The balloon will reach its maximum volume and it will burst.

Given:

  • A weather balloon at sea level, with gas at 65.0 L volume, 745 Torr pressure, and 25C temperature.
  • When the balloon was taken to an altitude at which temperature was 25C and pressure was 0.066atm its volume expanded.
  • The maximum volume of the weather balloon is 835 L.

To find:

Whether the weather balloon will reach its maximum volume or not.

Solution:

The pressure of the gas in the weather balloon at sea level = P_1=745 torr

1 atm = 760 torr\\P_1=745 torr=\frac{745}{760} torr = 0.980 atm

The volume of the weather balloon at sea level = V_1=65.0L

The temperature of the gas in the weather balloon at sea level:

T_1=25^oC=25+273.15 K=298.15 K

The balloon rises to an altitude.

The pressure of the gas in the weather balloon at the given altitude:

P_2=0.066atm

The volume of the weather balloon at the given altitude = V_2=?

The temperature of the gas in the weather balloon at the given altitude:

T_1=25^oC=25+273.15 K=298.15 K

Using the Combined gas law:

\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}\\\frac{0.980 atm\times 65.0L}{298.15 K}=\frac{0.066atm\times V_2}{298.15K}\\V_2=\frac{0.980 atm\times 65.0L\times 298.15K}{0.066atm\times 298.15 K}\\=965L

The maximum volume of the weather balloon= V = 835 L

V < V_2

The volume of the weather balloon at a given altitude is greater than its maximum volume which means the balloon will reach its maximum volume and it will burst.

How many oxygen atoms are in 3.70 g of quartz?
Ad libitum [116K]

Answer:

The formula of Quartz is SiO2. So, 1 mole of Quartz will have 2 moles of oxygen atoms, i.e. 2 x 6.022 x 10^23 atoms of oxygen. The molar mass of quartz is 60 g per mol. So, 60 g quartz means 1 mole quartz.

When doing a titration what is the equivalency point of the neutralization reaction?
KengaRu [80]
The equivalency point is at the point of the titration where the amount of titrant added neutralize the solution. When it’s a strong acid strong base titration, the equivalence point will be 7. When it is a weak acid strong base, the equivalence point it more basic (the exact number depends on what acid and base you use). And when it is a strong acid weak base, the equivalence number is more acid (the exact number depends on what acid and base you use). Hope this helps!

A chemist carefully measures the amount of heat needed to raise the temperature of a 894.0g sample of a pure substance from to −
astraxan [27]

Answer:

C = 0.2349 J/ (g °C)

Explanation:

Mass, m = 894.0g

Initial Temperature = −5.8°C

Final Temperature =  17.5°C

Temperature change = 17.5°C - (−5.8°C) = 23.3

Heat, H = 4.90kJ = 4900 J

Specific heat capacit, C = ?

The relationship between these quantities is given by the equation;

H = mCΔT

C = H / mΔT

C = 4900 / (894)(23.3)

C = 0.2349 J/ (g °C)
