Answer:
The final pressure of the carbon dioxide gas will 11.84 atm.
Explanation:
Moles of carbonic acid = 
According to reaction, 1 mol of carbonic acid gives 1 mole of carbon dioxide gas.
Then 0.9677 moles of carbonic acid will give :
of carbon dioxide
Moles of carbon dioxide gas = n = 0.09677 mol
Volume of soda bottle = 
Pressure of the carbon dioxide gas = P
Temperature of the carbon dioxide gas = T = 298 K
(ideal gas law)
The final pressure of the carbon dioxide gas will 11.84 atm.
Answer:
P = 741.7 Pa
Explanation:
Pressure:
It is the force applied on object per unit area. The force is applied perpendicular to the surface.
Mathematical expression:
P = F/A
P = pressure
F = force
A = area
Given data:
Weight = 178 N
Area = 10 cm × 24 cm
Pressure = ?
Solution:
Area = 10 cm × 24 cm
Area = 240 cm²
Area = 240 /10000 = 0.024 m²
Formula:
P = F/A
P = 178 N / 0.024 m²
P = 741.7 Nm⁻²
Nm⁻² = Pa
P = 741.7 Pa
Temperature is a measure of the average kinetic energy of the particles in a substance. It is the kinetic energy of a typical particle. Temperature is a measure of the average kinetic energy of the particles. in a substance.
PE= weight x height. (remember weight is the force of gravity acting on objects...NOT the same as mass)
PE=3*2*9.8
PE=6*9.8
PE=58.8 J (for joules which is the unit for both Kinetic and potential energy)
Hope this helps :D
