Enter an equation showing how this buffer neutralizes added aqueous base (csoh).
Answer:
Here, the buffer is NH₄Cl + NH₃
The strong base is added to the buffer solution, then the salt reacts with the base to form a weak base and water, which does not alter the pH
NH₄Cl + CsOH → NH₃ + CsCl + H₂O
NH₄⁺ + OH⁻ → NH₃ + H₂O
When we add strong acid to the buffer solution, the base NH₃ reacts with acid and forms salt, which does not alter the pH
NH₃ + H⁺ → NH₄⁺

Let a = 2i + 9j, b = –4i + 5j, c = i – 3j, and d = 14j where i and j are unit vectors. what is (a – b) – (2d – c) in terms of i and j? 5i – 27j 5i + 35j 7i – 27j 7i + 39j
By taking the difference between the given vectors, we will see that:
(a – b) – (2d – c) = 7i - 27j
How to operate with vectors?
Here we have the vectors:
a = 2i + 9j = (2, 9)b = –4i + 5j = (-4, 5)c = i – 3j = (1, -3)d = 14j = (0, 14)Where the right part is in component form.
And we want to find (a – b) – (2d – c), let's solve this in parts:
(a - b) = (2, 9) - (-4, 5) = (2 - (-4), 9 - 5) = (6, 4) = 6i + 4j
(2d - c) = 2*(0, 14) - (1, -3) = (-1, 28 - (-3)) = (-1, 31) = -i + 31j
Then:
(a – b) – (2d – c) = (6, 4) - (-1, 31) = (6 - (-1), 4 - 31) = (7, -27) = 7i - 27j

What is the molar solubility of agcl (ksp = 1.80 × 10⁻¹⁰) in 0.500 m nh₃? (kf of ag(nh₃)₂⁺ is 1.7 × 10⁷)
Based on the Ksp calculations, the molar solubility of AgCl in 0.500 M of NH₃ is equal to 2.77 × 10⁻² M.
How to determine the molar solubility.First of al, we would write the properly balanced chemical equation for this chemical reaction:
AgCl(s) ⇆ Ag⁺(aq)+ Cl⁻(aq) Ksp = 1.8 × 10⁻¹⁰
AgCl(s) + 2NH₃(aq) ⇆ Ag(NH₃)₂⁺(aq) Kf = 1. 7 × 10⁷
Given the following data:
Ksp of AgCl = 1.8 × 10⁻¹⁰Concentration of NH₃ = 0.500Kf of ag(nh₃)₂⁺ = 1.7 × 10⁷K = Ksp × Kf
K = 1. 80 × 10⁻¹⁰ × 1.7 × 10⁷
K = 3.06 × 10⁻³
Mathematically, the Ksp for the above chemical reaction is given by:
[tex]K=\frac{ [Ag(NH_3)_2^{+}][Cl]}{[NH_3]^2}\\\\3.06 \times 10^{-3}=\frac{[x][x]}{0.50^{2 }}\\\\3.06 \times 10^{-3}=\frac{x^2}{0.25}\\\\x^2 = 7.65\times 10^{-4}\\\\x=\sqrt{7.65\times 10^{-4}}[/tex]
x = 2.77 × 10⁻² M.

Identify which type of reaction the feature occurs in.
Answer:
independent reaction occurs in grana produces ATP, release oxygen and produce glucose. while light independent reactions occur in stroma, fixes carbon dioxide.Explanation: Photosynthesis is a process that converts light energy into chemical energy in a multi protein complex called a photo system. There are two types of photo systems are present in the thylakoid membrane: photo system II ( PSII) And photo system I (PSI). Each photo system captures the energy from sunlight by exciting electrons and these energized electrons are transported by “energy carrier” molecules, which power the light-independent reactions. light energy passes to two special chlorophyll a molecules in the reaction center. The light excites an electron from the chlorophyll a pair which passes to the primary electron acceptor and then replaced. In photo system II, the electron comes from the splitting of water, which releases oxygen as a waste product. In photo system I, the electron comes from the chloroplast electron transport chain.light-independent reactions also called calvin cylce do not use light takes place at day or night for functioning they require the products of the light dependent reactions. The light-independent molecules depend on the ATP and NADPH, to form new carbohydrate molecules. After energy is transferred, the energy carrier molecules return to the light dependent reactions to take more energized electrons. but several enzymes of the light-independent reactions are activated by light
What are the coefficients needed to balance this chemical reaction to show that matter is conserved? fe + cl2 → fecl3
Let a, b, and c be the coefficients in the balanced reaction:
a Fe + b Cl₂ → c FeCl₃
Count the atoms that show up among the reactants and products. They should be equal on both sides:
Fe : a = c
Cl : 2b = 3c
Let c = 2. Then a = 2 and 2b = 6, so b = 3.
Then the balanced reaction is
2 Fe + 3 Cl₂ → 2 FeCl₃
