Considering the chart shown, at what temperature does the substance boil? 200ºC 1,200ºC 2,200ºC 2,400ºC
kodGreya [7K]

Answer:

The answer is 2,200ºC

Explanation:
I took the assignment for Edge, I don't think I can send the image because it might pick up on that and get reported, sorry!

The only other rationale that I have is that it's boiling because the graph shows that it's at a constant temperature/rate at 2,200ºC for quite a while. Typically when something boils, it stays at that constant rate of boiling, unless you turn the temperature up or it's finally able to peak..?

Which two mantle hot spots are located at mid-ocean<br> ridges?
Darya [45]

Answer:

This region of thick, hot crust and mantle extends 1,300 kilometers north and south of the Iceland hotspot and some 1,000 kilometers north and south of the Azores hotspot. Together, the two hotspots appear to be feeding a huge supply of magma to nearly the entire northern segment of the Mid-Atlantic Ridge.

Describe how an acidic solution forms when HCHIS
kakasveta [241]
The presence of H3O+ is the hydronium ion, and one definition of an acid is something that donates a proton (H+). HCl in this case does just that. Basic solution forming with NaOH and water: ... NaOH + H2O ==>Na+ + OH- so it donates or produces OH- ions, thus making a basic solution

Part A: How many moles of NH3 can be produced from 21.0 mol of H2 and excess N2?
Lorico [155]

Answer:

a) 7.0 moles of NH3

b) 61.2 g of NH3

c) 4.15 g of H2

d) 8.9 ×10^19 molecules

Explanation:

Equation of the reaction;

N2(g) + 3H2(g) ⇄NH3(g)

a)

If 3 moles of H2 yields 1 mole of NH3

21 moles of H2 will yield 21 × 1 /3 = 7.0 moles of NH3

b)

1 mole of N2 yields 17 g of NH3

3.6 moles of N2 yields 3.6 moles × 17 g of NH3 = 61.2 g of NH3

c)

If 6g of H2 produces 17 g of NH3

xg of H2 will produce 11.76 g of NH3

x= 6 × 11.76/17

x= 4.15 g of H2

d)

If 6g of hydrogen yields 6.02 × 10^23 molecules of NH3

8.86 × 10^-4g of H2 yields 8.86 × 10^-4g × 6.02 × 10^23 /6 = 8.9 ×10^19 molecules
