A bond in which one atom contributes both bonding electrons to a covalentbond
yKpoI14uk [10]
<h3>Answer:</h3>

A coordinate bond

<h3>Explanation:</h3>
  • A chemical bond is a force of attraction between two or more atoms of elements.
  • Covalent bond is a type of chemical bond that occurs between non-metal atoms.
  • It occurs as a result of sharing of electrons between the non-metal atoms.
  • Atoms involved in covalent bond formation may contribute equally to the bond formation or the electrons shared may come form one of the atoms.
  • When the electrons shared in a covalent bond are derived from one atom, then the covalent bond is known as a coordinate bond.

What is the product when magnesium reacts with nitrogen? Mg(s) + N2(g) → Mg2N3(s) Mg3N(s) Mg3N2(s) MgN3(s)
bixtya [17]
Look at the periodic table to find the charge on atoms.
 Magnesium is +2 and Nitrogen is -3. Since there are two nitrogen charge 2*-3 = -6 there needs to be 3 Mg then (3*2+ = 6+) to pair with the two nitrogen.
3 Mg(+2) + 2 N(-3) = Mg3N2

What is the kinetic energy of a 2,000-kilogram ball that is on the ground
Finger [1]
Kinetic energy is associated with the motion of an object.
Since the object is at rest on the ground, its velocity is zero.
Since kinetic energy is directly proportional to the square of velocity, kinetic energy of the ball on the ground is zero.
