That can be deduced from the geological layer in which it is found; or (probably more accurate), radiometric dating can be used.
Probably, carbonateous fossil.

The tools that a scientist would use to conduct an experiment would vary greatly on the nature of the experiment.
I probably would, with proper funding.
You would call it a dead dinosaur. You could refer to a fresh body as a dinosaur carcass. One that is only bones would be a dinosaur skeleton. However, you probably would never see the above. A fossilized dinosaur is called a dinosaur fossil.

It depends on what is meant by dinosaur. The islands of Hawaii are relatively new in geologic terms, about 30 million years for the oldest part of the chain while the age of the dinosaurs ended 65 million years ago. So while there may be fossilized remains they would not be of dinosaurs.
A scientist is doing an experiment to see how oxidation affects the mass of iron-based metals. Which of the following instruments would best help the scientist determine the results of his study?
A scientist who examines the shape of the head to determine causes of human behavior would likely be known as a phrenologist. Phrenology is a pseudoscience that suggests personality traits can be determined by studying the shape and features of the skull.
As this is an international site we would need to know your nationality to determine who is 'foreign' to you.
