Question

A vial containing water, its lid, and an Alka-Seltzer tablet are placed on the pan of a balance. The reading on the balance is 12.8 g. The tablet is dropping into the water and the vial immediately sealed. The tablet becomes smaller and eventually disappears, and bubbles smaller and eventually disappears, and bubbles form. Will the reading on the balance be less than, equal to, or greater than 123.8 g? Why?

i honestlyy sayy it don't rightt? it stays the same but that's myy guess. anyone can help me?

Answer 1

The problem has a problem, or it may be a typo, but did you mean the initial reading was 123.8 g? I assume the initial reading should be 123.8 g. With no place for the products to go, they must stay in the sealed vial; therefore, the balance will read the same, 123.8 grams.
