The balanced equation :

2HCl + Zn ⇒ ZnCl₂ + H₂

<h3>Further explanation</h3>

Given

Reaction(unbalanced)

HCl + Zn ⇒ ZnCl₂ + H₂

Required

Balanced equation

Solution

Give a cofficient(the most complex compound=1)

aHCl + bZn ⇒ ZnCl₂ + cH₂

Make an equation

Zn, left = b, right = 1⇒b=1

Cl, left = a, right = 2⇒a=2

H, left = a, right = 2c⇒2c=a⇒2c=2⇒c=1

The equation becomes :

<em>2HCl + Zn ⇒ ZnCl₂ + H₂</em>

If 6.96 mol of C 5 H 12 reacts with excess O 2 , how many moles of CO 2 will be produced by the following combustion reaction? C
kati45 [8]

Answer:

34.8 moles of CO₂ are produced

Explanation:

This is the reaction:

1C₅H₁₂ + 8O₂  →  6H₂O  +  5CO₂

Ratio is 1:5. We make a rule of three

1 mol of pentane can produce 5 moles of CO₂

Then, 6.96 moles of pentane may produce (6.96 .5) / 1 = 34.8 moles

Complete the charge balance equation for an aqueous solution of h2co3 that ionizes to hco−3 and co2−3.
Zielflug [23.3K]

The charge balance equation for an aqueous solution of H₂CO₃ that ionizes to HCO₃⁻ and CO₃⁻² is [HCO₃⁻] =  2[CO₃⁻²] + [H⁺] + [OH⁻]

<h3>What is Balanced Chemical Equation ?</h3>

The balanced chemical equation is the equation in which the number of atoms on the reactant side is equal to the number of atoms on the product side in an equation.

The equation for aqueous solution of H₂CO₃ is

H₂CO₃ → H₂O + CO₂

The charge balance equation is

[HCO₃⁻] =  2[CO₃⁻²] + [H⁺] + [OH⁻]

Thus from the above conclusion we can say that The charge balance equation for an aqueous solution of H₂CO₃ that ionizes to HCO₃⁻ and CO₃⁻² is [HCO₃⁻] =  2[CO₃⁻²] + [H⁺] + [OH⁻]

What is the pressure in a 24.0-LL cylinder filled with 32.7 gg of oxygen gas at a temperature of 319 KK? Express your answer to
Blizzard [7]

Answer:

The pressure in that cylinder = 1.12atm

Explanation:

We use general gas law to calculate it. General gas law is gotten by combining Boyle's law, Charles' law and Avogadro's law. Thus

P = nRT/V

Where n = number of moles

R = the gas constant

T is the Temperature, V is the volume and P is the pressure.

Given: T = 319K, V = 24L, R = 0.0821 L.atm/K.mol

The first step is to find n using

n = mass of O2/molar mass of O2

=32.7/32

=1.0219

Now, using P =nRT/V

P = 1.0219 ×0.0821×319÷24

Therefore P = 1.12atm
