Answer

C. It becomes plutonium-239

Explanation

Absorption of a neutron in the uranium-238 nucleus yields uranium-239, which decays after 23.47 minutes through electron emission into neptunium-239 and ultimately, after 2.356 days, into plutonium-239.

Does the shape, size, or temperature of matter affect its density?
aleksley [76]
Shape and size doesn't affect the density of an object but temperature does affect the density of an object because the molecules act differently in different temps.

1. How many liters of Co, gas are produced from 3.5 moles of 02​
Pavel [41]

The Equation of reaction

C + O2 === CO2

First Blank spot would be

---- 3.5moles of O2

2nd spot

Up.... 1mole of CO2

Down ---- 2moles of Oxygen atoms

3rd spot

Up... --- 22.4L of CO2(1mole of any gas at STP contains 22.4L)

Down---- 1mole of CO2

Final answer --- 3.5 x 1/2 x 22.4

=39.2L of CO2

Describe the formation of an aqueous KI solution when KI dissolves in water
Sidana [21]
Potassium Iodide or KI is an ionic compound and dissolves to water since the two are polar substances. Like dissolves like. As KI is dissolved into water, the KI molecules dissociates into ions, the K+ and I- ions. Water molecules can stabilize these ions. The K+ ions attracts the negative side of H2O molecules which is the oxygen side while the I- ions attracts the positive side of H2O molecules or the hydrogen side.

From the diagram, when the temperatures of reactants are raised from 20°C to 30°C:
sveta [45]

Answer: D. The number of molecules having Er or greater doubles.

Explanation: As the temperature increases from 20°C to 30°C, the number of molecules with maximum energy decreases, but the number of effective collisions which result into the formation of product doubles.

This is due to doubling of molecules which  possess energy equal to or greater than E_r which means now double number of molecules will be able to cross the energy barrier and hence the formation of product increases and hence the rate increases to double.
