This answer is C hope this helped
Explanation:
Elements need a total of eight electrons to gain stability and look like a noble gas. So, they sometimes need sharing of two, four or even six electrons to complete their octate. So, they form double and triple covalent bonds. One more the reason is the interaction between the p orbitals of the combining atoms. for example A double bond, as in ethene H2C=CH2, arises from one combination of the s orbitals and one combination of the p_y orbitals.
Answer:
11.0L of carbon dioxide is produced
Explanation:
Balanced equation: 
According to balanced equation, 1 mol of 
produces 1 mol of 
So, 0.489 mol of produces 0.489 mol of
Let's assume behaves ideally.
So, 
where P is pressure, V is volume , n is number of moles, R is gas constant and T is temperature in kelvin
Plug-in all the values in the above equation-
or, 
So, 11.0L of carbon dioxide is produced
Ionic compunds are able to conduct electricity when molten/in solution, but not when they are solid
