In a metered-dose inhaler (MDI), such as those used for asthma medication, medicine isdelivered by a compressed-gas propellant. (The device is similar in concept to a can of spraypaint.) When the inhaler is activated, a fixed amount of the medicine suspended in thepropellant is expelled from the mouthpiece and inhaled. In the past, chlorofluorocarbons(CFCs) were used as propellants; however, because of their reactivity with the Earth's ozonelayer, they have been replaced by hydrofluorocarbons (HFCs), which do not react withozone. Now HFC use is also being reduced due to their high global warming potential. In one brand of inhalers, the original CFC propellant was replaced by HFC 227ea (C3HF7,heptafluoropropane). The volume of the inhaler propellant reservoir is 1.00×102 mL, and thepropellant is charged into the reservoir to a gauge pressure of 4.443 atm at 23°C. An onlinesearch for properties of HFC 227ea yields the information that the critical temperature andpressure of the substance…
Hello, I'm having difficulties to answer the chemistry problem. Can you please help me with all the parts? I really need help. Also, I need to be prepared for the exam. Please I need help with all the parts a,b,c,d. 7. A 4.82g sample of iron is heated to 84.3 C. A 1.25 g sample of gold is heated to 95.1 C. Both of these metals are added to 9.47 g of cold water that is initally at 14.5 C. a) From the first law of thermodynamics, what is the equation relating the sum of heats of two components? b) Algebraically substitute in the specific heat capacites for the metal and water, the masses of the samples, and the temperature change (see problem 7.) c) Solve the algebraic problem (b) for the Tp the final temperature of water. d) Determine the final temperature of the metals in water. Hint: it's the same for all three components.

-If ethanol (S.G. = 0.790) were used rather than water in measuring the density of the irregular objects, how would that have affected the result? Explain. -When you were measuring the volume of the irregular solid you were told to stir to eliminate bubbles. If the bubbles were not eliminated, how would that affect the density? Explain. -Suppose the density of 65.0 mL of some liquid was found to be 0.748 g/mL. What would be the specific gravity of 45.0 mL of this liquid?

In a river with a constant flow rate, the factory releases wastewater containing NaCl at a concentration of 200 mmol / L to the river at 20.0 L / s. The Na+ and Cl- concentrations at the downstream observation point were 1.00 mmol / L and 0.800 mmol / L, respectively. What is the river flow Q and Cl- concentration before the inflow of drainage? The river originally contains 0.500 mmol / L of Na+.
