Answer:
F
Explanation:
When an atom lose or gain electrons ions are formed.
There are two types of ions. Cation and anion.
Cation:
Cations are formed when atom lose electrons. For example:
X → X⁺ + e⁻
Anion:
It is formed when an atom gain electrons. For example:
X + e⁻ → X⁻
Fluorine is present in group seventeen. It has seven valance electrons. It gain one electron to complete the octet and form anion with charge of -1.
Calcium is alkaline earth metal. It is present in group two it loses two valance electrons and form cation with charge of +2.
Neon is noble gas. It already have complete octet. It can not form ions. To remove the electrons from noble gases very high temperature is required.
Zinc is present in group 12. It usually form cation by losing its two valance electrons but it can also show oxidation state -2.
Answer:
The answer to your question is No, it is not.
Explanation:
Data
C₄H₁₀ + 13O₂ ⇒ 8CO₂ + 10H₂O
In a double replacement reaction, two reactants interchange cations an example of these reactions are neutralization reactions. In neutralization reactions, an acid and a base react to form a salt and water.
The reaction of this problem is not a double replacement reaction because the products are carbon dioxide and water, not a salt and water.
The reaction of this problem is a combustion reaction.
Answer:
The product is 1-methylcyclopentanol
Explanation:
The acid-catalyzed hydration of alkenes involves the addition of a water molecule to a C=C double bond.
H₂O + C=C ⟶ H-C-C-OH
An H atom adds to one of the C atoms, and an OH group adds to the other
This reaction follows Markovnikov’s rule — the H adds to the C atom that has more hydrogen atoms, and the OH adds to the more substituted carbon.
The steps of the mechanism are:
- The aqueous sulfuric acid generates hydronium ions
- The nucleophilic π electrons attack an H atom on the hydronium ion, forming a carbocation on the more substituted C atom.
- The lone pair electrons on a water molecule attack the carbocation , forming an oxonium ion.
- Another water molecule removes the extra proton.
The product is the alcohol with the OH group on the more substituted carbon — 1-methylcyclopentanol.
C) a fundamental force would be gravity
Answer:
Ionic bond occurs between two atoms that have different:
a) Electron
Explanation:
according to the definition of ionic bond,
it is the electrostatic force of attraction that holds the two oppositely charged ions together and an ionic bond or electrovalent bond is formed when one atom gains electrons while the other atom loses electrons from its outermost level or orbit.
