The answer is acidity, because pH indicators help indicate the H+ or OH- concentration in a solution. H+ concentrations create acids, and OH- make bases. pH indicators don’t indicate any of the other answers in the question, so the answer is Acidity.
The law is Newton's first law or called the law of inertia; Which just means that an object at rest stays at rest and an object in motion stays in motion and continues at the same speed and in the same direction unless acted upon by an outside force force.
Answer:
If a substance can be dissolved it is called soluble.
if a substance cannot be dissolved it is called insoluble
Answer:
4202.1 K
Explanation:
From;
PV=nRT
P= pressure of the gas = 18.5 bar
V = volume of the gas = 115L
n= number of moles of the gas = 6.1 mole
T= temperature of the gas = ?
R = gas constant = 0.083 L⋅bar⋅K−1⋅mol−1
T = PV/nR
T = 18.5 * 115/6.1 * 0.083
T = 2127.5/0.5063
T= 4202.1 K
False, it’s not mechanical energy it’s thermal energy.
