What is required for electrons to move from the stable energy level to an excited state?

answer

When an electron temporarily occupies an energy state greater than its ground state, it is in an excited state. An electron can become excited if it is given extra energy, such as if it absorbs a photon, or packet of light, or collides with a nearby atom or particle

What was done to the linear parent function, f(x) = x, to get the function<br>g(x) = 1/6 x​
s2008m [1.1K]

Answer:

Vertically Shrunk by a factor of 1/6

Explanation:

Parent Formula: f(x) = a(bx - c) + d

<em>a</em> - vertical shrink/stretch and x-reflections

<em>b</em> - horizontal shrink/stretch and y-reflections

<em>c</em> - horizontal movement left/right

<em>d</em> - vertical movement up/down

Since we are only modifying <em>a</em>, we are dealing with vertical shrink/stretch:

Since a < 1 (1/6 < 1), we are dealing with a vertical shrink of 1/6.

Since a > 0 (1/6 > 0), we do not have a reflection over the x-axis.

A student uses a calorimeter to determine the enthalpy of dissolving for ammonium nitrate. The student fills a calorimeter with
ale4655 [162]
Enthalpy change during the dissolution process = m c ΔT,

here, m = total mass = 475 + 125 = 600 g
c = <span>specific heat of water = 4.18 J/g °C
</span>ΔT = 7.8 - 24 = -16.2 oc (negative sign indicates that temp. has decreases)
<span>
Therefore, </span>Enthalpy change during the dissolution = 600 x 4.18 X (-16.2)
                                                                                 = -40630 kJ
(Negative sign indicates that process is endothermic in nature i.e. heat is taken by the system)

Thus, <span>enthalpy of dissolving of the ammonium nitrate is -40630 J/g</span>

A piece if stone has a mass of 24.595 grams and a volume of 5.34 cm ^3. What is the density of the stone
Rudik [331]

Answer:

The answer is

<h2>4.61 g/cm³</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume}  \\

From the question

mass of stone = 24.595 g

volume = 5.34 cm³

The density of the stone is

density =  \frac{24.595}{5.34}  \\  = 4.605805243...

We have the final answer as

<h3>4.61 g/cm³</h3>

Hope this helps you
