B. Another team of scientists must be able to replicate the results of
the experiment.
Explanation:
Scientists follow due scientific processes in supporting a claim. This process is known as scientific method. A scientific method is a procedural way of investigating an observation. It entails:
- careful observation and measurement
- detailed experiment
- the formulation, testing, and modification of hypotheses
Through this, when a finding is made, before it can be acceptable by the scientific community, it must be tested through a series of experiments by other scientist. These scientists will also test for the validity of the claim that a new element has been discovered.

D. this is because they consume less resources, but produce just as much power. if this is wrong, which i doubt, it is a.
A- and H3O+ interact, causing A-'s concentration to drop and [HA] to rise. As a result, the [NaA]/[HA] ratio declines. Because of the base content, the buffer's pH will be more acidic. The concentration of the acid, HA, has increased while A- has decreased.
What is Acid?
Any material that when dissolved in water has an acidic taste, can alter the colour of some indicators (such as reddening blue litmus paper), can react with some metals (such as iron) to release hydrogen, can combine with bases to produce salts, and can accelerate some chemical reactions (acid catalysis). Acids are examples of organic chemicals that belong to the carboxylic acid, sulfonic acid, and phenol groups as well as the inorganic substances known as the mineral acids, such as sulfuric, nitric, hydrochloric, and phosphoric acids. These chemicals contain one or more hydrogen atoms, which are discharged as positively charged hydrogen ions when they are in solution.
