HELP 100 POINTS WILL MARK BRAINLIEST In ancient times, early astronomers watched stars travel across the sky in one direction for several months, then over the course of a few weeks the stars would reverse course and move in the opposite direction. After these few weeks, the stars would reverse direction again and resume their original course. The ancient astronomers called these “wanderer stars”. After more research was done, it was found that these “wanderer stars” were actually other planets. As more data was collected, it was shown that all planets move at different speeds as they travel in their orbits around the Sun. As the Earth moves in its orbit, it moves faster than some planets and slower than others. This causes the Earth to “pass” some planets as it travels, which results in the appearance that the other planets move backwards.

A. Reaction A.
B. Reaction B.
C. Reaction C.
D. Reaction D.
E. Reaction E.
F. Reaction F.
Answer: Reactions: A, B and F
Explanation: Gibbs Free Energy, symbol G, combines Enthalpy (sum of internal energy) and Entropy (measure of how much the energy of atoms and molecules become spread out in a process).
The change in free energy (ΔG) is the sum of enthalpy and the product of temperature and entropy of the system.
With free energy, it is possible to determine if a reaction is spontaneous, i.e., happens wthout external energy, or non-spontaneous.
If ΔG is negative, reaction is spontaneous. If ΔG is positive, reaction is non-spontaneous.
Analysing each ΔG of the reactions above, reactions A, B and F's Gibbs Free energy are negative, so these 3 are spontaneous.
A liquid containing 55.0 wt% methanol (M), 5.00 wt% polyacrylate (P), and 40.0 wt% water (W) is distilled at steady-state into a top steam and a bottom stream. The total mass flow rates of the top and bottom streams are the same. The top stream has 85.0 wt% M and 0% P. a. Can you set a basis of calculation in this problem? Why or why not? b. Calculate the composition (mass fractions) in the bottom stream.
Answer:
a) YES ( Basis : F=100kg/h)
b) composition mass fraction in the bottom stream
(Xm)B = 0.25
(Xp)B = 0.1
(Xw)B = 0.65
Explanation:
a)
Can you set a basis of calculation in this problem? Why or why not?
Yes we can set a basis if calculation in this problem.
A good basis makes the calculation more easier. the problem are given in weight basis so we can choose basis of feed rate of 100kg/h
BASIS : 100kg/h
b)
given that;
mass flow rate of M in the feeds Mf = 0.55*F = 0.55*100 = 55kg/h
mass flow rate of p in the feeds Pf = 0.05*F = 0.05*100 = 5kg/h
mass flow rate of W in the feeds Pf = 0.40*F = 0.40*100 = 40kg/h
Now Balance
F = T + B
( but T=B)
so F = T + T = 2T
B = T = 50kg/h
TOP
mass flow rate of M in the top Mt = 0.85*T = 0.85*50 = 42.5 KG/H
mass flow rate of P in the top Pt = 0kg/h
mass flow rate of W in the top Wt = 0.15*T = 0.15*50 = 7.5kg/h
balance on M
Mf = Mt + Mb
Mb = Mf - Mt = 55kg/h - 42.5kg/h = 12.5kg/h
Balance on P
Pf = Pb + Pt
Pb = Pf - Pt = 5kg/h - 0kg/h = 5kg/h
Balance on W
Wf = Wt + Wb
Wb = Wf - Wt = 40kg/h - 7.5kg/h = 32.5kg/h
So bottom composition
mass fraction of M in Bottom XmB = Mb/B = (12.5kg/g) / (50kg/h) = 0.25
mass fraction of P in Bottom XpB = Pb/B = (5kg/g) / (50kg/h) = 0.1
mass fraction of W in Bottom XwB = Wb/B = (32.5kg/g) / (50kg/h) = 0.65

Which of the following isotopes are NMR inactive?
a. 1H
b. 12C
c. 15N
d. 16o
e. 19F
f. 31P
Answer:
12C and 16O
Explanation:
Here, we want to select which of the options are NMR inactive. For an isotope to be NMR inactive, then the net nuclear spin is zero.
What this means is that the number of proton present coupled with the number of neutrons are an even number pair.
What we are saying here is that the number of protons is an even number while the number of neutrons too is an even number. So the net nuclear spin in this case is zero.
in the case of oxygen, we have 8 protons and 8 neutrons. This makes the nuclear spin zero and consequently makes the isotope NMR inactive.
Same is in the case of carbon. There are 6 protons and 6 neutrons and this also makes nuclear spin zero .
In all the other isotopes in the question, we have odd number even number or even number odd number pairs of protons and neutrons.
The measurement 3.8 x 10^3 g could also be written as
Right now it's written in scientific notation, so you can just move the decimal place in 3.8 to the right 3 times (as it is times 10 to the third power) to get 3,800g.
The measurement 3.8 x 10³ grams could also be written as 3.8 kilograms.
What is a unit of measurement?A unit of measurement is a specified magnitude of a quantity that is established and used as a standard for measuring other quantities of the same kind. It is determined by convention or regulation.
As given in the problem we have to convert the measurement of 3.8 x 10³ grams into some different units,
1000 grams = 1 kilograms
1 gram = 1 /1000 kilograms
3.8 x 10³ grams = 3.8 x 10³ ×1 /1000 kilograms
=3.8 kilograms
Thus, the measurement 3.8 x 10³ grams could also be written as 3.8 kilograms.

Aqueous hydrochloric acid HCl will react with solid sodium hydroxide NaOH to produce aqueous sodium chloride NaCl and liquid water H2O. Suppose 9.84 g of hydrochloric acid is mixed with 3.1 g of sodium hydroxide. Calculate the maximum mass of water that could be produced by the chemical reaction. Round your answer to 2 significant digits.
Answer:
1.4 g H₂O
Explanation:
In a reaction, the reactants are usually not present in exact stoichiometric amounts, that is, in the proportions indicated by the balanced equation. Frequently a large excess of one reactant is supplied to ensure that the more expensive reactant is completely converted to the desired product. Consequently, some reactant will be left over at the end of the reaction. The reactant used up first in a reaction is called the limiting reagent, because the maximum amount of product formed depends on how much of this reactant was originally present. When this reactant is used up, no more product can be formed.

Based on your observations of the laboratory assignment(s) that produced gases, can you conclude
that the same gas was produced in each assignment? Briefly explain.
Answer:
With the use of same chemicals, same gas will be produced while the use of different chemicals, different gases will be produced.
Explanation:
The same gas was produced in each assignment if the same chemicals are mixed with each other while different gases were produced in each assignment when different chemicals are allowed to mix. If every time, same chemicals and same concentration of chemicals are mixed together, the result will be the same means production of same gas but if different chemicals are allowed to mix, then the product will be the production of different gases.
