2. HOW MUCH HEAT IS REQUIRED TO BE RELEASED WHEN
jarptica [38.1K]

Answer: -112200J

Explanation:

The amount of heat (Q) released from an heated substance depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)

Thus, Q = MCΦ

Since,

Q = ?

Mass of water vapour = 30.0g

C = 187 J/ G°C

Φ = (Final temperature - Initial temperature)

= 100°C - 120°C = -20°C

Then apply the formula, Q = MCΦ

Q = 30.0g x 187 J/ G°C x -20°C

Q = -112200J (The negative sign does indicates that heat was released to the surroundings)

Thus, -112200 joules of heat is released when cooling the superheated vapour.

1. The H atom and the Be +3 ion each have one electron. Does the Bohr model predict their spectra accurately? Would you expect t
lesantik [10]

Answer:

yes the Bohr model predicts their spectra accurately

Explanation:

The Bohr model based on one electron system

The atom H  has a single atom and the ion Be+3 has a single atom as well and this proves that the Bohr model predicts their spectra accurately .

also apply the equation model to further explain

E = \frac{-(z^2) (2.18 * 10^{-18}j) }{n^2}

z = atomic number

for H the value of z = 1

for Be+3 the value of z = 4

when this values are substituted into the equation above

E =  \frac{-(1) (2.18 * 10^{-18}j) }{n^2} ,   E = \frac{-(4) (2.18 * 10^{-18}j) }{n^2}

this results show that the energy  level of Be+3 is higher than the energy level of H by a factor of 16 , and this shows that their line patterns are similar
