Answer:
Natural nuclear disintegration.

But it is nuclear because helium decays to release an energy particle (Beta particle).
Dissolving is your answer to this question. Becuase when something dissolves it is no longer in the same shape or state cause if something dissovles then goes away into another state.
Answer:
0.1 M weak acid
Explanation:
The term pH simply means power of hydrogen which is basically a log (the exponent to base 10 of the concentration) of the concentration of the hydrogen ions.
Weak acids have a higher pH since their hydrogen concentration is lower than that of strong acids.
Answer:
It's important that we understand how the climate is changing so that we can prepare for the future. Studying the climate helps us predict how much rain the next winter might bring, or how far sea levels will rise due to warmer sea temperatures.
Weather is the state of the atmosphere at any given time and place.
Climate is the long-term average of the weather in a given place
