Answer 1

hey mate here is solution !!!

the metal x is na Or it may be (mg,ca,k)

also, but let us take it as na .

now , the acid is HCl ..or it may be {hno3,h2so4}

the reaction given below :-

na + HCl = nacl + h2

so the gas z is h2

its characteristics are :-

na is most reactive element

HCl is the strong acid

and h2 is the gas which burns with a pop sound when bring near a burning splinter ,,,,

hope it helps !!

Answer 2

Howdy!!

your answer is ----

a ) The metals are ---
• Sodium (Na)
• Calcium (Ca)

Suppose X is Na and y is HCl. so , when react this

2Na + 2HCl ====> 2NaCl + H2

so, gas Z is H2

from above discussion we conclude that

when metal react with acid then , salt and hydrogen gas is produce.

ACID + METAL ==> SALT + H2↑
