Answer:

Double displacement reaction

Explanation:

Chemical equation:

H₃PO₄ + NaBr      →    HBr + Na₃PO₄

Balanced chemical equation:

H₃PO₄ + 3NaBr      →    3HBr + Na₃PO₄

Step one:

H₃PO₄ + NaBr      →    HBr + Na₃PO₄

On left side of equation                  On right side pf equation

H = 3                                                   H = 1

P =  1                                                    P = 1

O = 4                                                    O = 4

Na = 1                                                   Na = 3

Br = 1                                                     Br = 1

Step 2:

H₃PO₄ + NaBr      →    3HBr + Na₃PO₄

On left side of equation                  On right side pf equation

H = 3                                                   H = 3

P =  1                                                    P = 1

O = 4                                                    O = 4

Na = 1                                                   Na = 3

Br = 1                                                     Br = 3

Step 3:

H₃PO₄ + 3NaBr      →    3HBr + Na₃PO₄

On left side of equation                  On right side pf equation

H = 3                                                   H = 3

P =  1                                                    P = 1

O = 4                                                    O = 4

Na = 3                                                   Na = 3

Br = 3                                                     Br = 3

Type of chemical reaction:

The given reaction is double displacement reaction on which cation and anion of both reactants are replace with each other.

Olegator [25]

Answer:

Left hand side:-

Carbon - 12

HYdrogen - 28

Oxygen - 38

Right hand side:-

Carbon - 12

Hydrogen - 28

Oxygen - 38

Since, the number of atoms each side are equal, the reaction is balanced.

Explanation:

The given reaction is:-

2C_6H_{14}_{(l)}+19O_2_{(g)}\rightarrow 12CO_2_{(g)}+14H_2O_{(g)}

Left hand side:-

Carbon - 12

HYdrogen - 28

Oxygen - 38

Right hand side:-

Carbon - 12

Hydrogen - 28

Oxygen - 38

<u>Since, the number of atoms each side are equal, the reaction is balanced.</u>

A 3.8-mol sample of KClO3 was decomposed according to the equation. How many moles of O2 are formed assuming 100% yield?
kari74 [83]

Answer:

5.7 moles of O2

Explanation:

We'll begin by writing the balanced decomposition equation for the reaction. This is illustrated below:

2KClO3 —> 2KCl + 3O2

From the balanced equation above,

2 moles of KClO3 decomposed to produce 3 moles of O2.

Next, we shall determine the number of mole of O2 produced by the reaction of 3.8 moles of KClO3.

Since 100% yield of O2 is obtained, it means that both the actual yield and theoretical yield of O2 are the same. Thus, we can obtain the number of mole of O2 produced as follow:

From the balanced equation above,

2 moles of KClO3 decomposed to produce 3 moles of O2.

Therefore, 3.8 moles of KClO3 will decompose to produce = (3.8 × 3)/2 = 5.7 moles of O2.

Thus, 5.7 moles of O2 were obtained from the reaction.
