Answer:
A star begins its life as a cloud of dust and gas (mainly hydrogen) known as a nebula. A protostar is formed when gravity causes the dust and gas of a nebula to clump together in a process called accretion. ... If a critical temperature in the core of a protostar is reached, then nuclear fusion begins and a star is born.
Explanation:
.
2.45 °C
From the Ideal gas law (Combined gas law)
PV/T = P'V'/T' .....eq 1
Where:
P - initial pressure
V - initial volume
T - initial temperature
P' - final pressure
V' - final volume
T' - final temperature.
To proceed we have to make T the subject from eq.1
Which is, T = P'V'T/PV.......eq.2
We have been provided with;
Standard temperature and pressure (STP)
P = 760 mm Hg (SP - Standard Pressure)
T = 273.15 K (ST - Standard Temperature)
V = 62.65 L
P' = 612.0 mm Hg
V' = 78.31 L
T' = ? (what we require)
Therefore, we substitute the values into eq.2
T' =
.
T' = 275.60 K
T = (275.60 - 273.15) ......To °C
T = 2.45 °C

Answer:
Because his first law states that an object with a net force of zero acting on it will remain at rest, if initially at rest, or it will maintain a constant velocity.
Answer: <span>There are more reactants than products at equilibrium.
Explanation:
</span>1) The equilibrium constant is defined as the ratio of the constant of reaction for the forward reaction divided by the constant of reaction for the reverse reaction.
2) If the constant of reacton for the forward reaction is greater than the constant of reaction for the reverse reaction, then the equilbrium constant is greater than 1 and the equilibrium is reached at a point where there are more products than reactants.
This is not the case given that the equilibrium constant is less than 1.
3) If the constant of reaction for the forward reaction is less than the constant of reaction for the reverse reaction, then the equilibrium constant is less than 1 and at equilibrium there will be more reactants than products.
This is the case given, since the equilibrium constant is 0.123.
Therefore, the answer is: there are more reactants than products at equilibrium.
