The gamma-ray emitting technetium-99m (metastable) is widely used for medical diagnostic studies. Several chemical forms are used to image different parts of the body. Technetium is a remarkable corrosion inhibitor for steel, and adding very small amounts can provide excellent protection.
hope that helps you :)
Hi,
The answer is gravity.
The bigger the object is the more are other smaller objects attracted to it. The opposite of gravity is dark energy which keeps objects apart and accelerates expansion of the universe.
Hope this helps.

Answer: 1.0 x 10^-3M
Explanation:
The solution with pH 3 is said to be acidic because pH values less than 7 are regarded as acidic, and will produce hydrogen ions.
Mathematically, pH is expressed as
pH = -log(H+)
where H+ is the concentration of hydrogen ion
So, pH calculations are as follows
3 = -log(H+)
(H+) = Antilog (-3)
(H+) = 0.001M
Place (H+) in standard form
(H+) = 1.0 x 10^-3M
Thus, the value of hydrogen ion (H+) in the solution with pH 3 is 1.0 x 10^-3M
They'd observe any new substances or new color, and temp. that is irreversible.
