Answer : Average atomic weight of copper atoms will be
63.62 u.
Explanation : For calculating average atomic weight for any given atom we use this formula,
m = Σ
X % abundance
where, m - avg atomic mass of isotope.
and
- mass of isotope
on solving we get,
m = [63 u X (69/100)] + [65 u X (31/100)] = 63.62 u.
Answer:
Those in lightning are charged and those in water are not charged.
Explanation:
The particles in lightning differs from those in a water in that water molecules are neutral and those of lightning are charged.
Lightning is made up of charged ions or particles that have either lost or gained electrons.
Lightning is produced as a burst or discharge of charged particles that are imbalanced withing the clouds.
Water molecules are made up of hydrogen and oxygen atoms which forms molecules held together by strong intermolecular and interatomic bonds.
Due to the sharing of electrons that has made this bonding possible, there is a net charge balance which leads to a neutrality.
Water is electrostatically neutral and not charged.
5.8 is 11.2% of what number
51.786 grams
Answer:
Explanation:
Diiodine pentoxide is I₂O₅
Reaction with water
I₂O₅ + H₂O = 2HIO₃
2 ) HIO₃ is called iodic acid.
Explanation:
The electrons in the outermost electron shell are responsible for forming chemical bonds. These electrons are also known as valence electrons
