What else can I help you with?
Does a change in energy occur in matter in making natural glue?
yes
What happens when a reaction that is endothermic and results in an overall increase in entropy occurs?
When an endothermic reaction occurs and there is an overall increase in entropy, it means that energy is absorbed from the surroundings and the disorder or randomness of the system increases.
Why do some pair of ions in solution form precipitates?
When two oppositely charged ions in solution react, they can form an insoluble compound known as a precipitate. This occurs when the product of the reaction has a low solubility in the solvent, causing it to come out of solution as a solid. The formation of precipitates is used in laboratory settings to identify and remove specific ions from solution.
How do you calculate the heat of neutralization for a chemical reaction?
The heat of neutralization for a chemical reaction can be calculated by measuring the temperature change that occurs when an acid and a base react to form water and a salt. This change in temperature is then used in the formula Q mcT, where Q is the heat energy, m is the mass of the solution, c is the specific heat capacity of the solution, and T is the temperature change.
When an exothermic reaction occurs in a water solution what happens to the temperature of the solution?
The temperature rises. An "exothermic" reaction releases heat energy in the process.
Is all the energy transferred during an energy change always useful?
No, not all energy transferred during an energy change is always useful. Some energy may be lost as heat or sound, decreasing the overall efficiency of the energy transformation. This is known as energy wastage, and it occurs in many natural and human-made processes.
When energy removed from a substance what chANGE OCCUR?
When energy is removed from a gas, condensation occurs. When energy is removed from a liquid, freezing occurs.
What change in form of energy occurs in a stereo speaker?
Electric Energy to Sound Energy.

The energy change that occurs when an atom gains electrons is called the
What energy change occurs when one of light bulbs is turn on?

What is the energy change that occurs when an atom loses electrons called?
ionization energy
What is a plants cells source of energy?
Overall equation for the type of photosynthesis that occurs in plants.
Describe the energy change when magneium burns?
Oxidation occurs
What type of energy change occurs cellular respiration?
f4g
Is a precipitate a phsical change?
Yes, a precipitate is a physical change. It occurs when two solutions react to form a solid that settles out of the solution. This is a reversible change as the solid can be redissolved back into the solution.
Does a change in energy occur in matter in making natural glue?
yes
What happens when a reaction that is endothermic and results in an overall increase in entropy occurs?
When an endothermic reaction occurs and there is an overall increase in entropy, it means that energy is absorbed from the surroundings and the disorder or randomness of the system increases.
