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 a sample of gas is at 672 °C and 3.9 atm, what is the new temperature at 12.2 atm?
Snowcat [4.5K]
In order to calculate the final temperature of the gas, we may apply Charles's law, which states that the pressure and temperature of a fixed amount of gas at constant volume are directly proportional. Mathematically:
P/T = constant
(absolute temperature is used, so T = 672 + 273 = 945 K)
Thus,
3.9 / 945 = 12.2 / T
T = 2,956 K or 2,683 °C

Equations can be balanced by using the half-reaction method. Which step should be completed immediately after finding the oxidat
Dovator [93]
After finding the oxidation states of atoms, you identify the half reactions (option c).

The half reactions are given by the change of the oxidation states of the atoms.

For example if Cu is in the left side with oxidation state 0 and in the other side with oxidation state 2+, then there you have a half reaction (oxidation reaction). And if you have O with oxidation state 0 in the left side  and with oxidation state 2- in the right side, there you have other half reaction (reducing reaction).
