The correct answer is B. All liquids are denser than the ball, and honey is denser than corn syrup and maple syrup.
Explanation:
Differences in density cause substances such as solids or liquids to float or sink. In general, the substance sinks if it is denser, or floats if it is less dense. In this context, honey is the substance with the most density because it is at the bottom of the container. Also, honey is followed in density by maple syrup, and then by corn syrup. Moreover, if the ping pong ball floats in the most superficial layer, it is because this is less dense than any of the liquids. According to this, it can be concluded honey is denser than the other liquids, and the liquids are denser than the ball (option B.)
Answer:
Heat, Q = 3035.073 J
Explanation:
It is given that,
Mass of water, m = 15.5 g
Initial temperature,
Final temperature,
The specific heat of water is, c = 4.184 J/ g°C
The heat removed or absorbed by water is given by formula as :
So, the heat of 3035.073 J is removed from 15.5 g of water.
Answer:
<h2>Density = 10.01 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula
<h3>
</h3>
From the question
mass of metal = 54.52 g
Volume of metal = new volume - original volume of water in the cylinder
That's
new volume = 28.85 mL
original volume of water = 23.44 mL
Volume of metal
= 28.85 - 23.44 = 5.41 mL
Next we convert the volume from mL to cm³
1 mL = 1 cm³
5.41 mL = 5.41 cm³
Substitute the values into the above formula and solve
That's
<h3>
</h3>
We have the final answer as
<h3>Density = 10.01 g/cm³</h3>
Hope this helps you

Answer:
Isotopes
Explanation:
An isotope are the atoms of an element with similar chemical identity and number of protons but different atomic masses. This means that isotopes of an element differ from one another by their number of NEUTRONS.
For example, the uranium element possesses isotopes as follows: Uranium-235 and uranium-238. This two isotopes have the same chemical identity and number of protons/atomic no., which is 92. However, the atomic masses (235 and 238) are different.
