Answer:
Yes
Explanation:
1 mol of any substance is equal to the avagadro constant
The effects on the concentration of SO3 gas when the
following changes occur after initial equilibrium has been established in this
system (N.C. = no change) by adding a catalyst.
2SO2(g) + O2(g) 2SO3(g) + 46.8 kcal
So that even though there is an addition of catalyst, no
change in reactants or products has occurred because catalyst only provides a
faster pathway for the reaction to occur.
Sustainability is the rate at which a resource depletion reduces the capacity of natural capital to provide the future natural income. As long as the draw down exceeds the rate of replenishment, the amount available will eventually shrink to zero - sustainability is destroyed.
Answer:
6.02 × 10²³ atoms.
Explanation:
According to the Avogadro number, the one mole of any substance have 6.02 × 10²³ atoms.
The number 6.02 × 10²³ is called Avogadro number. it is the number of atoms, ions or molecules in one gram atoms of element, one gram ions of substance or one gram molecules of a compound.
For one mole of magnesium.
24.305 g of Mg = 1 mole of magnesium = 6.02 × 10²³ atoms of magnesium.
Other example includes:
18 g of water = one mole of water = 6.02 × 10²³ molecules of water.
23 g of sodium = one mole of sodium = 6.02 × 10²³ atoms of sodium.
A photon is not in an atom. An electron is in the orbitals, the protons and neutrons are in the nucleus, but the photon is NOT included.<span />
