Answer:
The activity of a radioactive substance is measured in terms of the number of disintegrations a given radioactive sample undergoes in one second. ... More the active atoms present in the ample, more is the number of disintegrations that happen per second. It depends on the decay constant of the radioactive substance.

3 is correct because the .1 moles of the NO3 will be better option to decrease the solubility of the Silver Nitrate.
Answer:
D
Explanation:
Elements in the same group (vertical columns) have the same number of valence electrons. These elements behave similarly because they will either give up or take the same number of electrons to fill their valence shell. Since potassium has 1 valence electron, it will most likely give up one electron. Out of all of the answer options, the only element that is in the same group as potassium is francium.
Cruising at 35,000 feet in an airliner, straight toward the east,
at 500 miles per hour.
Since your speed is not changing and you're moving in a straight line,
your acceleration is zero.
Answer:
The three laws of Chemical Reaction are .The law of constant proportions. The law of multiple proportions. The law of reciprocal proportions.
A chemical compound is always found to be made up of the same elements combined together in the same fixed proportion by mass.
potassium and chlorine gas ---> chloride.
Hope this helps, have a good day.✌
