Answer:
Explanation:
Molecules are made up of atoms that are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons among atoms.
Molecular mass is a number equal to the sum of the atomic masses of the atoms in a molecule. The molecular mass gives the mass of a molecule relative to that of the 12C atom, which is taken to have a mass of 12.
Answer:
Four electrons are bounded by eight electrons
and the bond order = 4/3
Explanation:
The molecular ion has 24 valence electrons and The SN of N in the central of the structure is = 3 according to VSEPR Theory. and this depicts trigonal planar geometry about the central nitrogen also this corresponds to sp^2 hybridization of the valence orbital of the atom N.
The 6 valence electrons are shared between N and O's, while the 2p orbital of Nitrogen will combine with the 2p orbital on each oxygen atoms in order to form four (4) π molecular orbitals. the binding orbital is occupied by a pair of electrons. Four electrons are bounded by eight electrons
and the bond order = 4/3
Attached below is the Lewis structure and resonance structures of the ion ( NO^- 3 )
Answer:
Hey I really hope this helps!
Explanation:
Temperatures do not affect radioactivity at all. This has been tested many times and at extreme temperatures. Temperature is the average vibrational kinetic energy of the molecules of some object. ... Radioactive decay is caused by imbalances in the nuclear and electroweak forces inside the nucleus of an atom.

The mass of the blood is 5.8 kg.
<em>V</em> = 5.5 L = 5500 mL
Mass = 5500 mL × (1.06 g/1 mL) = 5800 g = 5.8 kg
Answer:
56.24g
Explanation:
To find the mass of N2O3 in 4.45 x 10^23 molecules, it must first be converted to moles by dividing the number of molecules in N2O3 by Avagadro's number (6.02 × 10^23).
number of moles in N2O3 = 4.45 x 10^23 ÷ 6.02 × 10^23
n = 4.45/6.02 × 10^(23 - 23)
n = 0.74 × 10^0
n = 0.74moles.
Using the formula below to find the mass of N2O3;
mole = mass ÷ molar mass
Molar mass of N2O3 = 14(2) + 16(3)
= 28 + 48
= 76g/mol
mass = mole × molar mass
Mass = 0.74 × 76
Mass = 56.24g
