Explanation:
Answer:
a) 2
b) 2
c) 5
d) 5
e) 5
Explanation:
a) There is 1 Ag atom and 1 Cl atom. <em>When there's no subscript number next to an element, it means there is only one.</em>
b) There is 1 Ca atom and 1 O atom.
c) There are 3 Mg atoms (there's a subscript 3 next to Mg) and 2 N atoms.
d) There are 2 Al atoms and 3 O atoms.
e) There are 2 Sc atoms and 3 S atoms.
Q or the Reaction Quotient is the interaction between the reactants and products in a given chemical reaction. The value of Q should be compared to the value of K (which is the value of the reaction at equilibrium) in order to determine which way the reaction should move to achieve equilibrium.If Q is already equal to K, then this indicates that the reaction is in equilibrium. If Q>K, then the reactants are converted to products; If Q<K, then the products are converted to reactants. Either way, the reaction proceeds to move towards equilibrium after some time.
Answer:
D) is the answer please thanks
(a)The change in Gibbs free energy for the reaction has been 2.6 kJ/mol.
(b) The change in Gibbs free energy for the reaction has been -49.3 kJ/mol.
(c) The change in Gibbs free energy for the reaction has been 91.38 kJ/mol.
