Answer:
12,096 mg of antibiotics
Explanation:
cuz honeyyy:
160lb=72 kg
6mg twice a day so daily 12mg
12mg per kg so 12×72 =864
for 14 days is :864×14=12,096
2) Gay-Lussac's law shows a direct relationship between temperature and
O moles
pressure
O volume
O density
Answer:
The correct option is (b) "pressure".
Explanation:
Gay-Lussac's law states that the pressure of an ideal gas is directly proportional to its temperature at constant mass and volume.
Mathematically, Gay-Lussac's law is as follows :
[tex]P=kT[/tex]
or
[tex]\dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}[/tex]
Hence, the correct option is (b) "pressure".

What is the name of this compound?
Answer:
THERE IS NOTHING MENTION HERE HOW CAN ANYONE KNOW ABOUT IT?]
Explanation:
Give an example that illustrates the importance of chirality in a named biological molecule.
Answer:
Chirality is a particularly important concept in biology, because cells are mostly composed of chiral molecules. Small chiral molecules such as amino acids and sugars (figure 1, top) are the building blocks of larger molecules, such as proteins and nucleic acids, which are also chiral
In carrying out an analysis of a mixture, what do you expect to see when the TLC plate has been allowed to remain in the developing chamber too long, so that the solvent front has reached the top of the plate
Answer:
See explanation
Explanation:
In TLC, the plate is spotted at a point above the solvent front and the solvent moves up the plate by capillary action leading to the separation of the various components of the mixture spotted on the plate.
However, if the TLC plate is allowed to remain in the developing chamber for too long such that the solvent front reaches the top of the plate, the components of the mixture will recombine at the top of the plate and cancel out any separation which may have occurred on the plate.
A 200. gram sample of a salt solution contains 0.050 grams of NaCl. What is the concentration of the
solution in parts per million (ppm)?
Answer:
2.5 × 10² ppm
Explanation:
Step 1: Given data
Mass of NaCl: 0.050 gMass of the sample: 200. gStep 2: Convert 0.050 g to μg
We will use the conversion factor 1 g = 10⁶ μg.
0.050 g × 10⁶ μg/1 g = 5.0 × 10⁴ μg
Step 3: Calculate the concentration of NaCl in ppm
The concentration of NaCl in ppm is equal to the micrograms of NaCl per gram of the sample.
5.0 × 10⁴ μg NaCl/200. g = 2.5 × 10² ppm
Answer:250 ppm

What is the molar concentration of 1.29 mol of KCL dissolved in 350 mL of solution?
Answer:
M = 3.69 M.
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to calculate the molar concentration of the 1.29 moles of KCl in 350 mL of solution by recalling the mathematical definition of molarity as the division of the moles by the volume in liters, in this case 0.350 L; thus, we proceed as follows:
[tex]M=\frac{1.29mol}{0.350L}\\\\M=3.69M[/tex]
Which gives molar units, M, or just mol/L.

why is tin tin and aluminum the better choice for canned milk
Answer:
Well, they are very durable unlike other packaging food materials, they can be recycled. But, the internet says allumninum cans are much better. and it could be better because you can keep the canned milk cool (cold) for a long lasting time. (keep it in the fridge if you want it to stay cold even longer)

Arrange the following molecules in order of decreasing polarity of their bonds.
a. PBr3
b. SF2
c. H2O
d. NCl3
Answer:
SF2 > H2O > PBr3 > NCl3
Explanation:
Compare the electronegativity values for the atoms and classify the nature of the bonding based on the electronegativity difference.
P has an electronegativity of 2.1, while Br has an electronegativity of 2.96. The difference is 0.86, indicating that these atoms will form covalent bonds.
S has an electronegativity of 2.58 while F has an electronegativity of 4.0. The difference is 1.42, indicating that these atoms will form polar covalent bonds.
O has an electronegativity of 3.5 while H has an electronegativity of 2.1. The difference is 1.4, indicating that these atoms will form polar covalent bonds.
N has an electronegativity of 3.04, whereas Cl has an electronegativity of 3.5. This difference of 0.46 indicates that these atoms will form covalent bonds.
We know that the greater the electronegativity, the higher the polarity. In decreasing order of polarity, we have:
SF2 > H2O > PBr3 > NCl3

By knowing the natural abundance of minor isotopes, it's possible to calculate the relative heights of M+ and M+1 peaks. If natural abundances are 12C - 98.9% and 13C - 1.10%, what are the relative heights, to the nearest 0.1%, of the M+ and M+1 peaks in the mass spectrum of cholesterol, C27H48O? Ignore the contributions of isotopes like 2H (deuterium; 0.015% natural abundance) and 17O (0.04% natural abundance) that are small. The relative heights are, in order of increasing mass: 100 to
Answer:
the relative height of M⁺ : M+1 is; 0.7418 : 0.2228
The relative heights are; In order of increasing mass 100 : 30
Explanation:
Given the data in the question;
The M⁺ peak comes from all ¹²₆C atoms
so, the probability in cholesterol, C₂₇H₄₈O is ( 98.9% )²⁷ = ( 0.989 )²⁷ = 0.7418
The M+1 peak comes from the isotopic carbon ¹³₆C.
so, the probability in cholesterol is ⇒ 1.10% × ( 98.9% )²⁶ = 0.011 × ( 0.989)²⁶
The probability for 27 carbons is ⇒ 27 × 0.011 × ( 0.989)²⁶ = 0.2228
Therefore, the relative height of M⁺ : M+1 is; 0.7418 : 0.2228
The relative heights are; In order of increasing mass 100 : 30

A student obtains a beaker containing a solution that is determined to have a hydrogen ion
concentration (H+) of 6.7x10-14. Based on this information, please answer the following
questions:
a) What is the pH of the solution?
b) is the solution acidic, neutral or basic?
Answer:
pH = 13.1
Basic
Explanation:
Step 1: Given data
Hydrogen ion concentration ([H⁺]): 6.7 × 10⁻¹⁴ M
Step 2: Calculate the pH of the solution
We will use the definition of pH.
pH = -log [H⁺]
pH = -log 6.7 × 10⁻¹⁴ = 13.1
When pH < 7, the solution is acid.When pH = 7, the solution is neutral.When pH > 7, the solution is basic.Since pH > 7, the solution is basic.
