Which sequence of coefficients should be placed in the blanks to balance this equation? _al + _o2 mc031-1.jpg _al2o3

The sequence of coefficients is 2 , 3 and 2 in

Explanation:

According to law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products must be same as the mass of reactants.

For this, the number of atoms of each element must be same on both sides of the equation. Thus a balanced chemical equation is written.

b i think it’s a water wheel turning in a stream

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.
