Mason was asked to balance the equation that models the reaction between lithium (li) and water (h2o), which yields lithium hydroxide (lioh) and hydrogen gas (h2). then he was asked to record his process. mason performs the correct steps to balance the equation but writes down these steps in the wrong order. a. added a coefficient of 2 in front of the lithium (li) reactant in order to correct the imbalance. b. observed that the equation was balanced. c. noticed the imbalance between the one lithium (li) atom on the reactant side and the two lithium atoms on the product side. d. noticed that the two hydrogen (h) atoms on the reactant side and the three hydrogen atoms on the product side were not balanced. e. added a coefficient of 2 in front of the water (h2o) reactant and the lithium hydroxide (lioh) product in order to correct the imbalance. which option correctly orders the steps mason must have followed to balance the equation li + h2o → lioh + h2? d, e, c, a, b c, a, d, e, b c, e, d, a, b d, a, c, e, b

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.

Agroup of students is studying convection currents. they fill two identical balloons with the same amount of helium. one balloon is placed in a freezer and the other in an area with warm air. after 10 minutes, the balloons are released from a height of 1 meter. which of the following do the students most likely observe? a. the balloons both rise. the cold balloon is larger than the warm balloon. b. the balloons rise at the same rate. both balloons are the same size. c. the warm balloon expands and rises. the cold balloon shrinks and sinks. d. the cold balloon expands and rises. the warm balloon shrinks and sinks.

24 points and brainliest to anyone who can answer under 10 minutes with best ! the table below shows the role of different substances during photosynthesis. substance role during photosynthesis glucose stores chemical energy water combines with glucose to form carbon dioxide chlorophyll traps sunlight which of the following statements would correct one of the roles listed in the table? glucose combines with carbon to form water. chlorophyll reacts with light to produce carbon dioxide. water combines with carbon dioxide during photosynthesis. chlorophyll stores chemical energy needed for photosynthesis.
