Jill and Susan violated safety procedures by not properly listening and/or reading over the instructions to know all the materials, steps, and equipment they need for the lab. Hope this helps!
Convert metres to feet:
343m*3.28f = 1,125.04ft/s
There are 3600 (60 seconds * 60 minutes) seconds in an hour. Therefore, use this number to convert to an hour.
1,125.04ft*3600s = 4,050,144 ft/h
Now, since you asked for miles, convert to miles (5280 ft in a mile):
4,050,144ft/5,280m = 767.072mph
That is your answer! Hope I helped. :)
Answer:
<em>The parent isotope in the given elements is Radium 226.
</em>
Explanation:
The two elements given in the question are radioactive elements radon and Helium which are formed after an Alpha decay happens in the radium 226 to form Radon 222.
Radon has many isotopes out of which here radon 222 is formed which is a noble gas that is odourless colourless but Radioactive. Again in this reaction helium is formed which is again a noble gas and very light in weight.
Precipitation occurs when the product of the ion concentration exceeds the Ksp.
