The molecular mass of octane is 114.22 g/mol. What is the mass of 22.05 mol of octane?

Answers

Answer 1
Answer: In this item, we are asked to calculate for the mass of 22.05 mole of octane given that its molecular mass is equal to 114.22 g/mol. To answer this item, we simply have to multiply the number of moles with the molecular mass. That is, (114.22 g/mol)(22.05 mol) which is equal to 2518.221 grams.
Answer 2
Answer: In order to compute the mass of a substance, we may simply mulitply the number of moles of the substance by the molar mass of the substance, since molar mass is mass per mole. Therefore, we get: 114.22 * 22.05 = 2,518.55 grams 2,518.55 grams of octane are present.

(10 points)Which of the following has the highest energy photons?
X-rays, Heat lamps, microwaves, gamma rays

Answers

Gamma rays have the highest energy photons among the options provided.

What are Photons

Photons are packets of energy associated with electromagnetic radiation. The energy of a photon is directly related to its frequency or inversely related to its wavelength. The higher the frequency or the shorter the wavelength, the higher the energy of the photon.

Gamma rays have the highest frequency and shortest wavelength among the given options, which corresponds to the highest energy photons.

Another name for the activated complex is _____.a. energy barrier
b. transition state
c. rate limiter
d. collision group

Answers

Answer:

                   Another name for the activated complex is Transition State.

Explanation:

                     According to Collision Theory for a chemical reaction to occur the reactants must collide with proper orientation and required energy. In this way the old bonds are broken and new bonds are formed. The mid point of highest energy at which both bond formation and breakage is taking place is called activation complex, a complex in between reactant and product.

                      The energy of this complex is the minimum amount of energy required for a particular reactants to convert into products and is called as Activation Energy.

                      This activation complex is also termed as Transition State because according to Transition State Theory at transition state the existing bonds tend to increase in length and become weaken while, the new forming bonds tend to decrease in length and start becoming stronger. Hence, the activated complex is in transition between reactants and products.

The apparent westward movement of a planet against the background of stars is called ____. (1 point)retrograde motion
revolution
rotation
universal gravitation

Answers

Answer:

retrograde motion  

Explanation:

All the planets have direct motion or progade motion i.e. they move in eastward direction around the Sun. The exceptions are Venus and Uranus which apparently move westwards. This is type of motion is known as retrograde motion. Venus and Uranus move opposite to the other planets motion against the background of stars.

Answer:

retrograde motion
