During the extraction of a batch of titanium, 184 tonnes of sodium was used. Calculate the maximum mass of titanium that could be formed during this reaction. [3 marks] TiCl4 + 4Na = Ti + 4NaCl

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

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.

the answer is option a.
