Answer: B) FALSE Explanation: Nitrogen is found as a diatomic molecule (N2) in nature. There is a triple bond between the two nitrogen atoms.   The triple bond is pretty strong. Therefore, it needs a lot of energy to break those bonds and participate in a reaction. So nitrogen is commonly referred to as and used as an inert gas (high abundance & low cost.) However, it’s not truly inert like most noble gases. Nitrogen does react if the conditions are met. But those conditions are not exactly mild, but are not as extreme as for noble gases.   It forms nitric oxide and nitrogen dioxide with oxygen, ammonia with hydrogen, and nitrogen sulfide with sulfur.

Answer: D) None Explanation: Amount = 80001+51002   = 8000 x 21/20 x 21/20    = Rs. 8820

Answer: A) 8, 72 yrs Explanation: Let the present ages be K,M Given K/M = 4/5 5K - 4M = 0 ......(1) Also given that, M - (K + 5) = 3 M - K = 8 .........(2) Then, by solving (1) & (2) M = 40 yrs and K = 32 yrs Hence, Total of ages = 40 + 32 = 72 yrs Difference of ages = 40 - 32 = 8 yrs.

Answer: C) Planet Labs Explanation: American startup Planet Labs, that launches small satellites into orbit and sells the imagery, has announced its acquisition of Google's 'Terra Bella' satellite business. As part of the agreement, 60 Google employees will join the startup founded by ex-NASA scientists. Terra Bella, was acquired by Google in 2014 for $500 million and that time it was known as Skybox Imaging.

Answer: A) C2H6O Explanation: C2H6O is a Non-electrolyte.   An electrolyte is a compound that conducts an electric current when it is in an aqueous solution or melted. In order to conduct a current, a substance must contain mobile ions that can move from one electrode to the other. All ionic compounds are electrolytes. When ionic compounds dissolve, they break apart into ions which are then able to conduct a current ( conductivity ). Even insoluble ionic compounds such as CaCO 3 are electrolytes because they can conduct a current in the molten (melted) state.   A nonelectrolyte is a compound that does not conduct an electric current in either aqueous solution or in the molten state. Many molecular compounds, such as sugar or ethanol, are nonelectrolytes. When these compounds dissolve in water, they do not produce ions.   Electrolytes are of 3 types ---- Strong Electrolytes, Weak Electrolytes and Non Electrolytes.   Strong Electrolytes ---- Compounds which completely dissolves. ( NaCl, Na2Co3, HCl ) Weak Electrolytes ----- Compounds which do not completely dissolves. Non Electrolytes ------ Compounds which do not dissolves at all.
