the down arrow. :)

What chemical formula represents a diatomic molecule

a diatomic molecule is a molecule with two atoms. so H2 is a diatomic molecule. HCl is also a diatomic molecule. C4H6 is not a diatomic molecule, because it has more then 2 atoms

Why it is said relativistic quantum mechanics

The distinction is sometimes made to distinguish normal quantum mechanics (which does not incorporate special relativity) and quantum field theory (relativistic quantum mechanics).

Since we know special relativity is correct it is the relativistic form of quantum mechanics which is true, but non-relativistic quantum mechanics is still used, because it is a good approximation at low energies and it is much simpler.

Physics students typically study regular quantum mechanics before moving on to quantum field theory.

The letter E in a VSEPR formula represents the

It stands for electron.

VSEPR formulas would predict a tetrahedral shape

AX4

VSEPR formulas would predict a trigonal planar shape

AX3

When two electrons are shared between atoms it is said to be a covalent bond

Yes, when electrons are shared, it is said to be a covalent bond.

How many joules of energy are necessary to heat a sample of water with a mass of 46.0 grams for 0.0

46 calories (or 192, 464 joules) for each Celsius degree.

Which of these pairs of elements would most likely form non-polar covalent bonds Al and Br or Zn and Br or Br and Br or H and H

Both Br and Br and H and H form non-polar covalent bonds.

Is lactic acid a monoprotic acid

yes. it is monoprotic acid

Choose the best definition for this symbol. (s)
