In balancing chemical equations, all you need to do is make it so that you have the same number of each element on both sides of the eqtn (if I have 5C on the left, I have to have 5C on the right — an element can’t magically appear or disappear); that being said:

(2)C2H6 + 7O2 ➡️ 6H2O + 4CO2

(12)HClO4 + P4O10 ➡️ 4H3PO4 + (6)Cl2O7

2N2 + (5)O2 + 2H2O ➡️ 4HNO3

(3)CaCl2 + 2Na3PO4 ➡️ (1)Ca3(PO4)2 + 6NaCl

4FeS + 7O2 ➡️ 2Fe2O3 + 4SO2

Express the equilibrium constant for the combustion of propane in the balanced chemical equation c3h8(g)+5o2(g)???3co2(g)+4h2o(g

Karo-lina-s [1.5K]

According to the balanced equation:
C3H8(g) + 5O2(g) ↔ 3CO2(g) + 4 H2O (g)
aA + bB ↔ cC + dD

according to K formula when:
K = concentration of the products / concentration of the reactants

K = [C]^c[D]^d / [A]^a[B]^b
when [A],[B],[C]and[D] is the concentrations
and a,b,c and d is the no of moles
∴ K = [CO2]^3[H2O]^4 / [C3H8] [ O2]^5

Which of these chemical equations is correctly balanced?

vekshin1

The correct answer would be C. The third option shows a correct balanced chemical reaction. In order to say a reaction is balanced, it should be that the atoms of each element in the reactant side and the product side would be equal in number.

The balanced equation below represents the reaction between a 5.0 gram sample of zinc metal and 0.5 M of hydrochloric acid. The

Answer:

1) Increasing the concentration of HCl [HCl] will increase the reaction rate.

2) The potential energy diagram is shown in the attached image.

3) Because of it is an irreversible reaction that goes to the forward direction . The reaction takes place till HCl dissolves Zn completely.

Explanation:

Q1: State one change in reaction conditions, other than adding catalyst, that will increase the rate of the reaction.

The rate of the reaction, dissolving Zn in HCl, depends on the concentration of HCl.

Rate = k[HCl]².

Rate ∝ [HCl]².

The rate is directly proportional to the concentration of HCl raised to the power 2,

So, increasing the concentration of HCl [HCl] will increase the reaction rate.

Q2: Draw a potential energy diagram for this reaction.

Since the reaction releases energy that appears in the products side. So, the reaction is an exothermic reaction.

In an exothermic reaction, the energy of the reactants is higher than that of the products.

The potential energy diagram is shown in the attached image.

Q3: Explain why this reaction will not reach equilibrium.

Because of it is an irreversible reaction that goes to the forward direction . The reaction takes place till HCl dissolves Zn completely.
