Calcium will loose one electron. Fluorine will gain one electron. Lithium will loose one electron. Argon will not loose any because it already has a full valence level. Aluminium will loose 3 electrons.
The formula to find yield is
(Actual Yield)/(Theorectical Yield) x100
Just do the math.
85.22% x 113 = 96.2986
Convert it to 3 significant figures
Ans: 96.3g
Answer:
- Brush off any chemical dust around the balance after each use
- Alert your TA or instructor about any issues with the balance
Explanation:
The best practices while sharing a lab balance with other students includes alerting your TA or instructor about issues with the balance and Brushing off any chemical dust around the balance after each use. the practices will help to avert/reduce the work hazards associated with working with a balance.
Brushing off any chemical dust after each use will reduce the chemical hazards in the lab while Alerting your instructor about any issues with the balance helps to eliminate mechanical hazards that a faulty balance can pose
These responses are called "Reflex Action"
Hope this helps!
83.3 mL
Explanation:
M
= 3M
V = 50mL
M
= 1.80M
Unknown:
V = ?
Solution:
To solve this problem we must understand that the initial and final number of moles remains the same.
Number of moles = molarity x volume
Molarity x volume of initial solution = Molarity x volume of final solution
Therefore:
M x V = M x V
M is the molarity
V is the volume
i = initial state
f = final state
input the parameters;
3 x 50 = 1.8 x V
V = 83.3 mL
