Answer:
The amount of charge on a single proton is equal to the amount of charge possessed by a single electron. A proton and an electron have an equal amount but an opposite type of charge. Thus, if an atom contains equal numbers of protons and electrons, the atom is described as being electrically neutral.
A dust particle with mass of 0.050 and a charge
For a balance chemical equation:
The number of atoms of a molecule should remain conserved that is total number of atom of a molecule in reactant side should equal to the number of atoms of a molecule in the product side.
Here also the number of atoms of an element should remain conserved on both sides, So the answer is option B.
That is
B) 3CuCl₂ + 2Al ---> 2AlCl₃ + 3Cu
Here the number of atoms of Cu, Cl and Al are equal in both side , reactant as well as product.
Answer:
Option C, developmental view point
Explanation:
A person with preservationist viewpoint will think of only preserving the natural resources and the environment. While a person with a conservationist viewpoint will think of conserving the landscape, architecture, heritage, culture, buildings, rituals, etc.
However, a person with developmental viewpoint will think of developing resources at ease. He/She will prioritize development and comfort of customer above all.
Hence, option C is correct
