Options are as follow,
<span>A) Covalent bonds are formed by metals and nonmetals.
B) Covalent bonds are are typical of carbon compounds.
C) Covalent bonds are created by the attractions between oppositely charged ions.
D) Covalent bonds break apart when dissolved in water and allow for the conduction of electricity.
</span><span>Answer:
Covalent bonds are formed by mutual sharing of electrons between two atoms of having electronegativity difference less than 1.7. Among given options only option-B seems correct.
Explanation:
Carbon containing compounds are almost covalent in nature. Majority of organic compounds are made up of carbon, hydrogen, oxygen and nitrogen. And carbon makes covalent bonds with all these atoms.
Result:
</span>Option-B is correct.
Answer:
K = [H2] [CO] / [HCHO]
Explanation:
HCHO(g) ⇌ H2(g) + CO(g)
We can obtain the expression for the equilibrium constant for the above equation as follow:
Equilibrium constant, K for a given reaction is the ratio of the concentration of the product raised to their coefficient to the concentration of the reactant raised to their coefficient.
Thus, the equilibrium constant, K for the above equation can be written as follow:
K = [H2] [CO] / [HCHO]
