Zn + Cu²⁺ → Zn²⁺ + Cu
Explanation:
The overall equation of this redox reaction is combination of the two half equations. The similar species on both sides are cancelled out leaving a net overall reaction:
Zn → Zn²⁺ + 2e⁻ oxidation step
Cu²⁺ + 2e⁻ → Cu reduction step
Combining both equations:
Zn + Cu²⁺ + 2e⁻ → Zn²⁺ + 2e⁻ + Cu
since the common specie on both sides is 2e⁻, they cancel out to give an overall reaction:
Zn + Cu²⁺ → Zn²⁺ + Cu

The chemical formula for zinc is Zn, and HCl for hydrogen chloride. The complete balanced equation for these reactants would be:
Zn + 2 HCl → ZnCl₂ + H₂
The stoichiometric coefficient 2 for HCl is essential to obey the Law of Conservation of Mass. The elements before and after the reaction must be equal in amounts.
If two forces from opposite directions are applied to a malleable object like aluminum, it will change it shape.
<h3>WHAT IS MALLEABILITY?</h3>
A malleable object is an object that can be beaten into sheet when hit. Malleable objects are often metals that can endure high tensile stress.
Aluminum is an example of metal that posseses the characteristics of malleability.
This means that if two forces from opposite directions are applied to a malleable object like aluminum, it will change it shape.

Answer:
The new pressure is 1,67atm
Explanation:
In this case, having constant temperature we apply Boyle Mariotte's Law, where the volume varies inversely proportional to the pressure: P1 xV1 = P2xV2. We pass the pressure unit from Torr to atm: 760 Torr = 1atm
P1 xV1 = P2xV2 --> P2=P1 xV1/V2
P2= 1 atm x 5,00L/3, 00L=1, 67 atm
