Why does a salt compound give off light (or a colored flame) when burned? 4. did lithium chloride and sodium chloride give off s
Free_Kalibri [48]

3) Answer is: because elements have different emmision spectrum.

Emission spectrum of a chemical element is the spectrum of frequencies emitted due to an atom making a transition from a high energy state to a lower energy state. Each element's emission spectrum is unique.

4) Answer is: lithium chloride and sodium chloride do not have similar colors.

Lithium ion has red and sodium ion has yellow emission spectrum.

5) Answer is: because metals have valence electrons in different energy shells.

Each transition has a specific energy difference.

6) Answer is: salts of alkaline and earth alkaline metals.

For example barium chloride gives green light.

In a roller coaster, both the kinetic and potential energy in the car decreases at
Lemur [1.5K]

We can confirm that in a roller coaster, kinetic and potential energy in the car decreases at  each successive hill because of  the force of gravity which converts potential  energy into  kinetic energy.

<h3>What are potential and kinetic energy?</h3>
  • Potential energy is referred to as <em><u>positional energy</u></em>.
  • This means that the object in question gains energy based on its position relative to others.
  • Kinetic energy is the energy of movement.
  • Gravity causes the roller coaster to fall, losing potential energy.
  • This causes it to gain all of the potential energy as kinetic energy.
  • Once at the bottom, the coaster no longer moves and thus loses the kinetic energy as well.

Therefore, we can confirm that gravity is the force that causes the shift from potential energy to kinetic energy and thus causes them both to decrease after each successful hill in the roller coaster.

The reaction below shows how silver chloride can be synthesized. AgNO3 NaCl Right arrow. NaNO3 AgCl How many moles of silver chl
Otrada [13]

From 15 mol of Silver nitrate, the moles of silver chloride produced have been 15 mol. Thus, option B is correct.

The balanced chemical reaction for the synthesis of silver chloride has been:

\rm AgNO_3\;+\;NaCl\;\rightarrow\;AgCl\;+\;NaNO_3

From the balanced equation, since there has presence equal moles of silver nitrate and sodium chloride, the moles of silver chloride formed has been equivalent. Thus, 1 mole of silver nitrate gives 1 mole of silver chloride.

The moles of silver nitrate available are,  \rm M_A_g_N_O_3=15\;mol

The moles of silver nitrate produced can be given as:

\rm 1\;mol\;AgNO_3=1\;mol\;AgCl\\15\;mol\;AgNO_3=15\;\times\;1\;mol\;AgCl\\15\;mol\;AgNO_3=15\;mol\;AgCl

Thus, the moles of silver chloride produced have been 15 mol. Thus, option B is correct.
