IV.Classify as to what type of chemical reaction each one belongs:
C6H1O6 → 12C + 11 H2O
CdCl2 + H2S → CdS + 2HCl
2Al + O2 → Al2O3
Mg + H2SO4 → MgSO4 + H2
CaCO3 → CaO + CO2
Na2O + H2O → 2NaOH
FeCl3 + 3NaOH → Fe(OH)3 + 3NaCl
3H2 + Fe2O3 → 3H2O + 2Fe
2H2 + O2 → 2H2O
H2CO3 → H2O + CO2
Conversion for Temperature readings: Fill up the table by computing the derived value:

Determine what kind of Gas Laws stated in the following problem:
A given mass of gas occupies a volume of 220 ml. A 700 mm Hg and 20 0C. Compute for the volume of a gas at STP.
1.00 L of a gas at standard temperature and pressure is compressed to 473 mL. What is the new pressure of the gas?
In a thermonuclear device, the pressure of 0.050 liters of gas within the bomb casing reaches 4.0 x 106 atm. When the bomb casing is destroyed by the explosion, the gas is released into the atmosphere where it reaches a pressure of 1.00 atm. What is the volume of the gas after the explosion?
Synthetic diamonds can be manufactured at pressures of 6.00 x 104 atm. If we took 2.00 liters of gas at 1.00 atm and compressed it to a pressure of 6.00 x 104 atm, what would the volume of that gas be?
The highest pressure ever produced in a laboratory setting was about 2.0 x 106 atm. If we have a 1.0 x 10-5 liter sample of a gas at that pressure, then release the pressure until it is equal to 0.275 atm, what would the new volume of that gas be?
If we have 2 L of methane gas at a temperature of 40 degrees Celsius, what will the volume be if we heat the gas to 80 degrees Celsius?
If we have two liters of a gas at a temperature of 420 K and decrease the temperature to 350 K, what will the new volume of the gas be?
If I have 4 liters of a gas at a pressure of 3.4 atmospheres and a temperature of 300 K, how many moles of gas are present?
