How is electron movement related to covalent bonding in
ammonia, NH3?
A) Electrostatic
sharing in a sea of electrons around the atoms allows bonds to form.
B) The atomic orbitals overlap and electrons are shared between the atoms
forming bonds.
C) A transfer of electrons forms ions which are electrostatically attracted
forming bonds.
D) Orbital exchange occurs between the atoms to redistribute the electrons and
form bonds.
The electron
movement related to covalent bonding in ammonia, NH3 is The atomic orbitals overlap and electrons are shared between the atoms
forming bonds. The answer is letter B.
Answer:
THE MOLARITY OF THE SOLUTION IS 3.36 MOLE/L
Explanation:
First we must understand what molarity is.
Molarity is the number of mole per unit volume of solution. In this question, 9.25 mole of H2SO4 was given in 2.75 L of solution.
Molarity is written in mole per dm3 or L.
So we can calculate the molarity:
9.25 ole of H2SO4 = 2.75 L of solution
The number of mole in 1 L of solution will be:
= 9.25 mole / 2.75 L
= 3.3636 mole/ L
In conclusion, the molarity of the solution is approximately 3.36 mole/L
Answer:C. Hydrogen Bonds with themselves and entropy decreases.
Explanation:Limonene is a chiral aliphatic Hydrocarbon liquid that is relatively stable as MONOTERPENE which cracks at high temperature to produce ISOPRENE. D-limonene is produced from CITRUS FRUIT through CENTRIFUGAL SEPARATION AND STEAM DISTILLATION. The most widely used conversion of limonene is to CARVONE.
The water molecules around LIMONENE forms Hydrogen Bonds with themselves and entropy of the reaction decreases,the name Limonene was obtained from the PEEL OF LEMON.
Did you ever find out the answer I'm in dier need
Answer:
C) cation, loses, anion, gains
Explanation:
Lithium is a metal from Group 1, so it has 1 valence electron. Thus, it loses 1 electron to complete its octet and form the cation Li⁺.
Oxygen is a nonmetal from Group 16, so it has 6 valence electrons. Thus, it gains 2 electrons to complete its octet and form the anion O²⁻.
In the reaction between Li and O, there is a transfer of electrons making an ionic bond. In the bond, lithium would be a cation because it loses an electron, and oxygen would be an anion because it gains 2 electrons.
