Answer:
285.4 moles of gas are in a 35.0 L scuba canister if the temperature of the canister is 27.3 °C and the pressure is 200.8 atm.
Explanation:
An ideal gas is a theoretical gas that is considered to be composed of randomly moving point particles that do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.
An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of the gases:
P * V = n * R * T
In this case:
- P= 200.8 atm
- V= 35 L
- n=?
- R= 0.082

- T= 27.3 C= 300.3 K (being O C= 273 K)
Replacing:
200.8 atm* 35 L= n* 0.082
* 300.3 K
Solving:

n= 285.4 moles

Q=hc A (Ts-Ta)
q = heat transfered per unit time
A= heat transfer area of the surface
hc= convective heat transfer coefficient of the process
Ts= temperature of the surface
Ta= temperature of the air
Answer:
If NH4+ is removed, the reaction will shift toward products to replace the product removed. This means the reaction will shift to the right.
Explanation:
A solution of ammonia NH3(aq) can be written through the following equation:
NH₃(aq) + H₂O(l) ⇌ NH₄⁺(aq) + OH⁻(aq)
If the concentration of one of the reactants changes, the balance will shift in such a way that the change in concentration is counteracted.
If NH4+ is removed, now there is less product, so the reaction will shift toward products to replace the product removed. This means the reaction will shift to the right.
This principle is due to the fact that the equilibrium constant for this reaction is constant at a certain temperature. The ratio of reactants and products is fixed. Any change in concentration disrupts the balance and will result in the balance being restored.
