x is greater than or equal to 56Step-by-step explanation: He requires at least 56 additional cans. Hence, x should be a minimum of 56.
Respuesta:
D
Explicación:
Utilizamos la relación de moles para calcular la presión parcial. El número total de moles es 0.2 + 0.2 + 0.1 = 0.5 moles
Ahora, sabemos que la fracción molar del gas argón es 0.2/0.5
La presión parcial se determina así. Para calcular esto, simplemente multiplicamos el número de moles por la presión total.
0.2/0.5 * 5 = 1.0/0.5 = 2.00atm

Answer:
Benzoyl Chloride
Explanation:
Friedel-Craft Acylation is a reaction used to incorporate electrophiles (especially carbonyl groups) into the double bonds of aromatic compounds.
This scenario involves synthesizing benzophenone using benzene and benzoyl chloride.
Mechanism:
Step 1: Initially, benzoyl chloride reacts with a Lewis acid to create an electrophile known as oxo(phenyl)methylium.
Step 2: The second stage involves benzene participating in an electrophilic substitution reaction, where the electrophile is added.
Step 3: Finally, the aromatic nature of benzene is restored by releasing a proton.
The soccer field's length is 3.94 × 10^2 in.
Length = 100 m × (39.37 in/1 m) = 394 in = 3.94 × 10^2 in
Response:
3:1
Explanation:
Stearic acid - C18H36O2
Fructose- C6H12O6
The energy content in food is largely proportional to the carbon content. This can be expressed as:
C18/C6 = 3 or 3:1
This illustrates why fats and oils serve as the primary energy source for the body rather than carbohydrates. This is because fats and oils contain significantly higher amounts of carbon compared to carbohydrates.
