.130 g sample of an unknown metal x reacted with hydrochloride acid according to the following chemical equation. The volume of hydrogen gas collected over water was 92.0 mL at 20 C and 763 mmHg. Calculate the atomic mass of unknown metal and identify the metal from the periodic table

a. they are both space stations

happy to

pls mark as brainliest.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

im pretty sure its b
