Explanation:
before the reaction you have N=2 and H=6 after the reaction you have N=2 and H=6 so yes it follows the law
Answer:
D
Explanation:
Measurements that are close to a standard measured value is accurate. But when measured values are close to each other they are precise. For example, if one measures the weight of 1 kg of rice as 945 g and another person measure it as 955 g, then the second person’s ,measurement is more accurate. Now if the first person measured the same bag of rice thrice and got values 945 g, 946 g and 947g whereas the second person got values 955g, 950 g and 940 g, in such a case the first person’s measured value is more precise.
Answer:
Explanation:
Atoms are held together by covalent bonds when they share electrons between themselves.
Covalent bonds are bonds that are formed between non-metals usually with a low electronegative difference between them. In this bond type, two non-metals donate electrons which are shared between the combining atoms and this makes them both like the corresponding noble gases. The shared electrons is what forms the covalent bonds.
An example of covalent bond is HCl, H₂S, SO₂, CO₂, O₂ etc
The answer to this would be false.
