Nitrogen and hydrogen combine together to form ammonia. N2 + 3H2→ 2NH3 [Relative atomic masses of N = 14 u, H = 1 u] The mass of nitrogen and hydrogen which combine together to form 6.8 g ammonia is A. N2 = 2.8g, H2 = 4.0g B. N2 = 5.6g, H2 = 1.2g C. N2 = 4.0g, H2 = 2.8g D. N2 = 12g, H2 = 5.6g

Answer»

If N2 = 5.6g, H2 = 1.2g 

According to the law of conservation of mas, 5.6g + 1.2g = 6.8g of ammonia 

Hence, the option (b) is correct
