Consider the gas-phase equilibrium A ? B. In a series of experiments, different initial amounts of A and B are mixed together, a

nd the mixture in each case allowed to come to equilibrium. Which one of these experiments would yield values for the amounts of A and B present at equilibrium different from all the other experiments?
a. 3.0 moles A, 4.5 moles B

b. 4.5 moles A, 3.0 moles B

c. 1.5 moles A, 4.5 moles B



d. 7.5 moles A, no B

B. the radioactive atom decays by alpha emission. write an equation showing the decay. (1 point)
zalisa [80]

alpha decay is an emission of ₂⁴He nucleus. If an element undergoes an alpha decay, the mass of the daughter nucleus formed is reduced by 4 compared to mass of parent atom and atomic number is reduced by 2 compared to atomic number of parent atom.

Let's assume that the parent atom is X, atomic number is z and mass number is A. Then the formed daughter nucleus, Y should have atomic number as z-2 and mass number as A-4.

The equation is

(z) (A)X → ₂⁴α + (z-2)(A-4)Y


Example:

₉₄²³⁹Pu → ₂⁴α + ₉₂<span>²³⁵U</span>

If you need to reverse the following reaction and multiply it by 2 in order for it to be an intermediate reaction in a Hess's la
k0ka [10]
The reaction is:
C₂H₄ + 3O₂ → 2CO₂ + 2H₂O; ΔH = 1410 kJ

When we reverse this reaction, the sign of the enthalpy  change, ΔH, will be changed. The enthalpy change for the reversed reaction would be 1,410 kJ.
Next, we must also multiply the reaction by 2, so the final enthalpy change for the reverse reaction will be:

ΔH = 2,820 kJ

Is saturated fat the same as trans fat?
Oduvanchick [21]

Answer:

Saturated fat occurs naturally in red meat and dairy products. It's also found in baked goods and fried foods. Trans fat occurs naturally in small amounts in red meat and dairy products. Trans fat can also be manufactured by adding hydrogen to vegetable oil.

A compound with molecular formula C6H15N exhibits a singlet at d 0.9 (1H), a triplet at d 1.10 (3H), a singlet at d1.15 (9H), an
LuckyWell [14K]

Answer:

N-ethyl-2-methylpropan-2-amine

Explanation:

 

In this case, we have to start with the <u>IR info</u>. The signal on 3400 cm^-1 indicates the presence of a <u>hydrogen bonded to the heteroatom</u>. In this case, we have nitrogen in the formula, so we will have the <u>amine group</u>.

On the other hand, we have to analyze the NMR info:

a)  We have 2 singlets => This indicates the presence of 2 different hydrogens without neighbors.

b) We have a triplet => This indicates the presence of <u>CH3 bonded to a CH2</u>.

c) We have a quartet => This indicates the presence of <u>CH2 bonded to a CH3</u>.

From b) and c) we can conclude that we have the <u>ethyl group</u> bonded to a nitrogen.  

Finally, we have to add 4 more carbons in such a way that we only have a single signal. In this case the <u>ter-butyl group</u>.

In that way, we will have <u>2 singlets</u> (from the CH3 groups in the ter-butyl and the H on the N). Also, we will have the <u>quartet </u>on the CH2 in the ethyl group and the <u>triplet</u> on the CH3 in the ethyl group
