Explanation:
Removing B from the system
- Decreases the rate of the reaction. Backward reaction (formation of reactants) is favoured.
Crushing A into a powder
- Increases the rate of reaction. This is because of the increased surface area of A.
Warming the system
- Increases the rate of the reaction. Temperature is proportional to rate of reaction.
Adding more A to the system
- Increases the rate of reaction. Forward reaction (formation of products) is favoured.
Putting the system into an ice bath
- Decreases the rate of reaction. Temperature is proportional to rate of reaction.
Decreasing the pressure of the system
- Decreases the rate of the reaction.
Answer:
5.12x10^23 atoms
Explanation:
To find atoms, you need to use Avogadro's number. Here is the equation:
0.085 mol x 6.022x10^23 atoms = 5.12x10^22 atoms of titanium
Keep in mind that units need to cancel and make sure to double check those sig figs!
Atoms are (stable) if it has (valence) electrons in its outer most energy level.
The answer is A. Mom carefully bandaged my finger.
