therefore:

So your answers are:

and the mole fraction is:
Answer:
an increase in temperature
Explanation:
The chemical reaction that is produced by modelage masks causes: an increase in temperature
Answer:
Number of moles of CoCl3 = 0.09 moles
Explanation:
Given data:
Mass of CoCl₃ = 12.1 g
Number of moles = ?
Solution:
First of all we will calculate the molar mass.
Molar mass of CoCl3 = 28.01 + (35.5×3)
Molar mass of CoCl3 = 28.01 + 106.5
Molar mass of CoCl3 = 134.51 g/mol
Number of moles of CoCl3 = mass / molar mass
Number of moles of CoCl3 = 12.1 g/134.51 g/mol
Number of moles of CoCl3 = 0.09 moles
Answer:
iv. The motion between A & B moves at a further distance than C & D's
v. The cyclist travels 800 meters
vi. It takes approx. 80 seconds
vii. The cyclist's speed is 10 meters per second (m/s)
viii. The cyclist's speed is also 10 meters per second (m/s)
vii. (2) The cyclist's average speed is 10 meters per second (m/s)
Explanation:
Speed is calculated using the formula distance divided by time (d/t)
vii (2) needs further explanation:
Though there is a moment of rest, the cyclist still travels the same speed throughout the entire trip. To check this answer however, you can total the distance and time the cyclist traveled and use speed formula to get 10 meters per second, again.
