Answer:
[O2(g)][SO2(g)]^2/[SO3(g)]^2
There are many kinds of pyroclastic material ejected during a volcanic eruption. Ash is the most common pyroclastic rock material ejected during an eruption. Volcanic ash is so fine that it can be blown into the atmosphere and picked up by the jet stream where it can circle the Earth for several years.
Density= mass/volume. volume= 12 x 6 x 10. 415/720=.57g/cm^3
Answer:
time taken to cook on the pressure cooker = 100 seconds = 1.67 mins
Explanation:
B) 40%
The balanced equation indicates that for every 3 moles of H2 used, 2 moles of NH3 will be produced. So the reaction if it had 100% yield would produce (2.00 / 3) * 2 = 1.333333333 moles of NH3. But only 0.54 moles were produced. So the percent yield is 0.54 / 1.3333 = 0.405 = 40.5%. This is a close enough match to option "b" to be considered correct.
