Answer:
formula units
Explanation:
is potassium chlorate. It is an ionic compound containing potassium, chlorine and oxygen. The ion in potassium chlorate are held together by the ionic bonds in the lattice structure.
A representative particle may be defined as the smallest unit for which the substance exists in its natural form. For most of the elements, atom is the representative particle. Molecule is the representative particle for diatoms and molecular compounds. But for ionic compounds such as , NaCl, etc. . the representative particle is its formula units.
Answer:
Potassium
Explanation:
Most reactive metal in the reactivity series
I think it’s the inner membrane
Hey there!
K₂Te + Fe(HCO₃)₂ → KHCO₃ + Fe + Te
Start by balancing HCO₃ since it's a polyatomic ion.
Two on the left, one on the right. Add a coefficient of 2 in front of KHCO₃.
K₂Te + Fe(HCO₃)₂ → 2KHCO₃ + Fe + Te
Balance K .
Two on the left, two on the right. Already balanced.
Balance Te.
One on the left, one on the right. Already balanced.
Balance Fe.
One on the left, one on the right. Already balanced.
Our final balanced equation:
K₂Te + Fe(HCO₃)₂ → 2KHCO₃ + Fe + Te
Hope this helps!
Answer:
i. Atomic radius of an atom is defined as the total distance from the nucleus to the outermost shell of the atom.
On moving from left to right ( Mg, K) in a period, more and more electrons get added up in the same shell and the attraction between the last electron and nucleus increases, which results in the shrinkage of size of an atom. Thus, decreasing the atomic radii of the atom on moving towards right of the periodic table.
As moving from top to bottom, there is an addition of shell around the nucleus and the outermost shell gets far away from the nucleus and hence, the distance between the nucleus and outermost shell increases.
Thus the order of atomic radii is : Ca > Mg > K
ii. The energy required to remove the last valence electron from isolated gaseous atom (first ionization energy) increases as we move from left to right in a period. It decreases on moving from top to bottom.
Thus the order of first ionization energy is : K > Mg > Ca
iii. The chemical properties depend on the valence elctrons and as the elements Mg and Ca both have two valence electrons , they have same chemical properties.
