<span>Ethene (C2H4) is an alkene which means this compound has a double bond between the carbons. The hybridization hence is sp2. In this hybridization, the 2s orbital mixes with only two of the three available 2p orbitals, forming a total of 3 sp2 orbitals with one p-orbital remaining.</span>
In chemistry, neutralization is a chemical reaction in which an acid and a base react quantitatively with each other, and where the final Ph of the solution is neutral (7).
In a reaction in water, neutralization results in there being no excess of hydrogen or hydroxide ions present in the solution.
Answer:

Explanation:
Hello,
In this case, we use the Boyle's law which allows us to understand the volume-pressure behavior as an inversely proportional relationship:

Thus, solving for the final volume, once the pressure changes, we obtain:

Answer:
K2CO3(aq) + H2O(l)
Explanation:
Balance the equation
2KOH(aq) + CO2(g) ------ K2CO3(aq) + H2O(l)
-5.
-5 * 2 = -10
-10 + 17 = 7
