Fluorine is a toxic, reactive gas. Witch representation (structural formula, electron dot structure, or three-dimensional model)

svp [43]

Answer: We will use the electron-dot structure to tell the reactivity of fluorine.

Explanation: Fluorine atom is the 9th element of the periodic table.

Atomic number: 9

Electronic configuration of fluorine = $1s^22s^22p^5$

The number of valence electrons = 7

and the valency for this element = 1 (because this element requires only one electron to have a stable electronic configuration)

Electron dot structures are the structures which represent the valence electrons present around the nucleus of an atom. The dots in the structures represent the electrons.

Reactivity of an element is defined as its ability to gain or loose electrons easily.

As fluorine atom gains 1 electron easily, so it is very reactive.

Electron dot structure of fluorine atom is given in the image attached.

If you want to change the pitch of a sound, you have to change the ___

aleksandrvk [35]

Answer: If you want to change the pitch of a sound, you have to change the <em>frequency.</em>

Explanation:

Pitch is the quality of the sound to judge it has higher or lower.The frequency of the sound wave is perceived as pitch.Pitch and frequency of the sound are related to each other

If want to increase the pitch we have to increase the frequency of the sound.
If want to decrease the pitch we have to decrease the frequency of the sound.

If you want to change the pitch of a sound, you have to change the <em>frequency.</em>

Aqueous hydrochloric acid will react with solid sodium hydroxide to produce aqueous sodium chloride and liquid water . Suppose 1

blsea [12.9K]

Answer: The maximum amount of water that can be produced is 0.74 g

Explanation:

To calculate the number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$ .....(1)

Putting values in equation 1, we get:

$\text{Moles of hydrochloric acid:}=\frac{1.5g}{36.5g/mol}=0.041mol$

$\text{Moles of sodium hydroxide}=\frac{2.67g}{40g/mol}=0.067mol$

The chemical equation for the reaction is

$HCl+NaOH\rightarrow NaCl+H_2O$

By Stoichiometry of the reaction:

1 mole of HCl reacts with 1 mole of NaOH

So, 0.041 moles of HCl will react with = $\frac{1}{1}\times 0.041=0.041mol$ of NaOH

As, given amount of NaOH is more than the required amount. So, it is considered as an excess reagent. Thus, HCl is considered as a limiting reagent because it limits the formation of product.

By Stoichiometry of the reaction:

1 mole of HCl produces = 1 mole of water

So, 0.041 moles of HCl will produce = $\frac{1}{1}\times 0.041=0.041moles$ of water

Mass of water= $moles\times {\text{Molar Mass}}=0.041mol\times 18g/mol=0.74g$

Thus the maximum amount of water that can be produced is 0.74 g
