Help pls!! For the reaction H CI + NaOH -> NaCI + H2O, if 10 moles of NaOH react, how many moles of NaCI are made?

The air is going to come out because of the low pressure.

I'm sorry but i'm only grade

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.

Hello there,it will only be somewhat eroded (25%)hope this : ))~top
