Answer:

D)

Explanation:

Ornithine and Citrulline are the amino acids which are metabolites in the urea cycle but not used as building blocks of proteins.

Ornithine is the most important reactant in urea cycle that is responsible for 80% of the excretion of nitrogen in the body. It even improves liver function.

Even Citrulline is not used in the building blocks of protein, Citrulline is mainly used to widen blood vessels and may play a role in muscle building.

A solution was indicated to have a pH value of 3.52. What is the (H+) of this solution?
san4es73 [151]

Answer:

A pH less than 7 indicates an acidic solution and a pH greater than 7 indicates a basic solution. Ultimately, the pH value indicates how much H+ has dissociated from molecules within a solution. The lower the pH value, the higher concentration of H+ ions in the solution and the stronger the acid.

If the reaction of 9.87 moles of potassium with excess hydrobromic acid produced a 79.8% yield of hydrogen gas, what was the act
Fed [463]
Answer is: 3,94 of hydrogen gas.
Chemical reaction: 2K + 2HBr → 2KBr + H₂.
n(K) = 9,87 mol.
n(H₂) = ?.
from reaction: n(K) : n(H₂) = 2 : 1.
9,87 mol : n(H₂) = 2 : 1
n(H₂) = 4,935 mol for 100% yield of reaction
n(H₂) = 4,935 · 0,798 = 3,94 mol for 78,9 % yield of reaction.

Solve the following question
Andrew [12]

Answer:

140. J/g*K

Explanation:

To find the specific heat capacity, you need to use the following equation:

Q = mcΔT

In this equation,

-----> Q = energy/heat (J)

-----> m = mass (g)

-----> c = specific heat (J/mole*K)

-----> ΔT = change in temperature (K)

Before you can use the equation above, you need to (1) convert kg to grams, then (2) convert grams to moles (via molar mass), and then (3) convert Celsius to Kelvin. The final answer should have 3 significant figures.

1.11 kg C₄H₈O₂ x 1,000 = 1110 g

Molar Mass (C₄H₈O₂): 4(12.01 g/mol) + 8(1.008 g/mol) + 2(16.00 g/mol)

Molar Mass (C₄H₈O₂): 88.104 g/mol

1110 grams C₄H₈O₂                1 mole
------------------------------  x  -------------------------  =  12.6 moles C₄H₈O₂
                                           88.104 grams

34.5 °C + 273 = 307.5 K

52.3 °C + 273 = 325.3 K

Q = mcΔT                                                                   <----- Equation

3.14 x 10⁴ J = (12.6 moles)c(325.3 K - 307.5 K)         <----- Insert values

3.14 x 10⁴ J = (12.6 moles)c(17.8)                                <----- Subtract

3.14 x 10⁴ J = (224.28)c                                 <----- Multiply 12.6 and 17.8

140. = c                                                         <----- Divide both sides by 224.28

**this answer may be slightly off due to using different molar masses/Kelvin conversions**
