Answer:
Energy is transferred from one object to another when a reaction takes place.
Explanation:
Energy comes in many forms and can be transferred from one object to another as heat, light, or motion, to name a few.
The answer could be It is a well known fact that energy can neither be created and nor be destroyed but can be transformed from one form to another.
Now talking about your example in a typical light bulb electrical energy is converted into light energy and heat energy. Now when the electric current flows through the conductor/filament in the light bulb,this would cause vibrations and the free ions are more likely to go to an higher energy level,and when the ions come back to their original state,the difference in the two energy levels is usually emitted as a photon,thus light energy is obtained and the heat energy is the energy dissipated as a result of flow of electricity through the conductor.
Anything that gets transformed into light energy or in better words ElectroMagnetic Energy would be a result of this.
Number one would be Decades
This problem has two parts; the first one asking for the concentration of NaBr given both its mass and volume and the second one asking for its volume given both mass and concentration. The answers turn out to be 0.158 M and 211 mL.
<h3>Molarity</h3>
In chemistry, the use of units of concentration depends on both the substances to analyze and their amounts. In such a way, for molarity, one needs the following relationship between the moles of solute and volume of solution:
Thus, for the first part of the problem we first calculate the moles in 2.60 g of NaBr via its molar mass:
Next, we convert the 160. mL to L by dividing by 1000 in order to obtain 0.160 L to subsequently calculate the molarity:
Next, since the moles remain the same and for the second part we are asked for the volume given the concentration, one can solve for the volume so as to obtain:
That in milliliters turns out to be:
