Answer:
The correct option is: d. trigonal planar
Explanation:
Sulfur trioxide is a chemical compound and the chemical formula of the compound is SO₃. In this molecule, the sulfur atom is in its +6 oxidation state and is covalently bound to three oxygen atoms. Sulfur trioxide is a neutral molecule. According to the VSEPR theory, Sulfur trioxide has a<u> trigonal planar molecular geometry.</u>
C. boiling point
boiling point is the temperature at which all liquids change from liquid to gas
Answer:
Explanation:
The half life of a radioactive atom is the time taken for half of the radioactive nuclei to disintegrate. The shorter the half life, the faster a radioactive nuclei decays.
Half life is often expressed as:
Half life = 
Where λ is the decay constant.
Answer:
A. While inconsistent, his average of 1.0 kg made his results quite
accurate
Explanation:
Accuracy is how close the value you gain from test or observation compared with the real value. In this test, all tests relatively close to 1kg and the average of the test is 1kg so this tool can be considered quite accurate.
The precision determines how close the value of multiple repetitions of the test. In this case, the value varies from 0.8kg to 1.2kg. The highest value is about 50% higher than the lowest value, so the range is pretty far and the test can be considered not precise.
