The balanced chemical reaction would be written as follows:
CuCl2 + 2NaNO3 = Cu(NO3)2 + 2NaCl
This is an example of a double displacement type of reaction where the ions of the reactants displaces each other forming two new substances. Hope this answers the question.
Answer:
Explanation:
The pressure is constant, so we can use Charles' Law to calculate the volume.
Data:
V₁ = 22.4 L; T₁ = 273.15 K
V₂ = ?; T₂ = 136.58 K
Calculations:
An ideal gas is cooled at constant pressure, option A. A. ΔH is less than (more negative) Δ E of the system.
∆H is the exchange in enthalpy from reactants to products A ΔHº charge represents an addition of electricity from the reaction and from the surroundings, resulting in an endothermic response. A horrible cost for ΔHº represents the removal of power from the reaction and into the surroundings and so the reaction is exothermic.
The enthalpy of a system can not be measured right away because of the fact the inner energy consists of additives that are unknown, now not effects available, or aren't of interest in thermodynamics.
Hence, the answer is option A.

The organic meaning in chemistry is natural containing carbon.
<u><em> Explanation</em></u>
The natural matter or compounds which contain carbon are referred to as organic compounds.
Example of organic compound is protein which are made up of amino acid.
Amino acid is made up of carbon, hydrogen oxygen and nitrogen atoms.
Answer:
ΔGº = --29 kJ
Explanation:
The equation to use is ΔGº = -nFEºcell
where n is the number of mole of electrons exchanged in the redox equation
F is Faraday´s constant 96485 C/mole
Eº cell potential
Ni²⁺(aq) + 2e⁻ ⇒ Ni (s) Eºred = -0.25 V
Cd(s) ⇒ Cd²⁺ + 2e⁻ Eºox = +0.40 V
Eºcell = 0.40 V -0.25 V = 0.15 V
ΔGº = - 2 mole x 96485 C/mol x 0.15 V = -2.9 x 10⁴J = -29 kJ
(remember 1 Coulomb x 1 Volt = 1 Joule)
