Greetings,
In this situation, the chemical reaction taking place is:

Thus, based on the provided data, the theoretical yield of C can be determined as:

Additionally, taking into account the principle of conservation of mass, the mass prior to the reaction is equal to the mass following the reaction, hence, the mass of B that was utilized amounts to:

Best regards.
The classification is
disaccharide.
<span>Lactose qualifies as a disaccharide since it's made up of two monosaccharides, which are simple sugars (glucose and galactose). Disaccharides constitute a subgroup of carbohydrates, and besides lactose, other common examples include sucrose and maltose.</span>
A total of 1.505×10^23 lead atoms
In the lungs, the volume of lead equals the total lung volume, which is 5.60L
1 mole corresponds to 22.4L
Thus, 5.6L of lead converts to 5.6/22.4 = 0.25 moles
According to Avogadro's law
1 mole of lead contains 6.02×10^23 lead atoms
Thus, 0.25 moles of lead equates to 0.25×6.02×10^23 = 1.505×10^23 lead atoms
Although I may not be the smartest, I can definitely answer.
This represents a chemical change because the substances' chemical identities were altered. The fizzing was a clear sign, and the temperature increase was another indicator of the reaction.
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.
