when water reacts with potassium metal the hydrogen produced ignites explosively on the surface of water ii.)write an equation to show how this ignition occurs​

K + H2O = KOH + H2

Explanation:

The reaction equation is 4K + O2 → 2K2O. The flame in this reaction has a violet color. therefore the basic equation is : K + H2O ————→ KOH + H2

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
