The answer is Oxygen. The<span> elements that has the same lewis structure as sulfur is Oxygen. </span><span>This is due to the fact that although the two compounds have different electronic configurations, the two have the same arrangement of electrons in their outermost orbits. </span>
The answer to this is false
1.199 M is the concentration of KCI in the resulting solution.
<h3 /><h3>What are moles?</h3>
A mole is defined as 6.02214076 ×
of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
No.of moles of KCI


= 0.599 moles
Vol.of the solution,V= 500 ml
= 0.5 liter
Molarity


= 1.199 M
Hence, 1.199 M is the concentration of KCI in the resulting solution.

Answer:
co+ o2+ 2co2 is not balanced reaction
Answer:
See explanation below
Explanation:
In this reaction we have the ethyl acetoacetate which is reacting with 2 eq of sodium etoxide. The sodium etoxide is a base and it usually behaves as a nucleophyle of many reactions. Therefore, it will atract all the acidics protons in a molecule.
In the case of the ethyl acetoacetate, the protons that are in the methylene group (CH3 - CO - CH2 - COOCH2CH3) are the more acidic protons, therefore the etoxide will substract these protons instead of the protons of the methyl groups. This is because those hydrogens (in the methylene group) are between two carbonile groups, which make them more available and acidic for any reaction. As we have 2 equivalents of etoxide, means that it will substract both of the hydrogen atoms there, and then, reacts with the Br - CH2CH2 - Br and form a product of an aldolic condensation.
The mechanism of this reaction to reach X is shown in the attached picture.
