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.

Does The Law of Conservation of Matter states that The products of a reaction will contain the same amount ofmatter than the reactants had before a reaction.?
Yes, the Law of Conservation of Matter states that the total amount of matter remains constant in a closed system during a chemical reaction. This means that the mass of the reactants before the reaction is equal to the mass of the products after the reaction. Thus, the products will contain the same amount of matter as the reactants had.
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.
Can atoms that are not in the reactants end up in the products of a chemical reaction?
Yes, atoms that are not present in the reactants can end up in the products of a chemical reaction if they are introduced during the reaction. This can occur through several means, such as the use of catalysts, the presence of solvent molecules, or the incorporation of additional reactants. For example, in combustion reactions, oxygen from the air is added to the reactants, resulting in products that contain atoms not originally present in the starting materials. Thus, the final composition of the products can include atoms from outside the initial reactants.
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.
How do chemical reaction change substances?
After a chemical reaction, some of the bonds have been broken, and some new bonds have been formed. So, that's how a substance is changed after the reaction.
How do the reactants of a chemical reaction differ from the products of the same reaction?
Reactants are the starting materials that are present at the beginning of a chemical reaction, while products are the substances that are formed as a result of the reaction. Reactants undergo a chemical change to form products during the reaction.
What information does chemical information contain?
the reactants and products. reactants=what compounds or elements are reacting products= what compounds or elements are produced from the reaction
What must be true about the properties of the reactants and the properties of the products in a chemical reaction?
The reactants and the products must contain the same numbers of the same types of atoms, that is, atoms with the same atomic number, and either the products must contain at least one type of chemical bond distinct from any chemical bond in the reactants or the reactants must contain at least one type of chemical bond not found in the products.
When looking at a chemical reaction how do you know what the reactants and products are?
In an equation the reactants are the on the left of the arrow, and the products are on the right. For example if you had the following equation: 2H2 + O2 => 2H2O 2H and O will be the reactants and H2O is the product.
How do chemical reaction change substances?
After a chemical reaction, some of the bonds have been broken, and some new bonds have been formed. So, that's how a substance is changed after the reaction.
Why are the properties of reactants different from that of products?
The products of a chemical reaction have different properties than the reactant because they underwent a chemical change by definition of a chemical reaction. The products are new combinations atoms forming different molecules.
Chemical equation has how many parts?
Most chemical equations have a few standard elements (no pun intended). There are the reactants on the left side, the arrow showing the direction of the reaction, and the products on the right side. Sometimes, properties of the reaction such as the enthalpy is shown after the equation. Often times, especially in organic chemistry, there will be other compounds or parameters written above and/or below the reaction arrow to indicate what chemicals were needed to make the reaction occur.
Do the bonds of the products contain more or less energy than the original compounds?
In a chemical reaction, the bonds of the products may contain more or less energy than the original compounds, depending on the specific reaction and the energy required to break and form bonds. If the reaction is exothermic, the products will have lower energy bonds than the reactants, whereas in an endothermic reaction, the products will have higher energy bonds.
What does a chemical equation have?
It contain the chemical formula of the specified compounds (reactants and final products), it contains the chemical proportions of a compound (coefficients).
The only reactants in a reaction were Zn and HCI. What does the law of conservation of matter say about the products?
The law of conservation of matter states that matter cannot be created or destroyed in a chemical reaction. Therefore, the total mass of the products formed from the reaction between Zn and HCl must be equal to the total mass of the reactants.
If the products of a reaction are NaCl and H2O what does the law of conservation of mass reveal about the reactants in the reaction?
The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction. Therefore, for the products NaCl and H2O to be formed, the reactants must contain the same amount of sodium, chlorine, and hydrogen atoms as found in NaCl and H2O, respectively.
If the only reactions of a reaction were Zn and HCl what does the law of conservation of mass say about the products?
the products will contain only Zn,H, and Cl. apex
