Answer:
53.93 g Ag
Explanation:
3.011x1023 atoms Ag x <u> 1 mole Ag </u> x <u>107,8683 grams</u> =
6.022x
atoms 1 mole Ag
use the periodic table fo find Ag atomic mass and use Avogadro´s number
Answer:
Explanation:
Hello,
In this case, the dissociation of the given weak acid is:
Therefore, the law of mass action for it turns out:
![Ka=\frac{[H^+][A^-]}{[HA]}](https://tex.z-dn.net/?f=Ka%3D%5Cfrac%7B%5BH%5E%2B%5D%5BA%5E-%5D%7D%7B%5BHA%5D%7D)
That in terms of the change 
due to the reaction extent is:
Thus, by solving with the quadratic equation or solver, we obtain:
Which clearly matches with the hydrogen concentration in the solution, therefore, the pH is:

Convection
Explanation:
Heat is a form of thermal energy borne as result of thermal energy. It is observed as temperature differences between places.
There are different types of heat transfer:
- Conduction
- Convection
- Radiation
Conduction is a heat transfer which involves the actual movement of the collision of the molecules of the medium.
Convection is a heat transfer in fluids by their movement from areas of higher to places of lower heat.
Radiation is heat transfer using electromagnetism and does not involve molecules of the medium
The process of heat transfer from ground to the air touching it is convection. It involves particles of the air.

Answer:
Id say A. Competition, hope this helps
Explanation:
Hello!
Like many other elements in chemistry, when an atom's valence shell is filled the element becomes stable. Through the octet rule we know that when the very last valence shell becomes filled, the atom is stable and therefore it is highly unlikely for the element to form bonds with that of another.
I hope this helped!
