500. ml of a solution containing 1. 5 m nh3(aq) is mixed with 500. ml of a solution containing 0. 50m of hcl(aq). what is the ph of the final solution? (kb(nh3) = 1. 8 x 10-5)
The pH of the solution is determined by the hydrogen ion concentration. The pH of the solution with 1.5 M ammonia and 0.50 M hydrochloric acid is 8.77.
What is pH?The potential of the hydrogen ion in the solution is called pH which determines the basicity and acidity of the solution.
Given,
The molar concentration of 500 mL ammonia = 1.5 M
The molar concentration of 500 mL hydrochloric acid = 0.50 M
Kb (NH₃) = 1. 8 x 10⁻⁵
First, pOH is calculated as,
pOH = pKb + log [NH₃][HCl]
= - log 1. 8 x 10⁻⁵ + log [1.5][0.50]
= - log 1. 8 x 10⁻⁵ + log [3]
= 4.744 + 0.477
= 5.221
Now, pH is calculated from pOH as,
pH = 14 - pOH
= 14 - 5.221
= 8.77
Therefore, 8.77 is the pH.

While working in a pharmaceutical laboratory, you need to prepare 1.50 L of a 2.20-M NaCl solution. What mass of NaCl would be required to prepare this solution
193 grams of NaCl are needed to make 1.50 L of a 2.20-M NaCl solution.
Calculation of the mass of NaCl required:
The only thing we need to know is that a solution's molarity informs us of the exact amount of moles of solute that are contained in 1 L of a solution.
In this situation, a NaCl (sodium chloride) solution with a 2.20-M concentration will have 2.20 moles of the solute (sodium chloride) in every 1 L of the solution.
The solution's molarity of 2.20 M requires that every 1 L of this solution include 2.20 moles of sodium chloride, which implies that every 1.50 L of this solution needs to contain
[tex]1.5 L solution .\frac{2.20 moles NaCl}{1L solution} = 3.30 moles NaCl[/tex]

What is the theoretical yield (mass of Al2O3 formed) for this reaction?
(answer is not 204)
Answer:
102 g Al₂O₃
Explanation:
The theoretical yield is the mass of product calculated via the molar masses and balanced chemical equation.
The limiting reagent is the reactant that is completely reacted before the other reactant(s) are used up. Since Al produces the smaller amount of product, it appears that Al is the limiting reactant. You can only make as much product as the limiting reactant allows. As such, the theoretical yield is 102 grams Al₂O₃.

The numbers are written as a product:
a×10ⁿ
where:
a is a real number greater than or equal to 1 and less than 10, to which a decimal point is added after the first digit if it is a non-integer number.n is an integer, which is called an exponent or an order of magnitude. Represents the number of times the comma is shifted. It is always an integer, positive if it is shifted to the left, negative if it is shifted to the right.Subtraction in scientific notationYou want to subtract two numbers in scientific notation. It should be noted that when the numbers to be added do not have the same base 10 exponent, the base 10 power with the highest exponent must be found. In this case, the highest exponent is 5.
Then all the values are expressed as a function of the base 10 exponent with the highest exponent. In this case: 5.00×10⁴=0.500×10⁵
Taking the quantities to the same exponent, all you have to do is subtract what was previously called the number "a". In this case:

Which best explains why the trend in noble gas boiling points increases down the group?.
The atoms become larger, the intermolecular forces between the atoms become stronger and more energy is needed to overcome these forces. Hence, the boiling point of noble gases increases down the group.
What are noble gases?
Group 18 of the modern periodic table consists of noble gases. Helium, neon, argon, krypton, xenon, and radon are noble gases. These gases are monoatomic and chemically inert under normal conditions and because of this they are also called inert gases. These gases are present in very small quantities in the atmosphere, and so they are also called rare gases.Trends in Physical Properties of Noble Gases:
Atomic Radii (Atomic size): As we move down the group from helium to radon the atomic size of Noble Gasses keeps on increasing. This is because when going down the group, the number of occupied shells with valence electrons increases.Boiling and Melting Points: As we move down the group, the boiling and melting point of the Noble Gasses increases due to the following reason:When moving down in the group, the atomic radius increases which results in the formation of a strong Van Der Waals force of attraction between the atoms.As to overcome the interatomic force of attraction which becomes stronger, it also requires more energy during melting and boiling.Density: All elements of group 18 have low densities. When going down the group, density increases as the atomic mass keeps on increasing.Ionization Energy: In the periodic table, As we move down the group the first ionization energy keeps on decreasing.Ionization Potential: When going down the group, the atomic radii increases which increases the attractive force and ultimately results in the increase of polarity and decrease in the ionization potential. This is because the larger atom of the group in the valence electrons are held together less tightly by the atom as they are situated far away from the nucleus.To learn more about trends in noble gases:

P1V1 / n1T1 = P2V2 / n2T2...P is constant.T is constant.. so

since n = mass / mw
V1 / (mass 1 / mw) = V2 / (mass 2 / mw)
and since molecular mass = constant
V1 / mass 1 = V2 / mass 2
mass 2 = V2 x mass 1 / V1 = 2.90L x 2.00 g / 2.00 L = 2.9 g

Urine color is the most effective method for measuring hydration status before and after exercise
Urine color is yellow color from a pigment called urochrome or urobilin. Darker pee contains less fluid, whereas lighter urine is more diluted. Dehydration may be indicated by very black urine. Don't worry if your urine doesn't match the color scheme.
Normal urine color is a pale yellow, however light amber is also acceptable. If your pee appears dark amber, you may be dehydrated and should drink additional water to compensate.

299.7 moles of electrons are required to produce 99. 9 g of aluminum metal from a sample of molten aluminum fluoride.
Calculation,
The production of aluminium metal is given as,
[tex]Al^{+3} + 3e^{-}[/tex]→ [tex]Al[/tex]
The 3 moles of electrons require to produce 1 gm of atom of aluminium ( weight = 27 ) solution fluoride.
The number of moles of electrons are required to produce 99. 9 g of aluminum metal from a sample of molten aluminum fluoride = 3mol×99.9g/1g
The number of moles of electrons are required to produce 99. 9 g of aluminum metal from a sample of molten aluminum fluoride = 299.7 moles

What is the molarity of nickel ii chloride at 0.500 liters with 1 mole of nickel ii chloride solution?
Answer:
Molarity = 2 M
Explanation:
The molarity can be found using the molarity ratio:
Molarity = moles / volume (L)
You can plug the given moles and volume into the ratio and solve.
Molarity = moles / volume
Molarity = 1 mole / 0.500 L
Molarity = 2 M
