According to kinetic theory of energy, the intermolecular spaces between molecules of solids are very less and so have strong intermolecular force and thats why the molecules do not actually move and just vibrate which is cause that they have definite shape and volume

NaHCO₃ symbolises baking soda which is used as detergent for clothes, vessels, and also households it can be also used as toothpaste and makes teeth white used as a polishing materials for metals,etc.

By inhaling air which contains more oxygen and less carbon dioxide we respirate and this carbon is used many places in our body for making some bonds but their more amount can also harm us but as considered to carbon each and every being contains carbon in one or the other way

First of all, magnesium is a metal so it would lose electrons as it has less than 4valence electrons as it has atomic no. 12 so its electronic configuration would be (2,8,2) so there are 2valence electrons and so it would lose 2electrons to attain stability

There can be only 2electrons utmost in this shell hydrogen have one electron in this shell helium have 2electrons in this shell let the no. Of shells be n No. Of electrons = 2n² here take example of shell no. 3 no. Of electrons in this shell = 2 (3)² = 2 * 9 = … Read more

An atom consists of three fundamental particles electrons, protons, neutrons neutrons and protons make up the nucleus

To explain this I can give just examples
a strong acid such as HCl has ph of 0 to 1 at the mole value of 1dm^-3

a strong alkaline like NaOH will have ph of 13 to 14 at the same mole as that of HCl

Excretion is very necessary for our body as all the wastes inside the body are excreted and also the extra things are excreted also osmoregualtion is maintained

You its the rite answer but none has given the name for the formulae its ammonium hydroxide ( NH_4^OH) which is a basic solution

By burning fossil fuels a lot of problems get arise when we burn fossil fuels they release many effluents that are harmful for the environment such as sulphur dioxide , carbon monoxide ,etc. Also by burning these at a rapid rate they will get exhausted and it would be a great loss for human lives … Read more

The solution to water pollution is firstly trying yourself not to harm water resources from your side we can then plan projects that are not harming water resources such as industrialists should co operate and should try to throw garbage to a isolated place so that it would be not harmful to environment there should … Read more

No air is not a conductor but an insulator the electrons in air molecules are very tightly bound to their respective molecules in the form of covalent bonds. As a result it takes a lot of energy to rip the electrons free so that they can take part in an electric current. IN general the … Read more

Plants need sap as in a plant cell there is a large vacuole which contains cell sap and as vacuole is a larger content of cell and will not contain its composition it would effect the cell growth

Its copper as it is less reactive than hydrogen and a less reactive metal can't displace the higher reactive metal from its chloride and all other are more reactive than hydrogen magnesium reacts with hydrogen chloride to form magnesium chloride and displaces hydrogen aluminium forms aluminium chloride and displaces hydrogen and iron reacts to form … Read more

Immortality of souls means that the souls which do not have life and are dead which is by the way a wrong fact because the souls never die but it is the body which die.

It has 118 elements characterised all the elements having same no. Of valence electrons are placed in a vertical columns called groups. There are 18 groups. All the elements in one group have same chemical properties. All the elements are arranged in order of their increasing atomic no. In horizontal columns called periods. There are … Read more
