The model below shows the equation that represents how hydrogen and oxygen combine to form water. 2H2 + O2 → 2H2O Read each statement below and select all that apply to the equation. The number of atoms of oxygen in the reactants is different than the number of atoms of oxygen in the product. The number of atoms of oxygen in the reactants is different than the number of atoms of oxygen in the product. The law of conservation of matter is not applied in this equation. The law of conservation of matter is not applied in this equation. The mass of the reactants is equal to the mass of the products in the reaction. The mass of the reactants is equal to the mass of the products in the reaction. The total number of each type of atom is conserved in the equation. The total number of each type of atom is conserved in the equation.

If a substance is not at its melting or boiling point, as the heat content of a sample of matter increases, its temperature increases the number of intermolecular bonds decreases the space between particles increases the particles move faster

Dying the folding patterns of protein molecules can microbiologists better understand cellular processes as well as some diseases, such as alzheimer’s, that are caused by proteins that have misfolded. the folding of these complicated molecules can be simulated on computers, but it takes a lot of processor power and time for even expensive supercomputers to do this. a group of researchers at stanford university developed software that can be used to distribute the processing of data to anyone who is willing to donate time on their idle personal computers. as a result, the researchers have been able to achieve protein-folding simulations that are far better than those other computing methods have done. which statement best describes the work of these researchers? the work is not scientific because the data are not processed in one location. the work is not scientific because the simulations are not reproducible. the researchers applied creativity to solve a problem in running an experiment. the researchers used only well-established scientific techniques.
