Answer:
a) Mg and S = atoms
b) H2 SO3 = molecules
c) HBr =molecule
Explanation:
Step 1: Data given
Atoms = An atom is the smallest constituent unit of ordinary matter that constitutes a chemical element. We can find them on the periodic table.
Molecules = A molecule is an electrically neutral group of two or more atoms held together by chemical bonds.
a. Mg S = Magnesium and sulfur both are atoms, we both can find them on the periodic table
b. H2 SO3 = H2 is a molecule that contains 2 hydrogen atoms
SO3 is a molecule that contains 1 sulfur atoms and 3 oxygen atoms
c. HBr = HBr is a molecule that contains 1 hydrogen and 1 bromine atom

Answer:
A. 0.65g/mL, float
Explanation:
Mass: 325g
Volume: 500mL
D = m/v
D = 325/500
D = 0.65
Therefore, the block has a density of 0.65g/mL and it will float since the density of water is greater than the density of the block.

To see an exponent that's negative, write .00000031 in scientific notation.<span>Move the decimal place to the right to create a new number from 1 up to 10. So, N = 3.1.Determine the exponent, which is the number of times you moved the decimal. ...Put the number in the correct form for scientific notation.</span>How to Write Numbers in Scientific Notation - dummies<span>www.dummies.com/education/math/.../how-to-write-numbers-in-scientific-notation/
