How would Lithium gain full valence levels

Lubov Fominskaja [6]

Answer:

In order to have a full outer shell atoms can GAIN or LOSE electrons. Atoms with very few VALENCE electrons, such as Lithium, would need to gain many electrons for a full shell so it is easier for them to LOSE electrons and become POSITIVE.

Explanation:

What is the force that holds atoms together

ololo11 [35]

Explanation:

Chemical bond refers to the forces holding atoms together to form molecules and solids. This force is of an electric nature, and the attraction between electrons of one atom to the nucleus of another atom contributes to what is known as chemical bonds.

6) (a) Calculate the absorbance of the solution if its concentration is 0.0278 M and its molar extinction coefficient is 35.9 L/

Anvisha [2.4K]

Answer:

6) (a) 0.499; (b) 31.7 %

7) 0.15

Explanation:

6) (a) Absorbance

Beer's Law is

$A = \epsilon cl\\A = \text{35.9 L&\cdot$mol$^{-1}$cm$^{-1}$} $\times$ 0.0278 mol$\cdot$L$^{-1} \times $ 0.5 cm = \mathbf{0.499}$

(b) Percent transmission

$A = \log {\left (\dfrac{1}{T}}\right)}\\\\\%T = 100T\\\\T = \dfrac{\%T}{100}\\\\\dfrac{1}{T} = \dfrac{100 }{\%T}\\\\A = \log \left(\dfrac{100 }{\%T} \right ) = 2 - \log \%T\\\\0.499 = 2 - \log \%T\\\\\log \%T = 2 - 0.499 = 1.501\\\\\%T = 10^{1.501} = \mathbf{31.7}$

7) Absorbance

$A = \log \left (\dfrac{I_{0}}{I} \right ) = \log \left (\dfrac{I_{0}}{0.70I_{0}} \right ) = \log \left (\dfrac{1}{0.70} \right ) = -\log(0.70) = \mathbf{0.15}}$

1. When an acid reacts with a base, what compounds are formed? (1 point) a salt only water only metal oxides only a salt and wat

scoundrel [369]

Answer: 1) only a salt and water

An acid and base reacts together to undergo neutralization to form salt and water.

$HCl+NaOH\rightarrow NaCl+H_2O$

where HCl is an acid and NaOH is a base to form salt (NaCl) and water $(H_2O)$ .

Answer: 2) The formula of the hydrogen ion is often written as $H^+$ .

All acids dissociate in water to give $H^+$ ions.

Answer: 3) Arrhenius acids are substances that ionizes to yield protons in aqueous solution.

$HCl\rightarrow H^++Cl^-$

Arrhenius bases are substance that ionizes to yield hydroxide ions in aqueous solution.

$NaOH\rightarrow Na^++OH^-$

Answer: 4) A conjugate acid base pair transfers hydrogen ion.

$CH_3COO^-+H_2O\rightarrow CH_3COOH+H_3O^+$

Here $CH_3COO^-$ accepts a proton and thus act as a base and the corresponding $CH_3COOH$ is its conjugate acid.

Answer: 5) Bronsted Lowry acid is a substance that donates protons. Bronsted Lowry base is a substance that accepts protons.

$NH_4^+$ and $NH_3$

$NH_3+H^+\rightarrow NH_4^+$

$NH_3$ is a acid which accepts proton and thus acts as base to form conjugate acid $NH_4^+$ .

Why is Potassium not used in school laboratory

densk [106]

<h3>Because it is harmful for school environment.</h3>

Potassium Metal Is Explosive— Do Not Use It! The reaction of sodium with water is a spectacular and essential classroom demonstration. Many teachers want to show also the more violent reaction of potassium. We propose not to do so because explosions can happen even before the metal is in contact with water.
