Answer:
4.21
Explanation:
use Avogadro's number
6.023 x 10^23
multiply this by 7 because you want to find 7 moles :
6.023 x 10^23 x 7 = 4.21
Answer: The products formed in this Bronsted-Lowry reaction are
and
.
Explanation:
According to Bronsted-Lowry, acids are the species which donate hydrogen ions to another specie in a chemical reaction.
Bases are the species which accept a hydrogen ion upon chemical reaction.
For example, 
Here, the products formed in this Bronsted-Lowry reaction are
and
.
Thus, we can conclude that the products formed in this Bronsted-Lowry reaction are
and
.
Answer:
A the answer is A I'm sure
The corrects answer is 259 K
The kinetic energy and the physical state of water depend strongly on the temperature;
- Firstly, The kinetic energy of water on a hot stove is higher than that on the counter in the freezer; that the kinetic energy is directly proportional to the temperature according to the relation:
; where R is the universal gas constant, T is the temperature and NA is Avogadro number.
As the temperature increases, the speed of colliding molecules increases and the kinetic energy increases.
- Secondly, The physical state of water depends on the temperature; water has three states (gas, liquid and solid) depends on the temperature.
- If a glass of water is putt on the counter in the freezer, it will be converted to the solid state (ice).
- And, as if it is putt on a hot stove, it will be vapor (gaseous state).
