Whereas semidiurnal tides are observed at the equator at all times, most locations north or south of the equator experiencetwo unequal high tides and twounequal low tides per tidal day; this is called a mixed tide and the difference in height between successive high (or low) tides iscalled the diurnal inequality.
Answer:
what
Explanation:
Which statement correctly describes how the parts of a flowering plant contribute to its survival? A. Roots prepare the plant for seed production, while the stem releases pollen for fertilization. B. Sepals prepare the plant for pollination, while the leaves collect oxygen for photosynthesis. C. Petals are involved in the reproductive cycle, while stamens protect the plant from predators. D. Ovaries are involved in fertilization and seed production, while anthers and

Answer:
These two are equivalent and valid:
Explanation:
The molecular superscripts for each atom in the <em>molecular formula</em> are determined by the number of times that the mass of the<em> empirical formula</em> is contained in the<em> molar mass</em>.
<u />
<u>1. Determine the mass of the empirical formula:</u>
:
Atomic masses:
- O: 15.999g/mol
- C: 12.011g/mol
- N: 14.007g/mol
- Cl: 35.453g/mol
Total mass:
- 15.999g/mol + 12.011g/mol + 14.007g/mol + 35.453g/mol = 77.470g/mol
<u />
<u>2. Divide the molar mass by the mass of the empirical formula:</u>
- 232.41g/mol / 77.470g/mol = 3
<u>3. Multiply each superscript of the empirical formula by the previous quotient: 3</u>

You might also write CN as a group:
