Answer:
The density of a potato is 
Explanation:
Given that,
A potato that is too large to fit into a graduated cylinder.
Let us consider the mass of potato is M and volume of entire potato is V'.
The volume of water is V.
We know that,
Density :
The density is equal to the mass divided by volume.
In mathematically,
Where, m = mass
V = volume
We need to calculate the volume of potato
Using formula for volume
Where, V' = volume of potato
V''=Volume of combine water and potato
V = volume of water
We need to determine the density of a potato
Using formula of density
Put the value into the formula
Hence, The density of a potato is
An atom is most stable when it has eight electrons in its outermost energy level.
Answer:
E) are electrically attracted to each other
Explanation:
Water molecule is polar because there is a difference in electronegativity values between hydrogen and oxygen. The hydrogen side of the molecule has a slight positive charge and the oxygen side is slightly negatively.
Positively and negatively charged ends cause water molecules to attract one another and for this reason water shows the properties mentioned in the question: cohesion, high specific heat, and high heat of vaporization.
In a closed system, heat should be conserved which means that the heat produced in the calorimeter is equal to the heat released by the combustion reaction. We calculate as follows:
Heat of the combustion reaction = mC(T2-T1)
= 1 (1.50) (41-21)
= 30 kJ
