The average mass of a neutron is
1.674929 u :)
Can I get brainlyest please
Average mass of proton is 1.007276 u and that of neutron is 1.008664 u
There are 3 subatomic particles present in an atom. They are: protons, electrons and neutrons.Protons: They carry positive charger and are found in nucleus.Electrons: They carry negative charge and are found around the nucleus.Neutrons: They dos not carry any charge and are found in nucleus.
Mass of electron is almost negligible as compared to the mass of proton and neutron.
Masses of the subatomic particles:
Mass of protons = 1.007276 u
Mass of neutrons = 1.008664 u
Mass of electrons = 0.00054858 u
Hence, average mass of proton is 1.007276 u and that of neutron is 1.008664 u
1 amu. correct. 100000000000000000000000000000000000000%
The answer is a) 1 amu
The definition of an atomic mass unit (amu) is the mass of a single proton or neutron, so by definition, these particles have a mass of 1 amu.
we must remember that nitrogen and hydrogen are both diatomic molecules in their standard gas form. this adjusts the equation to
now we need to adjust coefficients in order to balance the atoms on each side of the equation. currently we have 2 atoms of nitrogen and 2 atoms of hydrogen on the reactant side and 1 atom of nitrogen and 3 atoms of hydrogen on the product side.
we can balance the hydrogens by placing a coefficient of 2 in front of ammonia and a coefficient of 3 in front of the hydrogen.
this gives us 6 hydrogen on each side and coincidentally the nitrogens now equal 2 on each side.
the correct name for the n3 ion is azide. azide is a polyatomic anion with a -1 charge and is written as n3 -1. it consists of three nitrogen atoms bonded together. hope i . let me know if you need anything else.
