A chemist tests new mixtures for paint samples and decides one mixture's stickiness makes it worthless. A scientist working in a nearby lab suggests a different use for this sticky mixture. Which statement best describes this situation? (2 points) Combining different types of scientists' comments always leads to new discoveries. Only scientists who are directly involved in an investigation should comment on the results. Other scientists' comments made during an investigation can be a useful source of new ideas. Too many comments made by scientists about the work of others can interfere with progress.

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).

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.
