Answer:

The change in entropy is negative; -ΔS

Explanation:

The entropy of a system measures the degree of randomness or energy dispersal of the system. The symbol for entropy is S.

For a given system, the change in entropy is symbolized as ΔS.

For an increase in entropy of a system, the final entropy must be greater than the initial entropy  i.e. Δfinal > Δinitial. Therefore ΔS > 0

For a decrease in entropy of a system, the final entropy must be less than the initial entropy  i.e. Δfinal < Δinitial. Therefore ΔS < 0 or ΔS is negative

A system with decreasing entropy may have a positive or negative free energy change, ΔG.

Also, a system with decreasing entropy may have a positive or negative enthalpy change, ΔH.

How many moles of Magnesium Oxide are in 35g?
irga5000 [103]

Answer:

0.88mol

Explanation:

The number of moles, n, contained in a substance can be calculated using the formula;

Moles (n) = mass (m) ÷ molar mass (MM)

Molar mass of Magnesium oxide (MgO) = 24 + 16

= 40g/mol

According to the question, Mass of MgO = 35grams

Mole = 35/40

Mole = 0.875

Mole = 0.88mol

1. The red light associated with the aurora borealis is emitted by excited oxygen atoms. This
stiv31 [10]

Answer:

Frequency = 0.005× 10¹⁷ s⁻¹

E =  0.03 × 10⁻²⁰KJ

Explanation:

Given data:

Wavelength of light = 630.0 nm (630 × 10⁻⁹ m)

Frequency of light = ?

Energy in joule = ?

Solution:

speed of light = wavelength × frequency

Frequency = speed of light /  wavelength

Frequency = 3 × 10⁸ m/s / 630 × 10⁻⁹ m

Frequency = 0.005× 10¹⁷ s⁻¹

Energy:

E = h. f

E = 6.63× 10⁻³⁴ Kg. m²/s × 0.005× 10¹⁷ s⁻¹

E = 0.03 × 10⁻¹⁷ j

E = 0.03 × 10⁻¹⁷ j×1 kj /1000 j

E =  0.03 × 10⁻²⁰KJ
