Recall that force=mass times acceleration. explain why the acceleration of a model rocket increases over time, even if the force from the burning of the rocket fuel remains constant

Particles vibrate in a rigid structure and do not move relative to their neighbors.

Covalent bonds generally form when the bonded elements have a difference in electronegativity less than 1.5. subtract the electronegativities for the following pairs of elements and predict whether they form a covalent bond. electronegativity difference of c and c: ionic covalent electronegativity difference of mg and cl: ionic covalent

Ok, so i have 2 questions. try to answer them both: (the topic is fire) 1) how can you represent the chemical reaction of fire? 2) what kind of bond is formed in this chemical reaction
