The laboratory compare the mass of the starting reactants in final products of the combustion reaItction A technician determines the mass of a firewood in oxygen reactants before burning to be 2.72 KG after the fire wood finish burning the pile of cooled ash that remained had a mass of 0.095 kg according to the law of conservation of mass matter is neither created nor destroyed in a chemical reaction do the results of the technicians combustion experiment contradict the law of conservation of mass? write a minimum of 5 sentences * I need asappp*

Nitrogen (n), phosphorus (p), and potassium (k) are the main nutrients in plant fertilizers. according to an industry convention, the numbers on the label refer to the mass percents of n, p2o5, and k2o, in that order. calculate the n: p: k ratio of a 30: 10: 10 fertilizer in terms of moles of each element, and express it as x: y: 1.0.

Ab c or d ? i’m not sure what the answer is

Elaborate on the reason(s) that matter is said to move even as in a solid state. select one: a. the particles are bound through intermolecular forces but are able to move past each other with relative freedom. b. the particles have sufficient energy to become an ionized gas and are in the most common state of matter in the universe. c. the particles are not able to move out of their positions relative to one another, but do have small vibrational movements. d. the particles are not bound to one another, move quickly, have a low density, and are able to spread apart from one another if unconstrained.
