1.3 What is the use of hydrogen gas at 40% for 50ml of h2so4, which is recommended for hydrophilic gas, which is recommended by zodiac sulphate.
Solution of 0.1g KIO3 has been used to cure any of the symptoms of HCL, but it is possible to treat the thiosalphate varies from 45.0 ml to the same level, so that the thososalphate is available
what will be the ph of the solution is zero point zero one mole of hcl is dissolved in a buffer solution containing zero point zero to propanoic acid k e equal to one point three four into ten to the power minus five and zero point zero one five two moles of salt at twenty five degree celsius
a solution is 0.1M in cl^-,0.01M in br^-,0.001M in I^-, agno3 is added to the solution [v mix=0].the concentration of ag+required to start precipitation of all 3 ions is [given,ksp of agcl is 10^-10,ksp of agbr is 10^-13,ksp of agI=10^-7]
A stream of water vapor flowing at a rate of 250 mol/h is brought from 600 degrees Celsius and 10 bar to 100 degrees Celsius and 1 atm. Estimate the required cooling rate in kW using the following three methods:
a. steam tables
b. using specific heat capacity data
c. using specific enthalpy data

which of those answers should be the most accurate and why?

what is the physical significance of the difference between the values calculated with methods 1 and 2?
Physical Characteristics of Gases
Aristotle viewed matter as being made up of _______, earth, ______, and ________. It wasn’t until Robert ___________ studied gases and proposed matter is made up particles called __________.
Pressure is known as the _________ per area on a _____________. Imagine squeezing a balloon. All the pressure that is felt is due to the _______________ of the gas particles that are moving around and bouncing off the ________ of the balloon. The SI unit for pressure is Pascal (____), however _________________ (atm) is used most frequently.

With the following gas law problems, identify the variables that are changing and then identify the gas law equation to use. Make sure you set up the problem properly and solve for the unknown.
1. If you initially have a gas with a pressure of 0.95 atm and a temperature of 35C and heat it to 65C, what will the new pressure be if volume and moles are held constant?
Gas law: _______________


2. A sealed balloon filled with air has an internal pressure of 1.25 atm and a volume of 2.50 L. If the temperature remains constant at 25C, but the volume is compressed to 1.20 L, what would be the resulting pressure?
Gas law: _______________

3. How many moles of gas are sealed inside the balloon in question #2?
Gas law: ________________

4. A sample of nitrogen gas has a volume of 13.5 L at 32C and 2.5 atm. What is the volume when the pressure changes to 1.3 atm, when temperature is constant?
Gas law: ________________
