Answer : The pressure of the gas is, 0.964 atm

Solution : Given,

Volume of gas = 9040 ml = 9.040 L        (1 L = 1000 ml)

Moles of gas = 0.447 moles

Temperature of gas = -35.50^oC=237.5K       (0^oC=273K)

Using ideal gas equation,

PV=nRT

where,

P = pressure of the gas

V = volume of the gas

T = temperature of the gas

n = number of moles of gas

R = gas constant = 0.0821Latm/moleK

Now put all the given values in this formula, we get the pressure of the gas.

P(9.040L)=(0.447moles)\times (0.0821Latm/moleK)\times (237.5K)

By rearranging the terms, we get

P=0.964atm

Therefore, the pressure of the gas is, 0.964 atm

Kruka [31]

Answer:

Most higher risk volcanoes are far from California’s largest cities and several produce heat that’s used to generate electricity in what are the world’s most productive geothermal power plants, such as the Salton Buttes, 160 miles southeast of Los Angeles, and the Clear Lake Volcanic Field 85 miles north of San Francisco that powers the Geysers steam field.

Aqueous nitric acid and aqueous ammonia reacts to form ammonium nitrate 
 HNO₃(aq)+NH₃(aq) = NH₄NO₃(aq)
 HNO₃ +NH3 = NH₄ (+) + NO₃ (-)
Therefore the net ionic equation will be;
 H⁺(aq) + NH₃ = NH₄⁺ (aq)
