What else can I help you with?
Can compounds be created by chemical reactions?
Yes, compounds can be created by chemical reaction. They can also be destroyed by chemical reaction.
Could the change in the pH paper itself be a reaction Support your answer?
The substances contained in the pH paper react with the substance to be tested; and this is a chemical reaction.
What is chemical rection?
A chemical reaction is a process where one or more substances (reactants) are transformed into different substances (products) by breaking and forming chemical bonds. This process involves the rearrangement of atoms and the breaking or forming of chemical bonds.
Is movement an exergonic reaction?
Movement is not considered an exergonic reaction. Exergonic reactions typically refer to chemical reactions that release energy, while movement in living organisms is driven by processes such as muscle contraction and nerve impulses rather than by a specific chemical reaction.
Why are reactants important in chemistry?
A chemical reaction without reactants is not possible.
Is petrol in a car a chemical reaction?
Yes, using petrol (gasoline) in a car to produce movement is a chemical reaction.
Could oxygen be produced from a chemical reaction if none of the reactants contained oxygen atoms?
No.
Can compounds be created by chemical reactions?
Yes, compounds can be created by chemical reaction. They can also be destroyed by chemical reaction.
Is it possible for the change in enthalpy, represented as H, to have a negative value in a chemical reaction?
Yes, it is possible for the change in enthalpy (H) to have a negative value in a chemical reaction, indicating that the reaction releases heat energy.
Could the change in the pH paper itself be a reaction Support your answer?
The substances contained in the pH paper react with the substance to be tested; and this is a chemical reaction.
Can an electric can opener cause a chemical reaction on a tin can?
It is not possible.
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.

Would NaHCO3 react with NaCl?
Any chemical reaction is possible.
Why are reactants important in chemistry?
A chemical reaction without reactants is not possible.
Chemical energy is contained in what?
Chemical energy is contained in the bonds between atoms within molecules. When these bonds are broken or rearranged during a chemical reaction, energy is released or absorbed. Examples include the energy stored in food molecules like glucose and in fossil fuels like gasoline.
