Answer: d. 22.4 L
Explanation:
According to Avogadro's law , 1 mole of every gas occupies 22.4 L of volume at STP.
moles of ammonia=
Given: Hydrogen is the excess reagent and nitrogen is the limiting reagent as it limits the formation of product.
From the given balanced equation:
2 moles of ammonia is produced by 1 mole of nitrogen.
Thus 2 moles of ammonia is produced by 22.4 L of nitrogen at STP as 1 mole of nitrogen occupies 22.4 L at STP.
Explanation:
Geological activity determines geological structures. The prevalent types and forms of tectonic working in a place will control the form of structure that can be found in a terrain.
- In volcanic region, it is common to see volcanic structures of different types such as calderas, strato-volcano etc. These structures are formed by the volcanic activities.
- Also, in a karst topography, we find sink holes, stalactites and stalagmites etc. due to the nature of the geologic activities going on.
- Some sedimentary rocks shows cross bedding due to the environment where they form.
So, geologic activities controls the structure found in an area
Answer:
Explanation:
The law of multiple proportions say that two elements, A and B, are able to combine with each other to form distinct compounds, the different masses of B that bind to a certain mass of A, are in relation of integers and simple numbers.
2SO₂ → S₂ + 2O₂
Mass S₂=2 . 32g= 64g
Mass 2O₂=4 . 16g=64g
∴ 64/64=1 ⇒ One produced 1.002 g S for every gram of O, the relation is 1:1
2SO₃ → S₂ + 3O₂
Mass S₂=2 . 32g= 64g
Mass 3O₂=6 . 16g=96g
∴ 64/96= 2/3 ⇒ It is produced 0.668 g S for every gram of O, the relation is 2:3.
To sum up, these results are consistent with the law of multiple proportions because the results are integers and simple numbers.

The reaction C₂H₆+137kJ→C₂H₄+H₂ is endothermic since the energy is being absorbed by the reaction and not released. We know this by the fact that the energy is on the reactants side of the reaction. If the energy was on the products side of the reaction we would call it exothermic since energy would be being released. Since this reaction is endothermic we know that the products will have more energy than the reactants which means that the answer is B.
(the equation in the question does not have an arrow in it so I assumed it was between the 137kJ and C₂H₄).
I hope this helps. Let me know if anything is unclear.
