The motion of particles In different states is difficult to observe. A student used computer software to represent the movement of particles in the solid state. Which type of scientific model did the student use? A. a simulation because it imitates an intrinsic process in the molecule

B. a simulation because it helps visualize the orientation of atoms in the molecule

C. a 3-dimensional model because it helps visualize the orientation of atoms in the molecule

D. a 3-dimensional model because it imitates intrinsic processes in the molecule

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

just did the assignment and the answer was #1 +2 n

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
