Answer:

6.09 M

Explanation:

M(HCl) = 1 +35.5 = 36.5 g/mol

85.6 g * 1 mol/36.5 g = 2.3452 mol HCl

Molarity = mol solute/ L solution = 2.3452 mol/0.385 L = 6.09 mol/L =6.09 M

A student has a balloon that looks shiny like a metal and wants to perform an experiment to determine if it contains any metal.
zheka24 [161]

Answer:

Charge the balloon, hold it near an electroscope, and determine if the electroscope leaves move.

Explanation:

The gold leaf electroscope is an instrument used to detect if a body is charged. It has two gold leafs suspended from a brass stem in a vacuumed glass jar and connected to a metal cap(Toppr).

When the test body is allowed to touch the metal cap, a change in the size of the leaves shows whether the body is charged or not.

Since we are suspecting the balloon to be made up of a metal; metals can be charged. We can test if there is really a charge on the balloon by bringing it near an electroscope to see if the electroscope moves.
