Answer:
Option 3. Specific heat capacity of the liquid
Explanation:
Let's think, the states for the substance.
In -10, substance turns from solid state to liquid, so at 2°C , state is liquid.
We have to take from liquid state at 2°C to 155°C, which is the boiling point.
As the substance doesn't change its state, we only have to apply the specific heat capacity of the liquid.
1. specific heat capacity of the solid → This is used, when the substance is solid.
2. Heat of fusion → Only used when you turn from liquid to solid
4. Heat of vaporization → Used when the substance changes its state from liquid to gas
5. specific heat capacity of the gas → Used when the substance is a gas.
POH+pH=14
pH=14-pOH=14-3.53=10.47
pH=-log[H⁺]
[H⁺]=10^(-pH)
[H⁺]=10^(-10.47)=3.4*10(^-11)

Molecular mass:
Atomic masses:
N = 14g/mol H = 1g/mol S = 32g/mol O = 16g/mol Cl = 35.5g/mol
C = 12g/mol
NH₃ = 14 + 3(1) = 17g/mol
SO₂ = 32 + 2(16) = 64g/mol
Cl₂ = 2(35.5) = 71g/mol
N₂ = 14(2) = 28g/mol
CH₄ = 12 + (4 x 1) = 16g/mol
To solve this problem;
we need to derive an equation to find the molecular mass from the given densities on the table.
At STP;
Number of moles = eqn (i)
Also;
Number of moles = eqn (ii)
Now we can equate the two equations;
=
since density is known, we have to rewrite the relationship by making molar mass the subject of the expression:
Molar mass =
we know that;
Density =
Molar mass = density x 22.4
Now ;
Molar mass for 1.25g/L = 1.25 x 22.4 = 28g/mol; which is for N₂
Molar mass for 2.86g/L = 2.86 x 22.4 = 64.1g/mol; which is for SO₂
Molar mass for 0.714g/L = 0.714 x 22.4 = 16g/mol; which is for CH₄

A chemical formula shows the atoms and their respective quantity in a compound or molecule. The chemical formula CO2 reads as carbon, one atom, oxygen, two atoms. Another example is H2O (water).
Answer:
The tendency for water molecules to stick together causes it to causes spheres in space. ... Magnetic-like molecules on water's surface cause the surface to behave like an elastic skin. Each molecule is pulled with equal tension by its neighbors.J
