The atomic masses of elements are generally not whole numbers. Explain why.
Answer:
Because elements have isotopes.
Explanation:
So the atomic mass is the average of an element's isotopes.
Answer:
The atomic masses of most elements are not whole numbers, because they are a weighted average of the mass numbers of the different isotopes of that element, with respect to their abundances in nature.

What determines how many of each ion is required for an ionic compounds?
please do not look up on google!!!!
Each ion has a single charge, one positive and one negative, so we need only one ion of each to balance the overall charge. When writing the ionic formula, we follow two additional conventions: (1) write the formula for the cation first and the formula for the anion next, but (2) do not write the charges on the ions.

Read this passage from "The Secret Life of Walter Mitty."
"Puppy biscuit," said Walter Mitty. He stopped walking and the buildings of Waterbury rose up out of the misty courtroom and surrounded him again.
A woman who was passing laughed. "He said ‘Puppy biscuit,’" she said to her companion. "That man said ‘Puppy biscuit’ to himself."
What does the dialogue in the excerpt show about Mitty?
He is awkward and absentminded.
He is responsible and conscientious.
He is funny and entertaining.
He is sour and nasty.
Answer:
He is awkward and absentminded.
Explanation:
"The Secret Life of Walter Mitty" by James Thurber presets the story of Walter with a dream. The beginning of the story reflects on the idea that the story is more inclined towards the dreams and fantasy-full world rater than reality. Walter's dreams are a mixture of reality and his imagination. He spoke certain words those do not have meaning in reality. He calls himself 'Puppy Biscuit" to which the women reacted with a laugh. This represented his absent-minded character and his appeal towards is dreams.

medicine some chemical components (chemical formula)
Answer:
A chemical formula is a way of presenting information about the chemical proportions of atoms that constitute a particular chemical compound or molecule, using chemical element symbols, numbers, and sometimes also other symbols, such as parentheses, dashes, brackets, commas and plus (+) and minus (−) signs.
Compounds used as medicines are most often organic compounds, which are often divided into the broad classes of small organic molecules (e.g., atorvastatin, fluticasone, clopidogrel) and "biologics" (infliximab, erythropoietin, insulin glargine), the latter of which are most often medicinal preparations of proteins
Explanation:
choose the letter that best describes the behavior of a substance during a phase change:
/A/ neither absorbs or releases energy
/B/ always absorbs energy
/C/ always releases energy
/D/ either absorbs or releases energy
Answer:
/D/ either absorbs or releases energy
Explanation:
During a phase change energy is either absorbed or released.
A phase change is a reversible process which occurs when a substance changes is its state from one form to another.
Phase changes are used to delineate physical changes.
A phase diagram provides a graphic representation of the change. The diagram can be 2 dimensional or 3 dimensional.Calculate the heat that must be supplied to
a 532 , stainless steel vessel containing 375 g
of water to raise its temperature from 35 C
to the boiling point of water 100°C. Cs. =0.51 J/g. degrees C
Answer in units of J.
Q must be supplied = 119523.3~J
Further explanationThe law of conservation of energy can be applied to heat changes, i.e. the heat received/absorbed is the same as the heat released
Q in = Q out
Heat can be calculated using the formula:
Q = mc∆T
Q = heat, J
m = mass, g
c = specific heat, joules / g ° C
∆T = temperature difference, ° C / K
So from the question :
Q to the system(Q supplied) = Q water + Q steel vessel(Q gained)
[tex]\tt Q~supplied=m.c\Delta T(water)+m.c\Delta T(vessel)\\\\Q~supplied=375\times 4.18\times (100-35)+532\times 0.51(100-35)\\\\Q~supplied=101887.5+17635.8=119523.3~J[/tex]
Scientists and nutritionists have long suspected that high-fructose corn syrup, used to
sweeten soft drinks, is one of the causes of childhood obesity. In a recent study, at the
University of Cincinnati, researchers found that mice that drank water with added
fructose ate less solid food, gained more weight, and put on 90% more body fat than
mice that drank only water. Scientists concluded that fructose may affect metabolism in
a way that favors fat storage.
What is the independent variable?
The mice that drank only water
The presence of fructose in their diet
The quantity of water provided
The weight gained by the mice
Answer:
The presence of fructose in their diet
Explanation:
The independent variable in an experiment is the type of variable which is changed at intervals in order to study if it has a direct effect on the dependent variable.
The dependent variable in the experiment is the amount of weight gained by the mice in each group and the control group is the mice who drank the water without the fructose added.
A 1.00-L flask is filled with 1.00 moles of H2 and 2.00 moles of I2. The value of the equilibrium constant for the reaction of hydrogen and iodine reacting to form hydrogen iodide is 50.5 under the given conditions. What are the equilibrium concentrations of H2 , I2 , and HI in moles/L? H2 (g) + I2 (g) ⇌ 2HI(g)
Answer:
[tex] C_{H_{2}} = 0.07 M [/tex]
[tex] C_{I_{2}} = 1.07 M [/tex]
[tex] C_{HI} = 1.86 M [/tex]
Explanation:
The reaction is:
H₂(g) + I₂(g) ⇄ 2HI(g)
Initially, we have the following concentrations of H₂ and I₂:
[tex] C_{H_{2}} = \frac{n}{V} = \frac{1 mol}{1.00 L} = 1 mol/L [/tex]
[tex] C_{I_{2}} = \frac{n}{V} = \frac{2 mol}{1.00 L} = 2 mol/L [/tex]
Then, in the equilibrium we have:
H₂(g) + I₂(g) ⇄ 2HI(g)
1-x 2-x 2x
[tex] Kc = \frac{[HI]^{2}}{[H_{2}][I_{2}]} = \frac{(2x)^{2}}{(1-x)(2-x)} [/tex]
[tex] 50.5*(1-x)(2-x) - (2x)^{2} = 0 [/tex]
By solving the above equation for x we have:
x₁ = 2.32 and x₂= 0.93
Hence, the concentrations of H₂, I₂ and HI are:
[tex] C_{H_{2}} = 1-x = 1 - 0.93 M = 0.07 M [/tex]
[tex] C_{I_{2}} = 2-x = 2 - 0.93 M = 1.07 M [/tex]
[tex] C_{HI} = 2*x = 2*0.93 M = 1.86 M [/tex]

A piece of metal of mass 27 g at 93° C is placed
in a calorimeter containing 59.2 g of water at
21°C. The final temperature of the mixture is 34.9 ° C. What is the specific heat capacity of the metal? Assume that there is no energy lost to the surroundings.
Answer in units of J/g. ° C
Answer:
1.586 J/g°C
Explanation:
So, we have the formula [tex]q = mc\Delta t[/tex].
Since heat released by the metal is = to the heat absorbed by the water (because they eventually become the same temperature in solution), we can say
[tex]m_{water}C_{water}(T_{water}-T_f) = - m_{metal}C_{metal}(T_{metal} - T_f)[/tex]
Plugging in, we get:
[tex]59.2*4.184*(21- 34.9) = - 27*C_{metal}*(93 - 34.9)[/tex]
Solving, we get [tex]C_{metal} = 1.586[/tex] J/g°C.

You have a solution of water and pure ethanol. The boiling point of water is 100 degrees Celsius and the boiling point of pure ethanol is 78 degrees Celsius. A. What process would you would use to separate this solution? Describe, in detail, how this process works.
Answer:
Distillation
Explanation:
A solution of water and ethanol are miscible. Hence, they can only be separated by a process known as distillation. Distillation is the process in which two or more constituents in a mixture are separated based on there difference in boiling points. The mixture is subjected to high heat and the one with the least boiling point distills/evaporates out first followed by the next least boiling point.
From the explanation above, it can be deduced that ethanol (with boiling point of 78°) will be distilled out while water remains in the boiling tube or container.

When exposed to very high temperatures, metals like iron can be turned into fluids that flow and can be poured into molds. What happens within the iron to allow it to flow?
A) The energy of the solid decreases, and the particles begin to collide with high frequency
B)The energy of the solid increases, and the particles begin to slide past each other
C)The solids collide at an increasing rate until reaching equilibrium energy
D)The particles vibrate about equilibrium in an effort to minimize energy
Answer: B) The energy of the solid increases, and the particles begin to slide past each other.
Explanation:
The energy of the solid matter is required to be increased so that molecules of the solid matter get separated from each other and an transition from solid matter to liquid matter occurs. The liquid components of the matter will slide past each other as they have obtain energy for fluidity. The liquid iron can be molded into any shape and the energy decreases considerably.
