Surface tension :<span>the tension of the surface film of a liquid caused by the attraction of the particles in the surface layer by the bulk of the liquid, which tends to minimize surface area.</span>
All of the acid molecules in beaker 1 dissociate fully and exist as and ions. As a result, beaker 1 represents a strong acid solution. The majority of the molecules in beaker 2 are undissociated.
Heat energy can be calculated by using the specific heat of a substance multiplying it to the mass of the sample and the change in temperature. It is expressed as:
<span>
Energy = mCΔT
</span><span>Energy = 132 (0.385) (45 - 32.2)
</span><span>Energy = 650.50 J</span>
Answer:
the answer is true
Explanation:
as sound travels through the air it creates a disturbance in the particles of the medium
Answer:
4.88 g / cm³
Explanation:
Density of a substance is given by the mass of the substance divided by the volume of the substance .
Hence , d = m / V
V = volume
m = mass ,
d = density ,
From the question ,
The mass of the metal = 24.54 g
The volume of the metal = 5.02 mL
Hence , by using the above formula ,and putting the corresponding values , the density is calculated as -
d = m / V
d = 24.54 g / 5.02 mL
d = 4.88 g /mL
The unit 1mL = 1 cm³
Hence ,
d = 4.88 g / cm³
