Isomer is defined as compounds with the same formula but different arrangement of atoms in its molecule and they differ in their properties. The <span>representation that can be used to show differences between isomers is the use of structural formula. It shows the arrangement of each atoms. It cant be molecular formula and 3D drawing because it does not show the arrangement of the atoms.</span><span>

Answer:
yes
Explanation:
to identify an atom you need to know either it's atomic number or it's proton number
while the neutron is used to determine it's atomic mass
The given reaction is:
H2(g) + CO2(g) → H2O(g) + CO(g)
i.e.
H-H + O=C=O → H-O-H + C≡O
Reaction enthalpy (ΔH) is given as:
ΔH = ∑ΔH(Bonds broken) + ∑ΔH(Bonds formed)
= [1*ΔH(H-H) + 2*ΔH(C=O)] + [2*ΔH(O-H) + 1*ΔH(C≡O)]
=[+436 +2(799)] + [2(-463) +1(-1072)] = 36 kJ/mol
The enthalpy change for the given reaction is 36 kJ/mol
Answer:copper(II) sulfate, CuSO4> 2-pentanol, C5H11OH> methane, CH4>propane, C3H8.
Explanation:
Solubility depends on the ability of solute to interact effectively with a solvent. If water is the solvent, it interacts effectively with ionic substances. copper II sulphate is ionic and will be the most soluble in water, 2-pentanol, will interact effectively with water via hydrogen bonding. Between methane and propane, methane will interact better with water since it has a shorter alkyl chain than propane
Explanation:
The acetic acid is a polar compound. The polar molecules have a positive and negative extreme for this reason they are dipoles. The dipoles can attract other dipoles or ions. So, it can establish ion-dipole and dipole-dipole forces with the solute. In addition, acetic acid has a hydroxyl group that can interact with hydrogens or other very electronegative atoms (oxygen, nitrogen and fluor) forming hydrogen bridge junctions.
