Answer:

<h3>HCL + NAOH ------ Nacl + h2o </h3>

  • here double displacement reaction takes place
  • Na displaces h from its salt solution
  • and form a bond with cl to make Nacl.
  • the remaining H and OH forms a bond as h+ and oh- gives H2o( water)
  • na+ and cl- as Nacl

In the reaction between copper and silver nitrate, 95.3 g of silver and 82.9g of copper nitrate are produced. How much of each r
Nastasia [14]

Reaction

2AgNO₃  +  Cu ⇒ Cu(NO₃)₂  +  2Ag

mol silver (Ag): 95.3 : 108 g/mol = 0.882

mol  copper nitrate (Cu(NO₃)₂): 82.9 : 187.5 g/mol = 0.441

mol Ag = 2 x mol Cu(NO₃)₂, so 0.441 being the mole basis of the reactants

mol Cu = 0.441

mass Cu = 0.441 x 63.5 g/mol = 28 g

mol AgNO₃ = 0.882

mass AgNO₃ = 0.882 x 170 g/mol = 149.94 g

equal volumes of equimolar aqueous solutions of sodium sulfite and hydroiodic acid are mixed. what net ionic equation describes
erica [24]

Na₂S₂O₃(aq) + 2HCl(aq) → 2NaCl(aq) + H₂O(l) + SO₂(g) + S(s). A light yellow precipitate develops as the process continues.

<h3>What does the chemistry term "equation" mean?</h3>

Reaction equation are symbolic depictions of chemical reactions where the reactants and products are stated in relation to the following chemical formulae.

<h3>Equation and response are what?</h3>

What is an equations and a chemical reaction? In a chemical change, bonds between molecules of the reagent are destroyed and new bonds between molecules of the product are established to create a new substance. A chemical formula is nothing more than a statement of fact that represents how reactants generate products.

A chemist fills a reaction vessel with 9.47 atm nitrogen monoxide (NO) gas, 2.61 atm chlorine (C12) gas, and 8.64 atm nitrosyl c
lys-0071 [83]

Answer:

\Delta _rG=2832.2J/mol

Explanation:

Hello,

In this case, the Gibbs free energy of that reaction is computed by computing the equilibrium constant as:

K=\frac{p_{NOCl}^2}{p_{NO}^2p_{Cl_2}} =\frac{8.64^2}{9.47^2*2.61}=0.319

Hence the Gibbs free energy:

\Delta _rG=-RTlog(K)=-8.314\frac{J}{mol*K}*298.15K*ln(0.319)\\\\\Delta _rG=2832.2J/mol

Best regards.
