The charge of the nucleus in an atom of oxygen is +8. The correct option is 3.
The charge is negative or positive or neutral charges present on the substance or molecule. The charges are produced by the gaining or losing of electrons.
The charges tell the tendency of the atom or molecule of gaining or losing of the atom.
Thus, the correct option is 3, +8.

Explanation :
As we know that the geometrical symmetry of the molecule and the polarity of the bonds both are equally important for determining the polarity of the molecule.
The molecule that has zero dipole moment that means it is a geometrical symmetric molecule and the molecule that has some dipole moment that means it is a geometrical asymmetric molecule.
As the molecule is symmetric, the dipole moment will be zero and the molecule will be non-polar.
As the molecule is asymmetric, the dipole moment will not be zero and the molecule will be polar.
Thus, we can say that the a symmetry molecule is non-polar in nature and an asymmetry molecule is a polar molecule.
All fossil fuels contains hydrocarbons in it. Amongst the given options hydrogen is the correct answer. Except that it contains carbon in it. Hydrocarbons are those class of compounds which contains hydrogen and carbon as element in it.
They are considered to be good fuels because they naturally bring out complete combustion as they contain hydrogen and carbon in its compound form.
Answer:
0.64 J/g-K
Explanation:
Solving this question relies on the relization that both blocks receive the same amount of energy but of course their temperature cannot rise by the same amount even if you had the same mass of both because they have different specific heat capacities.
amount of energy received by block 1 = amount of energy received by block 2
specific heat of block 1 * ΔT of block 1 = specific of block 2 * ΔT of block 2
C * 3 = 0.24 * 8
C = 0.64 J/g-K
