Answer: both numbers are 2
Explanation:
When potassium is added to water, the metal melts and floats. It moves around very quickly on the surface of the water. The hydrogen ignites instantly. The metal is also set on fire, with sparks and a lilac flame.
An example of a single replacement reaction occurs when potassium (K) reacts with water (H2O). A colorless solid compound named potassium hydroxide (KOH) forms, and hydrogen gas (H2) is set free.
Either covalent or ionic... they are nonmetals meaning that the are a component in both types of compounds
Answer:
Alkyl halides undergo <u><em>SN2</em></u> reactions with Brønsted-Lowry bases. An <u><em>ethene </em></u>is a sp² hybridized and trigonal planar and contains a vacant p orbital. All SN2 reactions proceed with <u><em>backside</em></u> attack of the nucleophile, resulting in <u><em>inversion</em></u> of configuration at a stereognic center. Spreading out charge by the overlap of an empty p orbital with an adjacent σ bond is called <u><em>hyperconjugation</em></u> . Equilibrium favors the products of nucleophilic substitution when the leaving group is a <u><em>weak</em></u> base than the nucleophile. According the to Hammond postulate, the stability of the <u><em>enthalpy</em></u> determines the rate of its formation. The formation of equal amounts of two enantiomeric products from a single starting material is called <u><em>racemic mixture</em></u> . A <u><em>lewis base</em></u> is an electron-rich compound, which donates a pair of electrons to an electron deficient compound, forming a covalent bond.
