The partial pressure of argon in the atmosphere when the atmospheric pressure is 775. 0 torr is 7.75 torr.
Each gas that makes up a mixture of gases has a partial pressure, which represents the notional pressure of that gas if it were to occupy the entire volume of the initial mixture by itself at the same temperature.
The force that the weight of the atmosphere exerts on a certain area is known as atmospheric pressure.
As we know,
partial pressure is calculated as:
partial pressure = (total absolute pressure) × (volume fraction of gas component)
partial pressure = × 0.010
partial pressure = 775.0 × 0.010
partial pressure = 7.75 torr
Therefore, partial pressure of argon in the atmosphere when the atmospheric pressure is 775. 0 torr is 7.75 torr.

Mechanical Energy
Mechanism energy is the energy associated with the position and motion of an object. Therefore it is also the summation of the kinetic and potential energies of the object.
Explanation:
Mechanism energy is the energy associated with the position and motion of an object. Therefore it is also the summation of the kinetic and potential energies of the object.
In the muscles, to have movement, the chemical bonds in ATP is broken to enable the sliding action of the myosin and actin fibres of a sarcomere (the basic unit of muscle). This sliding action is responsible for contraction of muscle. The coordinated contractions and relaxations of sarcomeres on muscles result in movement which translates to mechanical energy.
This process is never 100% efficient with some energy lost as heat energy.

It is endothermic and the ∆H = +393.5 kJ.
Answer:
2,772 seconds is the half-life of this reaction.
Explanation:
The rate constant of the reaction = k =
From the unit of rate constant, the order of reaction will be 1.This is because the unit of the rate constant the reaction following first order kinetics is time inverse.
For first order kinetic half life () and rate constant (k)are related by :
2,772 seconds is the half-life of this reaction.
