Answer:
Be,Mg,Ca,Sr,Ba.Ra[down the group electronegativity is decreasing]
Explanation:
During the breakdown of fatty acids, not all acetyl CoA enters the citric acid cycle, and your body converts some acetyl CoA to ketone bodies.
Acids are molecules or ions that can donate protons, known as Bronsted-Lowry acids, or form covalent bonds with electron pairs, known as Lewis acids. The first category of acids is proton donors or Brønsted-Lowry acids.
Acids are used as catalysts in technical and organic chemistry. For example, sulfuric acid is used in very large amounts in the alkylation process for producing gasoline. Some acids, such as sulfuric acid, phosphoric acid, and hydrochloric acid, also cause dehydration and condensation reactions. Although about 500 amino acids have been identified in nature, only 20 amino acids make up the proteins found in the human body.

Answer:
The answer to your question is 16.7 g of Cr(CH₃COO)₃
Explanation:
Data
Concentration = 0.243 M
Volume = 300 ml
mass of Chromium (III) acetate = ?
Process
1.- Write the formula of the compound
Cr(CH₃COO)₃
2.- Calculate the molar mass of the compound
Cr(CH₃COO)₃ = 52 + (6 x 12) + (9 x 1) + (6 x 16)
= 52 + 72 + 9 + 96
= 229 g
3.- Determine the number of moles
Molarity = moles /volume
Moles = Molarity x volume
Moles = 0.243 x 0.300
Moles = 0.0729
4.- Calculate the grams of chromium (III) acetate
229 g ------------------ 1 mol
x ----------------- 0.0729 mol
x = (0.0729 x 229) /1
x = 16.7 g of Cr(CH₃COO)₃
Answer:
T = 154 K
Explanation:
Given data:
Number of moles of Cl₂ = 0.07 mol
Pressure = 1.18 atm
Volume = 750 mL
Temperature = ?
Solution:
The given problem will be solve by using general gas equation, which is,
PV = nRT
R = general gas constant (0.0821 atm.L/mol.K)
Now we will convert the mL to L.
Volume = 750 mL × 1 L/1000 mL
Volume = 0.75 L
Now we will put the values in formula.
T = PV/nR
T = 1.18 atm × 0.75 L / 0.07 mol ×0.0821 atm.L/mol.K
T = 0.885/0.00575 /K
T = 154 K
