answers: 1,3,5 on ed-genuity

thanks for the answers ッ. (btw they’re on the bottom of the question if anyone doesn’t see it.

The correct answer are Option 1, Option 3 and Option 5.

Explanation:

Alpha particles are released when a nucleus undergoes alpha decay process. The alpha particle released carries a charge of +2 units and has a mass of 4 units.

The charge of this particle will determine the number of protons present in this particle which are 2 and the mass will determine the number of neutrons in this particle.

Number of neutrons = Mass number - Number of protons

Number of neutrons = 4 - 2 = 2

This particle also releases energy with itself.

Hence, the correct answer are Option 1, Option 3 and Option 5.

- lead + phosphoric acid = hydrogen + lead(ii) phosphate

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.
