According to VSEPR theory, the structure of the ammonia molecule, NH3, is linear.
So your answer is B) linear
Answer:
B. A covalent bond has a lower potential energy than the two separate atoms.
Explanation:
<em>Identify the correct statement. </em>
<em>A. It is not possible for two atoms to share more than two electrons.</em> FALSE. Atoms also can share 4 electrons (double bond) or 6 electrons (triple bond).
<em>B. A covalent bond has a lower potential energy than the two separate atoms.</em> TRUE.
<em>C. Single bonds are shorter than double bonds.</em> FALSE. Single bonds are longer than double bonds.
<em>D. A covalent bond is formed through the transfer of electrons from one atom to another.</em> FALSE. In covalent bonds, electrons are shared, not transferred from one atom to another.
<em>E. A pair of electrons involved in a covalent bond are sometimes referred to as lone pairs.</em> FALSE. Lone pairs are those that do not participate in a bond.
Answer:The first thing you need to do here is to use the molarity of the solution to determine how many moles of sodium chloride you have in your sample.
As you know, molarity tells you the number of moles of solute, which in your case is sodium chloride, present in "1 L" of solution. This means that a "0.75 M" sodium chloride solution will contain 0.75 moles of sodium chloride for every "1 L" of solution.

Answer:
Activation Energy
Explanation:
The main cause of slowness to start a reaction is the value of it activation energy. When metals possess low activation energy, it takes them time to start a reaction. But once started, the reaction becomes vigorous.
Activation Energy: the minimum quantity of energy which the reacting species must possess in order to undergo a specified reaction.
