C isotopes is the correct answer. Isotopes are variants of a particular chemical element which differ in neutron number, and consequently in nucleon number.All isotopes of a given element have the same number of protons but different numbers of neutrons in each atom.
Hope this helps! :)
Answer:
All the compounds are covalent compounds . This means that they are formed by the sharing of pair of electrons.
Basically its just an air like fluid with chemicals.... just like air it just goes as it pleases and fills space
Answer: Carbon tetrachloride Or Tetrachloromethane
Explanation: Carbon tetrachloride is an important nonpolar covalent compound. You determine its name based on the atoms present in the compound.
the basic measurements of length, volume, and mass are 1 meter, 1 meter³ and 1kilogram.
One 10-millionth of the distance from the North Pole to the equator would equal one meter.
A cube with sides of one meter has a volume of one meter³.
The mass of 1,000 cubic centimeters of water is very close to (and was originally intended to be exactly) one kilograms.
but today a more precise way to define is available in which:
1 meter is defined as the distance traveled by light in 1/3×10⁸ sec.
The weight of a specific platinum-iridium prototype held by the International Bureau of Weights and Measures is defined as 1 kg.
moreover these measurements are man made and are not absolute and therefore many new units of measurement can be defined as long as they are fundamentally same everywhere.
