1-Bromo-1-methylcyclohexane has a molecular formula of C7H13Br
and an average mass of 177.082. Check the attached file for the structure of 1-Bromo-1-methylcyclohexane.
Answer:
C) 295 kJ/mol (average of the values given)
Explanation:
We can use Hess' Law to calculate the energy of formation of the C-Cl bond:
C-C → 2C ΔH = -347 kJ/mol
Cl-Cl → 2Cl ΔH = -243 kJ/mol
_______________________
C + Cl → C-Cl ΔH = (-347/2)+(-243/2)
ΔH = -295 kJ/mol
Answer:
Co²⁺ and PO₄³⁻
Explanation:
Strong electrolytes completely dissolve in water. Therefore, the ionic bonds between the cation and anion in Co₃(PO₄)₂ would break apart. The resulting ions would be Co²⁺ and PO₄³⁻. The phosphate (PO₄³⁻) would NOT further seperate because the phorphorus and oxygen bonds are covalent, not ionic. Phosphate ions are a type of polyatomic ion (ions which have covalent bonds).
That's the focus. Right above it on Earth's surface is the epicenter.
Hope this helps! Have a great day :)
