What is the formula and name of the compound produced at the end of the virtual lab, and what caused it to have a different appe
Iteru [2.4K]

Answer: SnO_2 , NO_2 and H_2O are formed at the end of the reaction. They are named as tin (IV) oxide or stannic oxide, nitrogen dioxide and water respectively.

Explanation: Reaction of tin and nitric acid is given as:

Sn(s)+4HNO_3(aq.)\rightarrow SnO_2(s)+4NO_2(g)+2H_2O(l)

Three products are formed at the end of the reaction which are:

  • SnO_2 which is termed as stannic oxide or Tin (IV) oxide. This is a white colored solid.
  • NO_2 which is termed as nitrogen dioxide. These are brown colored fumes.
  • H_2O which is termed as water.

At the starting tin was a silvery-white colored solid and after the reaction, it changed the color to milky-white. This change in color is due to the chemical reaction happening between tin and nitric acid.

Release of brown fumes are also an indication that a chemical reaction has taken place.

If a stock solution of 20.0 g of sugar per 100. ml of solution is available, how much of this stock is needed to prepare 10.0 ml
Vladimir79 [104]

You must use 2.50 mL of the concentrated solution to make 10.0 mL of the dilute solution.

We can use the dilution formula

<em>V</em>_1<em>C</em>_1 = <em>V</em>_2<em>C</em>_2

where

<em>V</em> represents the volumes and

<em>C</em> represents the concentrations

We can rearrange the formula to get

<em>V</em>_2 = <em>V</em>_1 × (<em>C</em>_1/<em>C</em>_2)

<em>V</em>_1 = 10.0 mL; <em>C</em>_1 = 5.00 g/100. mL

<em>V</em>_2 = ?; ____<em>C</em>_2 = 20.0 g/100. mL

∴ <em>V</em>_2 = 10.0 mL × [(5.00 g/100. mL)/(20.0 g/100. mL)] = 10.0 mL × 0.250

= 2.50 mL
