<h2>Answer:</h2><h3>1. both</h3>

An electron in an excited state can release energy and 'fall' to a lower state. When it does, the electron releases a photon of electromagnetic energy. When the electron returns to the ground state, it can no longer release energy but can absorb quanta of energy and move up to excitation states (higher orbitals).

<h3>2. One electron</h3>

An electron will move to the orbital with lowest energy. Each orbital can hold only one electron pair. Electrons will separate as much as possible within a shell.

A sample of iron metal absorbs 4.56j of heat, upon which temperature of the sample increased from 29 degrees c to 36 degrees c.
solmaris [256]

Answer:

Mass = 1.42 g

Explanation:

Given data:

Amount of heat absorbed = 4.56 j

Initial temperature = 29°C

Final temperature = 36°C

Mass of iron metal = ?

Specific heat capacity of iron = 0.46 j/g.°C

Solution:

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

ΔT = T2 - T1

ΔT = 36°C - 29°C

ΔT = 7°C

Q = m.c. ΔT

m = Q / c. ΔT

m = 4.56 j / 0.46 j/g°C . 7°C

m = 4.56 j /3.22 j/g

m = 1.42 g

Równania reakcji chemicznej
Aliun [14]

Answer:

Reakcja chemiczna jest opisana równaniem chemicznym, wyrażeniem określającym tożsamość i ilość substancji biorących udział w reakcji. Równanie chemiczne pokazuje początkowy związek (związki) - reagenty - po lewej stronie, a końcowy związek (związki) - produkty - po prawej stronie, oddzielone strzałką.
