Question

अभीकारक व उत्पाद से क्या तात्पर्य है किसी रासायनिक समीकरण में उन्हें कहां लिखा जाता है
​

Answer 1

Explanation:

Within' means on the inside, which is not possible in this sentence. It is difficult to hide when 'on' a tree. So, option B is also ruled out. 'In' would indicate that there is some place which leads to the inner part of the tree like a hole. But since nothing as such is mentioned in the sentence, the right answer is 'behind'.

Answer 2

Answer:

समता चिन्ह के बायीं ओर क्रिया करने वाले (अभिकारक) (reactants) लिखे जाते हैं तथा इसके दायीं ओर उत्पाद (products) लिखे जाते हैं। समीकरण का अधार यह है कि किसी रासायनिक अभिक्रिया में भाग लेने वाले भिभिन्न तत्वों के परमाणुओं की संख्या अभिक्रिया के उपरान्त भी अपरिवर्तित रहती है।
