Answer:
Separated
Explanation:
Stan does not feel he identifies closely with the group. He feels the other members are close knit with each other but he is not part of the group.
For Stan, it would be an illusion to say he has a close relationship with the members of the group
This infers that Stan has a separated self-schema with respect to the group.
The mass of the sample is 84.3 g
<u>Explanation:</u>
We have the formula to find the mass
Q = mCΔT
where
Q denotes the energy absorbed or released
m denotes the mass of the sample
C denotes the Specific heat of sample
Δ
T denotes the
Temperature change
Q = mCΔT
Rewrite the equation as,
m
=
Q/
C
Δ
T
m=24000 J/4.186 J/g°C×
( 69.5 °C-0°C)
m=82.42
m=84.3 (based on the options)
The mass of the sample is 84.3 g

Answer: Payback time = 0.0075
Explanation: Since payback time is calculated as:
payback time = 
First determine the installation cost:
100 mm thick insulation covers 8.3 m². Then 300 mm covers 24.9 m².
To cover 8.3m² costs £20. Then, the cost to cover 24.9 m² is:
cost = 
cost = £60
The cost of putting the insulation is £120, so the total cost is:
total cost = £60 + £120
total cost = £180
Savings per year per 100 mm thick is £80. For 300 mm, the value of annual savings is:
savings = 
savings = 240
payback time =
payback time = 
payback time = 0.75
Answer:1)1.99 M
Explanation:
Molarity is given as = moles solute/Liter solution
The solute which is LiOH is already given in moles as 1.495 moles
Given that solution is 750 mL, we convert to liters.
Liters of the solution= mL of the solution x (1 L/1000 mL)
750 mL x (1 L/1000 mL)
0.75 L
Molarity = moles solute/Liter solution
Molarity = 1.495 moles of LiOH/0.75 L of solution
Molarity = 1.99M
The molarity of this solution is 1.99M (moles per liter).
