Answer:
The answer to your question is: HCl = 58.44 g
Explanation:
To solve this problem, we must remember the law of conservation of mass that says that, matter cannot be created or destroyed, only changes its form.
That means that, the mass of the reactants must be equal to the mass of the products.
Process
Sodium (Na) + Chlorine (Cl) ⇒ Sodium chloride (HCl)
22.99 g 35.45 g x
22.99 + 35.45 = HCl
HCl = 58.44 g
Answer : The enthalpy of the reaction is, -2552 kJ/mole
Explanation :
According to Hess’s law of constant heat summation, the heat absorbed or evolved in a given chemical equation is the same whether the process occurs in one step or several steps.
According to this law, the chemical equation can be treated as ordinary algebraic expression and can be added or subtracted to yield the required equation. That means the enthalpy change of the overall reaction is the sum of the enthalpy changes of the intermediate reactions.
The given enthalpy of reaction is,
The intermediate balanced chemical reactions are:
(1) 
(2) 
(3) 
(4) 
Now we have to revere the reactions 1 and multiple by 2, revere the reactions 3, 4 and multiple by 2 and multiply the reaction 2 by 2 and then adding all the equations, we get :
(when we are reversing the reaction then the sign of the enthalpy change will be change.)
The expression for enthalpy of the reaction will be,
Therefore, the enthalpy of the reaction is, -2552 kJ/mole
The answer is (1). The hydrocarbon is a compound consists only with carbon and hydrogen. Ethane is C2H6. Chloroethane is C2H5Cl. Ethanol is CH3OH. Ethanoic acid is CH3COOH.
The ice caps, lakes, rivers, and other bodies of water can be found all around the globe
The given complex Ion is,
[Co(CN)₃]³⁻
In complex compounds the Positive part is named first, followed by name of Negative part. In given case there is no Positive part. So, we will name the Negative part.
In Sphere the Ligands are named first. In this case there are 6 CN⁻ ligands. As CN⁻ (cyanide) contains a negative charge so the -ide is replaced by -o. i.e. Cyanide → Cyano. Also, Hexa is placed before Cyano as there are 6 CN⁻ Ligands.
So,
Hexacyano
After that Chromium metal is named. As there is a negative charge on the sphere, so the -ium in Chromium is replaced by -ate.
i.e. Chromium → Chromate. And the oxidation state of Cr is written in Roman. Hence,the name is as,
Hexacyanochromate (III) Ion
