Which instrument would a scientists use to measure out an exact mass of a dry chemical?
A Scientist would use a balance, either triple-beam or electronic.
What instrument would a scientist use to to measure out an exact mass of a dry chemical?
A laboratory balance (scale)
The chemical name represents the drug's exact formula is this true or false?
False. The chemical name of a drug does not necessarily represent its exact formula. The chemical name is a unique name assigned to a specific compound based on its chemical structure, while the drug's formula represents the elements and their proportions in the compound.
Why do scientists picture electrons as a cloud around the nucleus?
Scientists picture electrons as a cloud around the nucleus because electrons occupy regions of space around the nucleus called orbitals, which represent the probability of finding an electron in that specific region. This cloud represents the uncertainty in the exact position of an electron due to its wave-like nature, as described by quantum mechanics.
Is Ba a metal?
Yes, indeed, Barium ( Ba ) is a metal. An alkaline metal to be exact.

When do scientists have to rely on estimate?
Scientists must rely on estimates when they cannot obtain exact numbers.
Approximately how long do scientists think chemical evolution took?
Scientists estimate that chemical evolution, the process by which life emerged from prebiotic molecules, likely took place over millions to billions of years on early Earth. The exact timing is difficult to pinpoint due to limited geological evidence, but it is believed to have occurred gradually over a long timescale.
What Approximately how long do scientists think chemical evolution took?
Scientists believe that chemical evolution, the process by which simple molecules formed more complex ones, likely took hundreds of millions to billions of years to occur on early Earth. The exact timeline is difficult to determine precisely due to the lack of direct evidence, but current estimates are within that range.
If scientists cannot obtain exact numbers they should rely on a?
answer
Are all atomic masses known exactly?
No. Atomic masses have to be determined by using measuring instruments, which means that they can never be determined precisely. Every measuring instrument has a limit to its accuracy. There is wide agreement that it is impossible to build a perfect measuring instrument. Scientists have constructed some amazingly accurate measuring techniques, but no exact ones.
5 How do scientists know the exact spot where an earthquake begins?
Scientists use instruments called seismometers to detect and record seismic waves emitted by earthquakes. By analyzing the timing and intensity of these waves at different monitoring stations, scientists can triangulate the epicenter of the earthquake and determine its exact location.
