2ZnS(s)+3O2(g) -> 2Zns(s) + 2SO3(g)
the above given equation is unbalanced as it contains 4 moles of sulphur in the output but in the input there are only two aoms of sulphur so to balance the equation we will write the equation as given under
balanced equation is
2ZnS(s)+3O2(g) -> 2Zn(s) + 2SO3(g)
In words:
When 2 moles of solid zinc sulfide reacts with 3 moles of oxygen gas gives 2 moles of solid zinc and 2 moles of sulphur trioxide gas.
Answer:
Hydrogen's location is related to it's electron configuration not it's properties.
Even though hydrogen is gas it can be used as fuel in automobile because it is flammable
Answer: Energy is being absorbed as the reaction proceeds
Explanation:
Endergonic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and 
for the reaction comes out to be positive.
Exergonic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and for the reaction comes out to be negative.
Thus an endergonic reaction refers to a chemical reaction in which Energy is being absorbed as the reaction proceeds.
Answer:
Electromechanical waves are defined as the waves which resulting from the interaction of magnetic fields, and oscillating electric. Some examples of these electromechanical wave are infrared, microwave, ultraviolet, visible, etc.
When these waves are arranged in the order of increasing wavelength then it's called an electromagnetic spectrum, and
spectral regions in order of increasing wavelength, we will get is:
Ultraviolet<visible<infrared<microwave.
