Trace amounts of la (lanthanum), 4 = 139, will be investigated by irradiating a 10-g soil sample in a thermal neutron aux of 10 neutrons/cm's for 14 days, and determining the induced holа. if the "la activity was found to be 10 bq 1 hour after the end of the irradiation time, calculate the la concentration in the soil in units of ug org and ppm (parts per million by weight). given: 1) la abundance - 100% (activation) - 96 tua ( la) = 1.7 days

the answer is to check all of them! they all apply well at least i think so!

the body's situation won't change the forces are equal opposit and on the same body

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
