C the South Pole gets 24 hours of daylight
Answer:
1) Activation energy ( A )
2) Molar concentration of XZ(g) ( C )
Explanation:
XZ(g) ⇄ 2XZ
1) <em>Activation energy </em><em>I</em>s decreased by the addition of a catalyst
while Equilibrium constant will Increase and other options will still remain unaffected
2)<em>Molar concentration of X</em><em>Z</em><em>(g) </em>Is deceased when the volume of the reaction vessel is increased and equilibrium is reestablished at 298 K
while Number of molecules present will Increase
Using the ideal gas equation:
PV = nRT, we can form:
V/n = constant
Thus,
V₁/n₁ = V₂/n₂
n₂ = 2.3 x 85.5/50.5
= 3.89 moles
2H2+O2=2H2O
This is the chemical formula for water. Hope this helps.
Answer:
The correct statement is option c, that is, particles discharged in the air by volcanoes fall to the ground and enrich the soil.
Explanation:
The eruptions of volcanoes lead to the dispersion of ash over the broader regions surrounding the site of eruption. On the basis of the chemistry of the magma, the ash will be comprising different concentrations of soil nutrients. While the major elements found in the magma are oxygen and silica, the eruptions also lead to the discharging of carbon dioxide, water, hydrogen sulfide, sulfur dioxide, and hydrogen chloride.
In supplementation, the eruptions also discharge bits of rocks like pyroxene, potolivine, amphibole, feldspar that are in turn enriched with magnesium, iron, and potassium. As an outcome, the areas which comprise huge deposits of the volcanic soil are quite fertile.
