Answer : The value of of the reaction is, -369.2 KJ
Explanation :
Formula used :
where,
= internal energy of the reaction = ?
= enthalpy of the reaction = -184.6 KJ/mole = -184600 J/mole
The balanced chemical reaction is,
when the moles of are 2 moles then the reaction will be,
From the given balanced chemical reaction we conclude that,
= change in the moles of the reaction = Moles of product - Moles of reactant = 4 - 4 = 0 mole
R = gas constant = 8.314 J/mole.K
T = temperature =
Now put all the given values in the above formula, we get:
Therefore, the value of of the reaction is, -369.2 KJ
Answer:
Density is a measure of mass per volume. The average density of an object equals its total mass divided by its total volume. An object made from a comparatively dense material (such as iron) will have less volume than an object of equal mass made from some less dense substance (such as water).
Explanat
Answer:
<u>One Electron</u> is transferred.
Explanation:
The reaction is as follow,
<span> AgNO</span>₃<span> + Na </span>→ <span>NaNO</span>₃<span> + Ag
Reduction of Ag;
AgNO</span>₃ + 1 e⁻ → Ag
Oxidation State +1 0
Oxidation of Na;
Na → Na⁺ + 1 e⁻
Oxidation State 0 +1
Result:
Therefore, Sodium transfers one electron to silver to reduce it.
To remember what the reactant is, it always comes before the yielding sign (arrow). The elements after the arrow are known as the 'products'.
So, with this information, let's look for our reactants.
Remember, the reactants are the elements BEFORE the yielding sign (arrow).
We have Hydrogen and Oxygen before the arrow.
Your answer is:
Hydrogen + Oxygen
