In a chemical reaction the reactants contain 385 KJ of chemical energy and the products contain 366 KJ of chemical energy.?
In this chemical reaction, the reactants have a higher chemical energy (385 kJ) compared to the products (366 kJ). This indicates that the reaction releases energy, specifically 19 kJ, which is the difference between the two energy levels. This energy release suggests that the reaction is exothermic, meaning it generates heat as the reactants transform into products.

How many Kilojoules in a 100g of sugar?
A 5 ml teaspoon (4 g) of sugar contains 68 kilojoules (kJ).
How many kcals are in 18 grams of protein?
Protein contains approximately 4 kilocalories (kcals) per gram. Therefore, to find the total calories in 18 grams of protein, you would multiply 18 by 4, resulting in 72 kcals. Thus, 18 grams of protein contains about 72 kcals.
In a chemical reaction the reactants contain 385 kJ of chemical energy and the products contain 366 kJ of chemical energy. In order for energy to be conserved what must happen?
In a chemical reaction, energy must be conserved, so the difference in energy between the reactants and products must be accounted for. Since the reactants contain 385 kJ and the products contain 366 kJ, there is a net release of 19 kJ of energy. This energy is typically released as heat or light into the surroundings, ensuring that the total energy of the system and its environment remains constant.

In a chemical reaction the reactants contain 385 kJ of chemical energy and the products contain 366 kJ of chemical energy?
In this chemical reaction, the reactants have 385 kJ of chemical energy, while the products have only 366 kJ. This indicates that the reaction is exothermic, as it releases energy in the form of heat, resulting in a net loss of 19 kJ of energy. The difference represents the energy released to the surroundings during the reaction.
Are protein fats and carbohydrates are the only nutrients that cause energy?
Yes it is. Proteins and carbs have 4 kcals/gram and fats have 9 kcals/gram.
How much of energy one gram of fat?
1 gram of fat provides 9 kcals......and 1 gram of protein/carbs provide 4 kcals...
The reactants contain 385 kJ of chemical energy and the products contain 366 kJ of chemical energy in order for energy to be conserved what must happen?
In order for energy to be conserved during a chemical reaction where the reactants contain 385 kJ of chemical energy and the products contain 366 kJ, the difference of 19 kJ must be released to the surroundings. This energy is typically lost as heat, light, or sound, indicating that the reaction is exothermic. The law of conservation of energy states that energy cannot be created or destroyed, only transformed, so the released energy accounts for the discrepancy between the energy of reactants and products.
