<span>That would be compound!
Compounds are pure substances, which consists of two or more elements chemically combined in a fixed proportion by mass. Compounds have definite proportion.</span>
Answer: amount of substance n = cV = 2.0 mol/l x 0.25 l = 0.50 mol
Explanation:
I think the correct answer from the choices listed above is the first option. When the the pressure is increased, the equilibrium of the reaction would favor <span>formation of reactants. One indication would be the gas that is present in the product side. Increasing the pressure would allow the products to react and form the reactants. Hope this helps.</span>
Answer:
His kinetic energy when he runs at that 5 m/s is 750 joules
Explanation:
The given information are;
The mass of, Lance, the runner = 60-kg
The speed by which Lance is running = 5 m/s
The kinetic energy, KE, is given by the relation;
KE = 1/2×m×v²
Where;
m = The mass = 60-kg
v = The instantaneous speed of motion = 5 m/s
The kinetic energy can be found by substituting the values of the variables in the kinetic energy equation as follows;
KE = 1/2 × 60 kg × (5 m/s)² = 750 joules
His kinetic energy when he runs at that 5 m/s is 750 joules.
Answer:
pressure
