The fact that the group of rats receiving reinforcement only after Day 10 performed better in solving the maze than those who have been reinforced from Day 1 showed that the Day 10 groups had already learned the maze during the first 9 days.
- Reinforcement strategy is used on psychology to strengthen an organisms behavior or perception towards a particular action.
- In Tolzman's study, the group who were reinforced after the 10th day solved the maze in a shorter time than those who gave received reinforcement before them.
- This could best be interpreted to mean that, the group of rats used to first 9 days to learn the maze, before starting their reinforcement on the 10th day.
Therefore, the Day 10 group had already learned about the maze quite well during the first 9 days, hence, they performed better than the day 1 group.

Answer:
a) 14.285
b) 8.956
Explanation:
Given :
The combustion of the ethanol is with air
Air is 21% oxygen
and, 79% nitrogen
thus, for 1 O₂ we have (79/21)N₂
thus,
the stochiometric equation for the combustion is as:
C₂H₅OH + 3[O₂ + (79/21)N₂] ⇒ 2CO₂ + 3H₂O + 3 × (79/21)N₂
Now,
the molecular weight of the fuel (C₂H₅OH) = (2× 12) + (5 × 1) + 16 + 1 = 46 g/mol
Molecular weight of the air = (2 × 16) + ((79/21) × 28) = 137.33 g/mol
a) air/fuel ratio on a molar basis
we have
air-fuel ratio = moles of air / moles of fuel
or
air-fuel ratio = [3 × 1 + 3 × (79/21)] / 1 = 14.285
b) air/fuel ratio on a mass basis = Mass of air / mass of fuel
or
air/fuel ratio on a mass basis = (number of moles of air × molar mass of air) / (number of moles of fuel × molar mass of fuel)
on substituting the values, we have
air/fuel ratio on a mass basis = (3 × 137.33) / (1 × 46) = 8.956
