Answer:
NaF(aq)
Explanation:
When sodium bromide react with fluorine sodium fluoride is formed. Florine is more reactive than bromine that's why it displace the bromine and form compound with sodium.
Chemical reaction:
NaBr(aq) + F₂(aq) → NaF(aq) + Br₂(aq)
Balanced chemical equation:
2NaBr(aq) + F₂(aq) → 2NaF(aq) + Br₂(aq)
Sodium is alkali metal and have one valance electron. It loses one electron and show +1 charge. While all halogen elements need one electron to complete the octet and show -1 charge.
That's why one halogen atom is combine with one sodium atom to make overall compound neutral.
The answer is a bit ambiguous since the kinetic molecular theory refers to the behavior of gas molecules, and says that these are in continuous and random motion. All substances with certain conditions of temperature and pressure can be taken to a gaseous state, so I could tell you that this answer is true.
Atomic radius- a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding cloud of electrons.
Electron Affinity-the electron affinityof an atom or molecule is defined as the amount of energy released or spent when an electron is added to a neutral atom or molecule in the gaseous state to form a negative ion.
Electronegativity-a measure of the tendency of an atom to attract a bonding pair of electrons. The Pauling scale is the most commonly used. Fluorine (the most electronegative element) is assigned a value of 4.0, and values range down to caesium and francium which are the least electronegative at 0.7.
Lonization energy- qualitatively defined as the amount of energy required to remove the most loosely bound electron, the valence electron, of an isolated gaseous atom to form a cation.
Answer:
No
Explanation:
The given equation is not balanced
Chemical equation:
KClO₄ → KCl + O₂
Given Balanced chemical equation:
KClO₄ → 2KCl + 2O₂
Correctly balanced chemical equation:
2KClO₄ → 2KCl + 4O₂
Now this equation is correctly balanced.
There are two potassium atom two chlorine atoms and eight oxygen atoms on both side of equation. So this is correctly balanced.
Coefficient with reactant and product:
KClO₄ 2
KCl 2
O₂ 4
