PV = nRT
P = 157 kPa = 157 × 10³ Pa
V = 265 ml = 0.265 l
T = 20°C = 293 K
m = 0.479 g
PV•M = mRT
M = (mRT)/(PV)
M = 0.479 g × 8.314 kPa.l/(mol.K) × 293 K / (157 kPa × 0.265 l)
M ≈ 28.04579 g/mol.
Hence, the Molar Mass of Dinitrogen or Nitrogen Gas is 28 g.
Ideal gas law, Charles law, Boyle's law.
<u>Explanation:</u>
Gas laws:
Charles law: Volume of a gas is directly proportional to the temperature.
V∝T
Boyle's law : Pressure of a gas is inversely proportional to the volume of a gas at constant temperature.
PV= k
Ideal gas law is the combined law of Charles and Boyle's law, PV = nRT.
Ok so we know that all of these are non metals therefore they will bond using covalent bonds.
Phoshorus can have 3 bonds Chlorine can have 1 bond and Oxygen can two bonds.
Cl-P=O
The chemical formula I belive is PClO hope this helps :).
Answer: combustion
Explanation:
Combustion reactions can be identified by looking at the reactants and the products.
Usually, the reactants will be a hydrocarbon and oxygen. And the products will be CO2 and H2O
Explanation:
Newton's second law of motion states that the acceleration of an object is dependant on the amount of force applied and the mass of the object itself, which is illustrated by the equation
,
where 
is the force applied, 
is the mass of the object and 
is the acceleration.
Therefore,
Hence, 6000 N of force is applied by the engine to the car.
