A piece of antimony with a mass of 17.41 g is submerged in 46.3 cm3 of water in a graduated cylinder. The water level increases to 48.9 cm3. The correct value for the density of antimony from these data is: + CHEM133 Course Hero

6.696 g/cm3

Explanation:

From the question;

Mass = 17.41g

Volume of water before = 46.3 cm3

Volume of water after = 48.9 cm3

Volume of antimony = Volume after - Volume before = 48.9 - 46.3 = 2.6 cm3

Density = Mass / Volume

Density = 17.41 / 2.6 = 6.696 g/cm3

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.
