How would Quartz react with hydrochloric acid? I know precious metals are refined through acids and dissolution, but what about using hydrochloric or nitric acid on quartz, would it react with the silicon dioxide and dissolve the quartz leaving behind the metals that arent affected by the acids?


When a 1.50 g sample of sucrose, C12H22O11 (s), is burned in a bomb calorimeter assembly, the temperature of the system rises from  21.40°C to 28.28°C. If the heat capacity of the calorimeter is 3.60 kJ/°C, a) Calculate the molar heat of combustion of sucrose, in kJ/mol.

b) Verify the claim of sugar producers that one teaspoon of sugar (about 4.8 g) contains only 19 Calories (food Calories).



A steel cylinder of 50 L capacity contains helium gas at a pressure of
200 atm and temperature of 27 oC. Assume that all of the gas can be
used to fill a weather balloon which is released in air. At a height of
100000 ft, the volume of the balloon is 200 m3 and its temperature is
-73 o C. What is the pressure of the gas inside the balloon?
The pressure of a given mass of gas is tripled and the temperature in
kelvin scale is doubled. Find the percentage change in volume.

Butane with an evaporation temperature of 0°C is used as liquefied gas in camping stoves. Butane is also a great power for summer hikers in Finland as a gas for a camping stove. One summer day the temperature was + 15°C and the air pressure 0.95 bar. Calculate how many liters of carbon dioxide was formed when a hiker boiled a 450-gram bottle of butane gas. Suppose the combustion was complete and that the hiker managed to cook the bottle empty (in fact, the same pressure remained inside the bottle as it was outside the bottle).
2. Phosphorus (V) oxide P4O10 is used to prepare phosphoric acid.

a) Write the reaction equation when solid phosphorus (V) oxide is prepared by burning solid phosphorus P4.

b) How much phosphorus (V) oxide can be produced when 1.33 g of phosphorus and 5.07 g of oxygen are available?

Question if I have a cocktail they normally has 4 ounces of ingredients varying between different liquors how can I combine all these into a concentrate to make a smaller volume of liquid meaning 2 ounces instead of 4 ounces
