Answer : The expression for reaction quotient will be :
![Q_c=\frac{[Zn^{2+}]}{[Ag^{+}]^2}](https://tex.z-dn.net/?f=Q_c%3D%5Cfrac%7B%5BZn%5E%7B2%2B%7D%5D%7D%7B%5BAg%5E%7B%2B%7D%5D%5E2%7D)
Explanation :
Reaction quotient (Qc) : It is defined as the measurement of the relative amounts of products and reactants present during a reaction at a particular time.
The given redox reaction is :

In this expression, only gaseous or aqueous states are includes and pure liquid or solid states are omitted.
The expression for reaction quotient will be :
![Q_c=\frac{[Zn^{2+}]}{[Ag^{+}]^2}](https://tex.z-dn.net/?f=Q_c%3D%5Cfrac%7B%5BZn%5E%7B2%2B%7D%5D%7D%7B%5BAg%5E%7B%2B%7D%5D%5E2%7D)
Answer:
Mixture.
Pizza is a mixture of a lot of things like dough, sauce, meat, veggies, cheese, etc.
Each of those things is a mixture of other things like proteins, starches, sugars, water, fiber, vitamins, minerals, etc.
The answer would be 425.599 because 1 ATM is 760 mmHg.
Answer:
Because both CaCl2 and CaBr2 both contain elements (Chlorine and Bromine) from the same group (group 7)
Explanation:
Elements are placed into different groups in the periodic table. Elements in the same group are those that have the same number of valence electrons in their outermost shell and as a result will behave similar chemically i.e. will react with other elements in the same manner.
Chlorine and Bromine are two elements belonging to group 7 of the periodic table. They are called HALOGENS and they have seven valence electrons in their outermost shell. Hence, when they form a compound with Calcium, a group two element, these compounds (CaCl2 and CaBr2) will possess similar properties because they have elements that are from the same group (halogen group).
