Answer:
Replication
Explanation:
In science, the work of a scientist is regarded as authentic if other experts in other places can follow the same steps as he/she claimed to follow and arrive at the same result.
For example, a scientist in California, United States of America may carry out a research and publish his findings. Another scientist in Christchurch New Zealand following exactly the same procedure is expected to arrive at the same results as the original researcher if there were no errors in the work.
However, where there are disparities in results, the scientist in Newzealand may discover errors that were unknown to the original researcher in the united States. The New Zealand scientist was carrying out a process known as 'replication'. That is, repeating a scientific research in order to obtain the same results thereby validating the research.

A neutralization reaction is when an acid and a base react to form water and a salt and involves the combination of H+ ions and OH- ions to generate water.
A: sublimation
B: condensation
C: melting
Explanation:
When in a solid between the molecules we have only weak forces the solid may undergo a face transition end by increasing temperature it will transform in a gas without going through the liquid state. This is sublimation.
When we drop the temperature of a gas between a certain limit were the forces between the molecules are no longer inhibited so they will stick together in a liquid form. This is condensation.
When a solid is transformed in a liquid, the temperature is high enough to overcome interactions between the particles so the molecules will gain a degree of freedom. This is melting.
