A sample of argon gas at 55°C is under 845 mm Hg pressure. What will the new temperature be if the pressure is raised to 1050 mm
Maurinko [17]

Answer:

The final temperature at 1050 mmHg is 134.57 ^{\circ}C or 407.57 Kelvin.

Explanation:

Initial temperature = T = 55^{\circ}C = 328 K

Initial pressure = P = 845 mmHg

Assuming final  to be temperature to be T' Kelvin

Final Pressure = P' = 1050 mmHg  

The final temperature is obtained by following relation at constant volume

\displaystyle \frac{P}{P'}=\displaystyle \frac{T}{T'} \\ \displaystyle \frac{845 \textrm{ mmHg}}{1050 \textrm{ mmHg}} = \displaystyle \frac{328 \textrm{ K}}{T'} \\T' = 407.57 \textrm{ Kelvin}

The final temperature is 407.57 K

8. If 0.795 moles of ammonia gas occupies 42.5 L at 670 torr, what is the Celsius temperature?
maksim [4K]

<u>Answer:</u> The temperature in degree Celsius is 301.31°C

<u>Explanation:</u>

To calculate the temperature, we use the equation given by ideal gas, which is:

PV=nRT

P = pressure of the gas = 670 torr = 0.882 atm   (Conversion factor: 1 atm = 760 torr)

V = volume of gas = 42.5 L

n = number of moles of gas = 0.795 mol

R = Gas constant = 0.0821\text{ L atm }mol^{-1}K^{-1}

T = temperature of gas

Putting values in above equation, we get:

0.882atm\times 42.5L=0.795mol\times 0.0821\text{ L atm }mol^{-1}K^{-1}\times T\\\\T=574.31K

Converting the temperature from kelvins to degree Celsius, by using the conversion factor:

T(K)=T(^oC)+273

574.31=T(^oC)+273\\T(^oC)=301.31^oC

Hence, the temperature in degree Celsius is 301.31°C

Determine the name for aqueous H2CO3. carbonous acid dihydrogen carbonate carbonic acid hydrocarbonic acid hydrocarbide acid
BabaBlast [244]

The name for aqueous H_{2} CO_{3} is carbonic acid.

So, option C is correct one.

Binary hydrogen compounds with non metals may form H+ (proton) and an anion dissolved in water. The acidic solutions are named as if they were molecular acids , using the usual name for the compound itself , replacing hydrogen with hydro- and suffix -ide with ic. The word acid is then use.

The inorganic acid is an acid drive from one or more inorganic compounds. All inorganic acids form hydrogen ions and the conjugate base ions when dissolved in water.

Example: carbonic acid ( H_{2} CO_{3} )
