Elements in the same group have the same amount of electrons, this affects bonding because it determines how much the element will "want" to form a covalent bond.
Ionic bonding does not involve the sharing of electrons, that one is false. In ionic bonding, the metal's electrons are given to the non-metal, so that they're both like the nearest noble gas (full electron shells.) They are then drawn together because one has a negative charge (the non-metal) and one has a positive charge (the metal.)
Oxide ions have a 2+ charge: This is false, oxide ions have a 2- charge.
Electrons do have a negative charge, this is true.
Hydrogen molecule: pretty sure this is true. We know this because both atoms are non-metals.
The last one is true: a covalent bond is a shared pair of electrons between two atoms, however be aware that there can be more than one covalent bond between two molecules.
Answer:
Add more substrate.
Explanation:
First let's explain why all the other options are wrong:
- The problem states that we <u>have optimum pH and optimum temperature</u>, this means that any change to those factors (increasing or decreasing) would slow down the reaction.
- <u>An inhibitor is called that way because its presence slows downs the reaction</u>, so more inhibitor would not speed up the reaction.
A <em>competitive inhibitor</em> is a substance that resembles the substrate that normally reacts with the enzime, so it binds to the enzime's active sites and prevents the substrate from doing so. Adding more substrate makes it more likely than a substrate molecule binds to an enzime's active site instead of the inhibitor ("it will outcompete the inhibitor and increase the reaction rate").
