Q2. A sample of pure Mg(NO3)2 was decomposed by heating as shown in the equation below.
Give yo
The ga:
(a)
2Mg(NO3)2(s) - 2MgO(s) + 4NO2(g) + O2(g)
A 3.74 x 10-2 g sample of Mg(NO3)2 was completely decomposed by
heating
Calculate the total volume, in cm, of gas produced at 60.0 °C and 100 kPa.
Give your answer to the appropriate number of significant figures.
The gas constant R= 8.31 J K-mol-1.

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.

hope it
