What does kJ measure?
Energy.
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.
How much energy must be transfered by heat to the engines surroundings if 2.5 kj is transfered by heat to the engine with 8.5 percent efficciency?
There are two possible answers to this question - depending on how you read it: If 2.5 kJ is converted to work but that only represents 8.5% efficiency, then the heat transferred to the surroundings will be 2.5(1-0.85)/0.85 = 26.9 kJ On the other hand, if 2.5 kJ is the total energy coming in and only 8.5% of it is converted to work, then the other 91.5% is lost to the surroundings: 2.5(1-0.085) = 2.2875 kJ
In chemistry what does KJ mean?
That is an abbreviation for a kilojoules, a metric measure of energy.
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.
A system gives off 196 kJ of heat to the surroundings and the surroundings do 4.20 x 10 2 kJ of work on the system What is the change in internal energy of the system?

What is the lattice energy for potassium bromide?
The lattice energy for KCl is 715 kJ mol-1.
For the chemical reaction H2 CO2--H20 Co the energy contained in the reactants is 352 kj and the energy contained in the products is 394 kj assuming 1 mol of each substance is present is this true?
No, this is not true. The energy contained in the reactants is 352 kJ, and the energy contained in the products is 394 kJ, suggesting that energy was released during the reaction. However, energy should be conserved in a chemical reaction, so the total energy in the products should be equal to the total energy in the reactants.
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.

What is a kj?
"KJ" could refer to kilojoule, a unit of energy commonly used in nutrition to measure the energy content of food. It is equivalent to 1,000 joules.
