Dr. Gupta says, No one must die of cancer except out of carelessness;
(1). First step is to stop all sugar intake, without sugar in your body, cancer cell would die a natural death.
(2). Second step is to blend a whole lemon fruit with a cup of hot water and drink it for about 1-3 months first thing before food and cancer would disappear, research by Maryland College of Medicine says, it's 1000 times better than chemotherapy.
(3). Third step is to drink 3 spoonfuls of organic coconut oil, morning and night and cancer would disappear, you can choose any of the two therapies after avoiding sugar. Ignorance is no excuse; I have been sharing this information for over 5 years. Let everyone around you know.God bless.

CLASS 10
Chemical Reactions and Equations Important Questions Class
Short Answer Type Questions[l] [2 Marks] -Year 2015
1.“We need to balance a skeltal chemical equation.” Give reason to justify the statement.
Answer. Skeltal chemical equation are unbalanced. We need to balance chemical equation because of law of conservation of mass. It states that ‘matter can neither be created nor be destroyed’. Therefore chemical equation must be balanced in each and every chemical reaction.
2.Giving an example list two information which make a chemical equation more useful (informative).
Answer.
(i) Physical state of reactants must be mentioned, e.g.
2H2 (g) + O2 (g)——– > 2H20 (l)
(ii) Condition in which reaction takes place are written on the arrow head, e.g.
chemical-reactions-and-equations-chapter-wise-important-questions-class-10-science-1
Consider the following chemical reaction
X + Barium chloride——–> Y + Sodium chloride
(White ppt)
(a) Identify ‘X’ and ‘Y’
(b) The type of reaction
(a) ‘X’ is Na2SO4 and Y is BaSO4.
(b) The type of reaction
Na2SO4 + BaCl2—–> BaSO4 + 2NaCl
(White ppt)
The reaction is precipitation reaction. It is also called double displacement reaction.
4. Name the reducing agent in the following reaction:
3MnO2 + 4Al———— > 3Mn + 2Al2O3
State which is more reactive, Mn or A1 and why?
Answer. ‘Al’ is reducing agent.
‘AT is more reactive than Mn v ‘Al’ displaces Mn from its oxide.
5.(i) Write a balanced chemical equation for process of photosynthesis.
(ii)When do desert plants take up carbon dioxide and perform photosynthesis?
Answer.
chemical-reactions-and-equations-chapter-wise-important-questions-class-10-science-2
(ii) In desert plants the stomata are open at night. They take CO2 at night and is stored in the form of acid and is used during day time for photosynthesis.

6.A Name the type of chemical reaction represented by the following equation:
chemical-reactions-and-equations-chapter-wise-important-questions-class-10-science-3
Answer.
(i) Combination reaction
(ii) Double displacement reaction (Precipitation reaction)
(iii) Decomposition reaction.
7. Write the chemical equation of the reaction in which the following changes have taken place with an example of each:
(i) Change in colour
(ii) Change in temperature
(iii) Formation of precipitate
Answer.
(i)Cu (s) + 2AgNO3 (aq)———–> Cu(NO3)2(aq) + 2Ag
The solution will become blue in colour and shiny silver metal will be deposited.
(ii) NaOH + HCl ———–> NaCl + H2O+ heat
The temperature will increase because heat will be evolved.
(iii) Pb(NO3)2 (aq) + 2KI (aq)———–> Pbl2 (s) + 2KNO3 (aq)
Yellow ppt
Yellow precipitate of Pbl2will be formed.
8.State the type of chemical reactions and chemical equations that take place in the following:
(i) Magnesium wire is burnt in air.

(b) (i) Molten NaCl is electrolytically decomposed to form sodium metal.
(ii) Aluminium metal is obtained by electric decomposition of bauxite ore mixed with cryolite.
(iii) Carbonate ores are thermally decomposed to give metal oxide which on reduction give metal.
