Answer:
There are four types of partial reinforcement schedules: fixed ratio, variable ratio, fixed interval and variable interval schedules. Fixed ratio schedules occur when a response is reinforced only after a specific number of responses.

Answer:
The best testing strategy I have when it comes to multi choice is
if there are 4 answers ...2 of them you can easily eliminate with no problem. Then you have 2 more answers left and you find facts about each on and which one best relates to the question then boom. Oh and also always check for spelling and grammar in the answers because it will be wrong if its not correct.
The mass of the acetic acid is 1.512 g.
<h3 /><h3>What is Molarity?</h3>
molarity is the concentration of a substance in mol per dm³
From the question,
The number of moles contained in the 30 mL vinegar is
- n = (0.84×30)/1000
- n = 0.0252 mol.
the molar mass of vinegar is calculated below.
- m.m of (HC₂H₃O₂) = [1+(12×2)+(1×3)+(16×2)]
- m.m = (1+24+3+32]
- m.m = 60 g/mol.
To calculate the mass of acetic acid, we use the formula below.
- R.m = n×m.m............. Equation 1
Where
- R.m = mass of acetic acid.
Substitute these values into equation 1
- R.m = (0.0252×60)
- R.m = 1.512 g.
Hence, The mass of the acetic acid is 1.512 g.
