1. How do the different stages of development affect a person’s ability to react to situations? Explain briefly.
D. Not all mixtures are heterogeneous
First, write the equation:
Cu + O2 -> CuO
Now, balance:
2 Cu + O2 -> 2 CuO
The atoms on the products side are bonded into different molecules from the atoms on the reactants side is the chemical changes occured.
<u>Explanation:</u>
- The reaction commences when the compounds on the reactant side are ready to react to give the product.
- The reaction initiated by the transfer of electrons and molecules from the reactants to give the combined product of both the reactants.
- It is a process on which there will be rearrangement in the structure of molecules of a substance from its physical for more chemical form.
- In the above picture it shown that the red molecules combined with the white molecules additionally and changed the structure.
Current is the rate at which electric charge flows past a point in a circuit. In other words, current is the rate of flow of electric charge. Voltage, also called electromotive force, is the potential difference in charge between two points in an electrical field. ... Current is the effect (voltage being the cause).
