What isotope of carbon has been chosen as the reference isotope for atomic mass unit?
carbon 12
The atomic mass unit is presently based on assigning an exact integral mass to an isotope of what?
The atomic mass unit is based on assigning an exact integral mass to the carbon-12 isotope. This isotope was chosen as the reference because it is abundant in nature and has a relative atomic mass very close to 12.
Why was carbon chosen as the base amu thay could have used any other element?
Carbon was chosen as the base atomic mass unit (amu) because it has a stable isotope, carbon-12, that serves as the reference isotope. Carbon-12 is widely available in nature and has an atomic mass of exactly 12 amu, making it an ideal choice for defining the atomic mass unit. Additionally, carbon is abundant in organic compounds, which are the basis of life on Earth, making it a practical and relevant choice for scientific calculations.
What is the standard for comparison for the relative masses listed n the periodic table?
The standard comparison for atomic weights on the periodic table is carbon 12. This is a common isotope of carbon which has 6 protons and 6 neutrons. Carbon 12 is assigned an atomic mass of 12, and other elements' atomic masses are all relative to this value.
In1961 what replaced oxygen as a standard of comparison for the atomic weight of each element?
In 1961, carbon-12 replaced oxygen as the standard of comparison for the atomic weight of each element. This change was made to improve accuracy and consistency in atomic weight measurements. Carbon-12 was chosen because it is more abundant and forms a wider variety of compounds than oxygen.

What element was chosen as the standard foe defining the mole?
Carbon-12 was chosen as the standard for defining the mole because it has a precise atomic mass of 12 atomic mass units, making calculations easier for chemists to work with. This decision was made by the International Union of Pure and Applied Chemistry (IUPAC) in 1961.
Does the trajectory of a point depend on the chosen reference?
No, the trajectory of a point is independent of the chosen reference frame. The trajectory is determined solely by the motion of the point, and is not affected by the choice of reference frame used to describe that motion.
Is the trajectory of a moving point does not on the chosen reference?
Yes it is
What is the reference that he was one of the 12 Apostles chosen by Jesus?
St. Mark was not one of the 12 chosen by Jeasus.
Was dropping atomic bombs chosen by the US?
no Kennedy decided
Does the trajectory of a moving point depend on the chosen reference?
No, the trajectory of a moving point does not depend on the chosen reference frame. The trajectory is a physical path that the point follows through space, and it remains the same regardless of the reference frame used to analyze it.
Why do reference points that are stationary are chosen to determine whether an object is in motion?
To help you state how the reference point placement is and how the object is moved from the reference point
