What else can I help you with?
If two substances react spontaneously and energy is released as a product the reaction is?
This is a spontaneous reaction.
What describes a non spontaneous reaction?
Non spontaneous means that when you say in chemical terms, mix two different substances together, they don't react to form something new. A counter example to this is baking soda and vinegar. If you mix them together, they will spontaneously react to produce carbon dioxide. Non spontaneous processes require some form of energy input in order to all the reaction to occur.
How is thermal energy involed in chemical reactions?
Thermal energy is involved in chemical reactions by providing the necessary activation energy for the reaction to occur. Increasing the temperature increases the kinetic energy of the molecules, making them more likely to collide with enough energy to react. Additionally, some reactions are exothermic, releasing thermal energy as a byproduct.
How do things react in science?
In science, reactions occur based on the interactions between different substances or forces. These reactions can result in changes such as chemical reactions, physical changes, or the release of energy. Understanding these reactions is a key aspect of scientific study and can help explain the behavior of matter and energy in the natural world.
When Could A High Temperature Make A Reaction That Was Nonspontaneous At Low Temperature Spontaneous?
A high temperature can make a nonspontaneous reaction spontaneous by providing enough energy to overcome the activation energy barrier, allowing the reaction to proceed. At low temperatures, the kinetic energy of the molecules may not be sufficient for them to react, but increasing the temperature can provide the necessary energy for the reaction to occur spontaneously.
In what way is energy changed by reactions in a chloroplast?
it's react towards light. it transforms light energy to a chemical energy of photosynthesis. So this light energy is trapped by chlorophyll molecules and converted to chemical energy. dB!
When two chemicals react what happens to their internal energy?
When two chemicals react, their internal energy changes as a result of the breaking and forming of chemical bonds. Energy is either absorbed or released during the reaction, depending on whether it is endothermic (absorbing energy) or exothermic (releasing energy). This change in internal energy can lead to variations in temperature and can drive the reaction forward or backward. Overall, the total energy is conserved, in accordance with the law of conservation of energy.
Why iron does not react with mercury to form amalgam?
Iron does not react with mercury to form an amalgam because iron is not chemically reactive enough in this case. The reaction between iron and mercury requires a substantial energy input to overcome the activation energy barrier, which is not easily achieved at room temperature. This results in the lack of a spontaneous reaction between the two elements.
What process or chemical reactions go on inside a cell?
When two molecules react within a cell, their atoms are rearranged. This releases or consumes energy.
Which is a general chemical equation for an endothermic double-replacement reaction?
A general chemical equation for an endothermic double-replacement reaction can be represented as: [ A + B \rightarrow C + D + \text{heat} ] In this case, compounds A and B react to form new compounds C and D, absorbing heat in the process. This indicates that energy is required for the reaction to proceed, characteristic of endothermic reactions.
Enzymes speed up chemical reactions by?
lowering the activation energy required for the reaction to proceed, thereby allowing the reaction to occur more quickly. This is achieved by binding to the reactant molecules and changing their conformation, making it easier for them to react and form products.
How do enyzme speed up chemical reactions?
Enzymes act as catalysts; they lower the activation energy of a reaction thus allowing more of the involved particles to react.
