It is Iridium or Ir-31 is the closest answer I could find for you. The actual Iridium used is Ir-192.
Another problem was that Uranium/U is not the one used its Radium so that can not be it.
And Europium is used for helping with curing brain tumors but only in trace amounts

An aqueous solution of 1.29 M ethanol, CH3CH2OH, has a density of 0.988 g/mL. The percent by mass of CH3CH2OH in the solution is

anzhelika [568]

Answer:

Explanation:

Hello, for this case, we assume that the volume of the solution is 1L, thus, the mass is given by using the density as follows:

$m_{solution}=1L*\frac{1000 mL}{1L}*\frac{0.988g}{1mL} =988g$

Now, the mass of the ethanol:

$m_{C_2H_5OH}=(1.29molC_2H_5OH/L*1L)*\frac{46gC_2H_5OH}{1molC_2H_5OH} \\m_{C_2H_5OH}=59.34g$

Finally, the by mass percent is:

$m/m=\frac{59.34g}{988g}*100\\$ %

%m=6%

Best regards.

Some areas of the Earth receive more solar radiation than others. Which of the following results from the Sun's uneven heating o

STatiana [176]

Some areas of the Earth receive more solar radiation than others and this Sun’s uneven heating of the Earth result in 

i. Climate

ii. Weather

iii. Ocean currents

Further Explanations:

Earth receives varied amount of solar radiation in its different parts. The situation is due to the orbicular shape of the Earth and inclination of the sun during different time of the year. We can see one such example that, during June sun is overheard Tropic of cancer and during September it is overhead Tropic of Capricorn. Because of the inclination,different regions of the Earth experience different climate at the same span of time. This unevenness results in the following phenomenon:

i. Climate:Climate is a continuing average weather condition of a place. Some of the climatological variables commonly measured to determine the climate temperature, moistness, atmospheric pressure, current of air, and precipitation.

ii. Weather: It is defined as the state of atmosphere, describing the degree of heat or coldness, wetness or aridness, calm or stormy. It also refers to daily temperature and rainfall activities.

iii. Ocean Current: It is more or less perpetual or continuous engaged movement of oceanic water flowing on the Earth’s oceans. The current gets created as the resultant of geological forces acting on the oceanic surface.

Which event is most likely an example of a chemical reaction

Inessa [10]

Explanation:

One example of a chemical reaction is the rusting of a steel garbage can. That rusting happens because the iron (Fe) in the metal combines with oxygen (O2) in the atmosphere. Chemical bonds are created and destroyed to finally make iron oxide (Fe2O3).
