Answer: The molar enthalpy change is 73.04 kJ/mol
Explanation:
moles of HCl= 
As NaOH is in excess 0.0415 moles of HCl reacts with 0.0415 moles of NaOH.
volume of water = 100.0 ml + 50.0 ml = 150.0 ml
density of water = 1.0 g/ml
mass of water = 
q = heat released
m = mass = 150.0 g
c = specific heat = 
= change in temperature = 
Thus 0.0415 mol of HCl produces heat = 3031.3 J
1 mol of HCL produces heat = 
Thus molar enthalpy change is 73.04 kJ/mol
Answer:
A molecule is stable when there is no energetically-accessible mechanism available that allows it to reacts and form a more stable molecule or molecules whiles Are configuration of unknown atomic nuclei and electrons discovered by Reed Richard
White blood cells work in two ways; they can ingest or engulf pathogens and destroy them by digesting them. White blood cells can also produce antibodies to destroy particular pathogens by clumping them together and destroying them. They also produce antitoxins that counteract the toxins released by pathogens.
Answer:
4HCl(g) + O₂(g) → 2Cl₂(g) + 2H₂O(g)
Explanation:
In order to find the equation we should state:
The reactants → Hydrogen chloride (HCl) and oxygen (O₂)
The products → Chlorine gas (Cl₂) and water gas (H₂O)
The balanced equation is:
4HCl + O₂ → 2Cl₂ + 2H₂O
It is a redox reaction, where the oxygen reduces to make water, and the chloride is oxidized to produce elemental chlorine.
From 5 L to moles, just divide 5 by 22.4. I got 0.22 moles of H2.
From 5 moles to liters, just multiply 5 by 22.4. I got 112 L of H2.
