Answer: 85.62 L represents volume (V).
Explanation:
Volume is defined as the amount or quantity of a given substance or an object.
According to ideal gas equation:
P = pressure of gas = 4.95 atm
V = Volume of gas = 85.62 L
n = number of moles
R = gas constant =
T =temperature =
Thus 85.62 L represents volume (V).
To solve this kinematics formula use the following equation:
Vf = Vi + at
Vf = 0 + (9.81 m/s^2)(3 seconds)
Vf = 29.43 m/s and or about 29.4 m/s of reported to 3 significant figures.
Answer:
Component P, because being supported by ample evidence is a characteristic of a theory.
Explanation:
Hypothesis do not explain phenomenon they are just educated guesses that can be put into work to see if they are true of false.
Scientific theory on other hand, is widely accepted and supported by large amount of evidence and useful for explaining scientific phenomenon.
Answer:
(B) the energy required to break apart one mole of an ionic compound into its gaseous ions
Explanation:
Lattice energy is the energy that would be obtained from the formation of an ionic compound from its gaseous ions. Therefore, the reverse process that responds the question would be the energy required to break apart an ionic compound and convert its component atoms into gaseous ions.
Lattice energy provides a measure of the stability of an ionic compound. When the ions bind to form the crystalline structure, heat (energy) is released. To break the ionic compound into the ions that form it, it is necessary to provide an energy equal to that released when formed, i.e. the lattice energy.
Answer:
2-methylene propylbenzene
Explanation:
The Wittig Reaction is a reaction that converts aldehydes and ketones into alkenes through reaction with a phosphorus ylide.
The ketone in this case is 1-phenylpropan-1-one. The provided phosphonium ylide is shown in the image attached. The reaction involves;
i) alkylation
ii) addition
The product of the major organic product of the reaction is 2-methylene propylbenzene.
