What may explode in a combustible atmosphere?

Residue blasts can happen where any scattered powdered ignitable material is available in sufficiently high fixations in the air or other oxidizing vaporous medium, like unadulterated oxygen. In situations when fuel assumes the part of an ignitable material, the blast is known as a fuel-air blast.

Explanation:

lithosphere and asthenosphere

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.
