Answer:
Explanation:
The chemical equation for the reaction is :
The standard enthalpy of formation of the above equation is as follows:
= -1274.4 kJ/mol
= -277.7 kJ/mol
= -393.5 kJ/mol
where ;
= stochiometric coefficients of products
stochiometric coefficients of reactants
= formation standard enthalpy of products
= formation standard enthalpy of reactants
For ;
The standard enthalpy of formation of of the reactant and the products are :
The is as follows:
(to kJ/K)
Given that;
at T = 25°C = ( 25 + 273) K = 298 K
As is negative; the reaction is spontaneous
= negative
= positive; Therefore , the reaction is spontaneous at all temperature , We can then say that the spontaneity of this reaction is dependent on temperature.
Le Chatelier's Principle says that when something disrupts the equilibrium, the system adjusts to minimize the effect of that disturbance. If 0.1 M HCl solution is added, this dissociates into H+ and Cl- ions, so there will be more Cl- ions in the system. This causes the reaction to go in the reverse direction (equilibrium shifts to the left) to reduce the amount of Cl-.
Since this also consumes Ag+ ions, the concentration of Ag+ (aq) will decrease.
The answer is the second choice.
The Bohr model used to be used but it signifies that electrons stay stationary. The current model uses electron clouds in order to predict the location of an electron within an atom.
Additionally, we can predict the location of an electron, but we cannot exactly pinpoint it. So, the current atomic model cannot have a clear and exact placement for every electron around the nucleus of an atom. It also cannot have a clear and distinct border surrounding the nucleus of an atom where electrons are located.
Therefore, the current atomic model has a predicted area surrounding the nucleus where the electron could be located.
Answer:
Plastic is an insulator
Explanation:
This enables you to touch it without burning yourself because it does not conduct heat easily.
Answer:
34.23 grams H2O.
Explanation:
1 Mole of HCl produces 1 mole of water
So 1.9 moles producers 1.9 moles of water
= (2*1.008 + 16) * 1.9
= 18.016 * 1.9
= 34.23 grams H2O.
