The substage of sensorimotor development which this behavior reflect is an active experimentation.
<h3>What is an
active experimentation?</h3>
An active experimentation can be defined as a substage of sensorimotor development which is typically characterized by the use of theories in order to proffer solutions to problems or make decisions.
In this context, we can infer and logically deduce that the substage of sensorimotor development which Dennis' behavior reflect is known as an active experimentation.

<u>Complete Question:</u>
12 month old Dennis accidentally knocks his bowl off the table. The bowl spins on the floor before coming to a stop. Dennis's mom picks up the bowl and places it back on the table, so he knocks it down again to see if it will spin. Dennis knocks the bowl down each time his mother picks it up. What substage of sensorimotor development does this behavior reflect?
Answer:
When light passes through to samples of CuSO₄, the percent transmittance of light, %T, will be lower for Sample 1 compared to Sample 2.
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.
