Answer:
Meteoroids are tiny asteroids or the broken-off crumbs of comets and sometimes planets. They range in size from a grain of sand to boulders 3 feet (1 meter) wide. When meteoroids collide with a planet's atmosphere, they become meteors
pls give me brainliest lol :)
Mass is the physical property of matter can be expressed numerically in SI units.
Answer:
(A) The statement is false. The starting material is favored at equilibrium
Explanation:
As we know that type of reaction is predicted by value Gibbs free energy.
ΔG >0 It means that reaction is non spontaneous and favors the reactant of the reaction.
ΔG <0 It means that reaction is spontaneous and favors the product of the reaction.
As we know that
ΔG = ΔH -T ΔS
Here given that Assume the entropy term is small compared to the enthalpy term so ΔS = 0
⇒ ΔG = ΔH
Given that
ΔH o = 65 kJ/mol,
ΔG = ΔH = 65 kJ/mol
ΔG >0 It means that reaction is non spontaneous and favors the reactant of the reaction.
So the option A is correct.
(A) The statement is false. The starting material is favored at equilibrium.
Answer:After the hydrogen in the star's core is exhausted, the star can fuse helium to form progressively heavier elements, carbon and oxygen and so on, until iron and nickel are formed. ... Supernova explosions result when the cores of massive stars have exhausted their fuel supplies and burned everything into iron and nickel.
