Bases increase the concentration of hydronium ions by donating hydroxide ions to water molecules is False.
<u>Explanation:</u>
Bases are counterparts of acids. They take Hydronium protons from water, and increase the OH- I ions in the solution. One example for this could be ammonia.
When ammonia is added to a solution it accepts a proton of hydronium and becomes ammonium ion.
Solutions which posses’ higher concentrations of hydronium are called acidic solutions and those possessing lower concentrations of hydronium ions are basic in character. Also, pure water is neither acidic nor basic; therefore the concentration of hydronium ions in pure water is neutral.
Answer: Consensus
Explanation:
Consensus is process of decision-making that looks at an agreement among a group and that explains the questions above.
Observational methods, case-study methods and survey methods.
Observational Method
With the observational method (sometimes referred to as field observation) animal and human behavior is closely observed. There are two main categories of the observational method — naturalistic observation and laboratory observation.
Case Study Method
Case study research involves an in-depth study of an individual or group of indviduals. Case studies often lead to testable hypotheses and allow us to study rare phenomena. Case studies should not be used to determine cause and effect, and they have limited use for making accurate predictions.
Survey Method
In survey method research, participants answer questions administered through interviews or questionnaires. After participants answer the questions, researchers describe the responses given. In order for the survey to be both reliable and valid it is important that the questions are constructed properly. Questions should be written so they are clear and easy to comprehend.
Answer:
less
Explanation:
In case of rolling friction, the area of contact is less than in the case of sliding. Due to this, rolling friction is <u>less</u> than sliding friction.
As a body rolls upon another, it experience the resistance to motion which is known as rolling friction.
Sliding friction refers to a contact force that resists the sliding motion of two bodies.
