BartSMP [9]

Answer:

B) K2X

Explanation:

In an uncharged compound, the total oxidation state must be zero. The oxidation state of the calcium is +2, thus we get the following formula, where x is the oxidation state of the polyatomic ion X:

$x + 2 = 0 \\ x = 0 - 2 \\ x = - 2$

Also, it is known that potassium has an oxidation state of +1. Since the new compound also has a total oxidation state equal to zero, we get the following equation, where k is the number of K atoms:

$k \times 1 + ( - 2) = 0 \\ k - 2 = 0 \\ k = - ( - 2) \\ k = 2$

That's how it is found that the compumd consists of 2 K+ ions and one X ion.

Complete and balance the following:(b) Sb₂O₃(s) + NaOH(aq) →

sammy [17]

Sodium tritioantimonate(III) and water are the products of the reaction between antimony(III) oxide and sodium hydroxide.

Sb2O3(s)+NaOH(aq)→Na3SbO3(aq)+H2O(l)

Balance the reaction from antimony, sodium, then hydrogen and oxygen.

Sb2O3(s)+6NaOH(aq)→2Na3SbO3(aq)+3H2O(l)

The equation is already balanced.

When each element in a chemical reaction has the same number of atoms and total charge on both the reactants and product sides of the equation, the reaction is said to be balanced. In other words, both sides of the reaction have an equal mass and charge of the components.

Because a chemical reaction is simply an arrangement of the atoms of the supplied elements, a chemical equation must be balanced. For the law of conservation of mass to be followed, the chemical equation must be balanced.
