Sodium hydroxide is soluble as shown by the following reaction: NaOH(s) Na+ (aq) + OH(aq)
What is the pow of a 3.0 x 10-3 M NaOH solution?

The net force is 100

08.01 hope this and can i get brainlist? ?

If this is a true or galse then its true but if not then what is the question?

Radon-222 or rn-222 has a half-life of 3.82 days. to determine the fraction of an original sample of rn-222 that remains unchanged after 7.646 days, we calculate the amount of rn-222 remaining after 7.646 days and divide it with the original amount. using 1 gram as a basis and using half-life calculation methods, we can determine that  0.249 or 0.25  grams of rn-222 will remain, and thus the fraction remaining is 0.25 or 1/4.
