52 C in a P represents 52 Cards in a Pack. Similar to  12 S of the Z  5 C in an OF

Answer: B) Uncle Explanation:

Answer: B) K x K= JL Explanation: Let the Time be 'N' and Rate be 'R'  J = (K x NR)/100 K = (L x NR)/100  J/K = NR/100 K/L = NR/100  J/K = K/L  K x K = JL

Answer: B) 63 Explanation: Here the series follows the pattern that, product of succesive prime numbers i.e,  2 × 3 = 6  3 × 5 = 15  5 × 7 = 35  7 × 11 = 77  11 × 13 = 143  13 × 17 = 221  17 × 19 = 323 So here in place of 77 the number 63 is written. So the wrong number is 63.

Answer: D) All the above Explanation: All the given reactions are Decomposition reactions. Decomposition reaction is a reaction in which only one reactant is splitted into two or more products.

Answer: C) +4 Explanation: The given compound is NaHCO3 Sodium bicarbonate which is commonly known as Baking soda. Oxidation numbers are the charges on ions. When a neutral atom loses electrons it becomes positively charged. When a neutral atom gains electrons it becomes negatively charged.   Here the C represents the oxidation state of carbon in this compound. Compounds are electrically neutral, which is why we set the sum of the oxidation states equal to zero. Sodium has a +1 oxidation state. Hydrogen has a +1 oxidation state. Oxygen has a -2 oxidation state. There are three oxygen atoms, which means the total oxidation state provided by both oxygen ions is -6. Adding up these oxidation states we get: 1 + 1 + (-6) + C = 0 -4 + C = 0 => C = 4 This means the oxidation state of carbon in this compound is +4.
