I think it is to help with plant growth, and converting nitrogen to ammonia.
Answer:
Li (s) + H₂O (l) → 1/2 H₂ (g) + LiOH (aq)
Explanation:
Lithium metal reacts with liquid water to form hydrogen gas and aqueous lithium hydroxide
2Li (s) + 2H₂O (l) → H₂ (g) + 2LiOH (aq)
We can divide stoichiometry coefficients /2, to have the lowest stoichiometry.
As we know that 760 mmHg is equal to 1 atm.
So,
If 760 mmHg is equal to = 1 atm
Then
738 mmHg will be equal to = X atm
Solving for X,
X = (738 mmHg × 1 atm) ÷ 760 mmHg
X = 0.971 atm
Result:
738 mmHg is equal to 0.971 atm.
Answer:
C.It remains at rest or moves at constant speed in the same direction.
Explanation:
First, remember the Newton's 1st law of motion which states that the object at rest will remain at rest and that in motion will stay in motion with the same speed and same direction unless acted by unbalance forces.
Balanced forces on an object occur when two forces at act on an object are equal in size and act in opposite direction. In this case, a stationary object will stay at rest while an object moving will continue to move at the same speed and same direction.
An object acted by balanced forces is said to be at equilibrium, thus the state of motion will be maintained.The object will not accelerate. A good example of an object acted by balanced forces is an object at rest or in constant motion such as a car that stopped at red-light signal or a car travelling at a constant speed.
