To calculate the activity of carbon-14 in becquerels, we need a conversion factor to multiply to the value given above. Base on my research, I found that <span>1 Ci = 3.70x10^10 Bq. We convert as follows:
</span>54.7 μCi = 54.7 x 10^-6 Ci ( 3.70x10^10 Bq / 1 Ci ) = 2.02 x 10^6 Bq
Hope this answers the question. Have a nice day.
PbCl2 and PbCl4
Empirical formula is when the molecular formula is reduced (each element) by the same number until you are unable to do so any further.
CH2O cannot be further reduced, but C3H6O3 can all be divided by 3 making it CH2O (same empirical formula)
Answer:
8.87 * 10^23 molecules of Ne
Explanation:
STP means standard temperature and pressure which is 0 degree Celsius and 1 atm. There's a law that says at STP 1 mole of any gas at occupies 22.4 liters of volume. We are gonna use this to do our conversion.
33.0 L Ne * 1mol Ne/22.4L Ne = 1.47321428571 mol Ne (this is moles of Neon)
Now we know avogadro number says there's 6.022*10^23 molecules in 1 mole of anything so we use this to convert the previously calculated moles of Neon to moleculues.
1.47321428571 mol Ne * 6.022*10^23 molecules/1mol Ne = 8.87 * 10^23 molecules of Ne
Answer:
90% of people marry there 7th grade love. since u have read this, u will be told good news tonight. if u don't pass this on nine comments your worst week starts now this isn't fake. apparently if u copy and paste this on ten comments in the next ten minutes you will have the best day of your life tomorrow. you will either get kissed or asked out in the next 53 minutes someone will say i love you
Explanation:
Ionization refers to the process of losing or gaining electrons. The correct answer is D.
