Answer:
5496 g of epinephrine
Explanation:
From the question, 5.00 moles of epinephrine is required to make Epipen.
Molar Mass of epinephrine = 183.20 g/mol
mass of 5 moles of epinephrine= [tex]5.00 moles * 183.20 g/mol=916 g[/tex]
Therefore, 30.00 moles of epinephrine needs 30.00 * 916/5 =5496 g of epinephrine
Take a good look at the head lights and tail lights of your family vehicle . How does the shape of the lenses of each and the reflectors aid the light emitted ?
Answer: The shape lets you see a wide area but not blind everyone that is ahead of you though some vehicles are tall and do so anyways or are too close and the reflections make sure the light is brighter forward than to the sides so it can be more effective for seeing in the dark or even during storms.

The units used on the U.S. freshwater withdrawals, 1950-2015 map are listed as Mgal/d. One million gallons of water per day (Mgal/d), covers a football field with about ___ feet of water.
Question 8 options:
0.5
1.2
2.8
5.8
Based on the conversion factor from gallons to cubic foot, one million gallons of water per day will cover a football by 2.3 feet.
What is the conversion from gallons to cubic foot?To convert from gallons to cubic foot the following conversion factors are used:
I gallon = 0.134 cubic foot1 million gallon = 134000 cubic footThe standard area for an American football field = 57,600 square feet
The height which one million gallons of water per day 15(Mgal/d), covers a football will then be:
Height = 134000 cubic foot / 57,600 square feet
Height = 2.3 feet.
Therefore, one million gallons of water per day will cover a football by 2.3 feet.

Explanation:
Assuming all solvents are suitable to recrystallize the desired product, which solvent is best for removing the impurity through a hot filtration
The solvent that is best for removing the impurity through hot filtration is petroleum ether. It is an organic solvent.
What is Petroleum ether?Petroleum ether is an organic solvent derived from petroleum, i.e., it is a well-known aliphatic hydrocarbon.
Petroleum ether is not a true ether because the word 'ether' makes reference to its extremely high level of volatility.
Moreover, hot filtration is a chemical methodology used for filtering solutions that are able to crystallize when they cool.

Water is your body's principal chemical component and makes up about 60 percent of your body weight. Your body depends on water to survive. About 20 percent of daily fluid intake usually comes from food and the rest from drinks.The formula to water intake calculator is:c=[w∗ f∗ g+12∗ m30]/8 where:c = fluid amount in cupsw = weight in poundsf = age factor (0.642 for age < 30; 0.56 for 30 < age < 55; 0.481 for age > 55)g = gender factor (1 for male; 0.73 for female)m = exercise time in minutesExample 1: Find the water intake amount for a male of 20 years old, weight 158 pounds, exercise 50 minutes dailySolution: w = 158, f = 0.642 (age < 30), g = 1 (male), m = 50 cups
Answer:
Explanation:
According to the formula provided in the question, the formula for water intake amount is C = [w × f × (g+12) × m × 30]/8
where c is the fluid amount in cups
w is the weight in pounds (158 pounds)
f is the age factor (0.642 because the age is below 30)
g is the gender actor (1 because the individual is a male)
m is the exercise time in minutes (50 minutes)
c = 158 × 0.642 × (1 + 12) × 50 × 30/8
c = 1978001.99/8
c = 247250.25 cups

A glass cylinder contains four liquids in four separate layers. One liquid is water. The purple liquid has a density 1.62 g/cm3. The yellow liquid has a density of 0.46 g/cm3. The red has a density of 0.91 g/cm3. What is the order of the liquids in the cylinder? Explain your answer. What will happen if you slip a small, flat, chip of wood (density 0.85 g/cm3) into the cylinder?
Answer:
The order of the liquids in the cylinder will be yellow liquid, followed by red liquid, water & lastly purple liquid.The wood is likely to sink in the 1st liquid(yellow) but float on the 2nd liquid(red).Explanation:
The arrangement of the liquids in the cylinder is determined by their densities. Water has a density of 1g/cm3 & that of the others are stated in the question already. Comparing the liquids densities now, we can easily identify the liquid with the lowest density to that of the highest. The liquids with greater densities will sink while those with lower ones wsill float. In this case, the yellow one has the least density of 0.46g/cm3,followed by the red one(0.91g/cm3),water of density 1.0g/cm3 & coming last, the purple liquid(1.62g/cm3)The wood has a density of 0.85g/cm3. This will make it denser than the 1st liquid(yellow) so will sink in it but is lower in density than the next liquid so will float on it.Hope you understand now. I'll appreciate getting brainliest from you if you liked the explanation.
The order of the liquids in the cylinder will be yellow liquid, followed by red liquid, water, and lastly purple liquid. The wood is likely to sink in the 1st liquid(yellow) but float in the 2nd liquid (red).
The densities of the liquids in the cylinder dictate how they are arranged. Water's density is 1g/cm³, and the other densities are previously mentioned in the question. Now that we can compare the liquid densities, we can quickly distinguish between the liquids based on density.
Higher-density liquids will sink, whilst lower-density liquids will float. The yellow liquid in this instance has the lowest density, 0.46 g/cm³, followed by the red liquid (0.9 g/cm³), water (1.0 g/cm³), and the purple liquid (1.6 g/cm³).
The density of the wood is 0.85g/cm³. Because of this, it will become denser than the first liquid (yellow), sink in it, but less dense than the second liquid, float on it.

Estimate the normal boiling temperature of propan-1-ol, C3H7OH, given that its vapour
pressure is 2701 Pa at 298 K and 9129 Pa at 318 K.
Based on the data provided, the normal boiling point of propan-1-ol is 93.7° C
What is the normal boiling point of a liquid?The normal boiling point of a liquid is the temperature at which the clvapor pressure of the liquid is equal to the atmospheric pressure.
The Clausius-Clapeyron Equation is used to determine the normal boiling point of liquids.
The Clausius-Clapeyron Equation is given as:
ln (P₁/P₂) = ΔHvap/R × (1/T₂ - 1/T₁)where
ΔHvap is in J/molR = 8.314 J/mol.KFrom the given data:
T1 = 298 K
T2 = 318 K
P1 = 2710 Pa
P2 = 9129
ΔHvap = ?
Substituting the values:
ln ln (P₁/P₂) = ΔHvap/R × (1/T₂ - 1/T₁)
ln (2710/9129) = ΔHvap/(8.314) × (1/318 - 1/298)
ΔHvap = 47843.57 J/molThen at P2 = 101325 Pa
Normal boiling point T₂ can be determined thus:
ln (2710/101325) = 47843.57/8.314 × ( 1/T₂ - 1/298)
T₂ = 366.7 K
T₂ = 93.7° C
Therefore, the normal boiling point of propan-1-ol is 93.7° C.

Differentiate bonding and non-bonding electrons?
Answer:
bonding electrons are when the electron have the same number and the connect,like valence electrons. Non-bonding electrons are only possible when an atom is unstable, no more than 2 electrons or if the atom is an isotope. bonding electron pairs occur in a covalent bond between two atoms. they include one electron from each atom in the covalent bond. non-bonding pairs do not take part in bonding. they are the left over electrons in the outter shell of the atom.

Plants lean towards the light because light is the energy source for plant growth. When a plant has a higher concentration of auxin on the shady side it causes that side to grow more so it can bend more towards the light. When this process happens, it's called positive phototropism.

Answer:
Cobalt
Explanation:
From the question given above, the following data were obtained:
Electronic configuration of element => 1s² 2s²2p⁶ 3s²3p⁶ 4s²3d⁷
Name of the Element =?
Next, we shall determine the number of electrons in the atom of the element. This can be obtained as follow:
Number of electron = 2 + 2 + 6 + 2 + 6 + 2 + 7
Number of electron = 27
Next, we shall determine the number protons in the atom of the element. This can be obtained as follow:
For a ground state element,
Number of Proton = number of Electron
Number of electrons = 27
Number of proton = Number of electron = 27
Number of protons = 27
Therefore, the number of protons in the atom of the element is 27
Next, we shall determine the atomic number of the element. This can be obtained as follow:
The atomic number of an element is simply the number of protons in the atom of the element. Mathematically,
Atomic number = proton number
Number of proton = 27
Finally, we shall determine the name of the element as follow:
Comparing the atomic number of the element (i.e 27) with those in the periodic table, the element is Cobalt since no two elements have the same atomic number.
