A) The first ionization energy of atomic F is lower than the first ionization energy of F,. This difference is observed because the atomic p orbitals of F are lower energy than bonding orbitals of F,. B) The first ionization energy of atomic F is lower than the first ionization energy of F,. This difference is because the bonding orbitals of the atomic species are lower energy than the bonding orbitals of the diatomic species. C) The first ionization energy of atomic F is greater than the first…

4. Gasoline can be reasonably approximated as C9H20 with a density of 0.718 g/mL. Diesel can be reasonable approximated as C14H30 with a density of 0.763 g/mL. (Both gasoline and diesel are complicated mixtures. These formulas are something like weighted averages of the formulas of the different components, where the weighting is based on various quantifiable behaviors. That is, using these artificial formulas for gasoline and diesel allows one to calculate average properties that match what petroleum engineers might measure.) The enthalpy change from burning one mole of gasoline is -6160 kJ. The enthalpy change from burning one mole of diesel is -7940 kJ. Determine which fuel generates the biggest enthalpy change per gram burned, and which generates the biggest enthalpy change per mL burned.

i think this is physics and chemistry so i hope you can help me to answer this, only TRUE OR FALSE

Environmental science is an interdisciplinary field of study. This means that.. * Multiple branches of science only (biology, chemistry, etc) are covered. Many science and non-science fields of study, such as economics and politics, are included. It is limited to only one branch of science; ecology. Each environmental issue is specific to only one type of science.

Well-supported theories can eventually become scientific law. O True statement O False statement

Real-World Chemistry 1. Suppose you wanted to ship bananas from Puerto Rico to New York and the time required for shipment was 8 days. Will you choose to ship ripe bananas or green bananas? Why? 2. You may have heard the saying "One bad apple will spoil the whole barrel." Based on the results of | your experiment, do you think the statement may be true? Why?

Answer number 1-4 pls. I don't want to waste my money here.

What is wrong with the expression “That is just a theory,” if by theory the speaker is referring to a scientific theory?

formulate a hypothesis. the hypothesis can be about anything.
