Answer : The correct option is, Bases.

Explanation :

Acids : It is a substance that has ability of donating proton or hydrogen ion, $H^+$ .

Bases : It is a substance that has ability of donating hydroxide ion, $OH^-$ .

Salts : It is an ionic compound that contain positively charged ions and negatively charged ions. The salt is formed when an acid react with a base in equal proportions.

Neutral compound : It is a compound that is formed by the combination of strong acid and strong base or weak acid and weak base.

As per question, KOH and LiOH are the examples of bases because they have ability of donating hydroxide ion, $OH^-$ . KOH and LiOH are the strong base that are completely dissociate.

$KOH\rightarrow K^++OH^-$

$LiOH\rightarrow Li^++OH^-$

Hence, the correct option is, Bases.

5) Determine the mass if lithium hydroxide that is produced when 12.87 g of lithium

netineya [11]

Answer: 26.54 grams

Explanation:

To calculate the moles :

$\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}$

$\text{Moles of lithium nitride}=\frac{12.87g}{34.83g/mol}=0.369moles$

$Li_3N+3H_2O\rightarrow 3LiOH+NH_3$

$Li_3N$ is the limiting reagent as it limits the formation of product and $H_2O$ is the excess reagent

According to stoichiometry :

As 1 moles of $Li_3N$ give = 3 moles of $LiOH$

Thus 0.369 moles of $O_2$ give = $\frac{3}{1}\times 0.369=1.108moles$ of $LiOH$

Mass of $LiOH=moles\times {\text {Molar mass}}=1.108moles\times 23.95g/mol=26.54g$

Thus 26.54 g of $LiOH$ will be produced from the given mass.

Does someone know the combustion in a jacket potato???

Leya [2.2K]

Answer:

Some varieties of potato, such as Russet and King Edward, are more suitable for baking than others, owing to their size and consistency. Despite the popular misconception that potatoes are fattening, baked potatoes can be part of a healthy diet.[2]

What is the boiling point of a solution of 76 g of water dissolved in 500 mL of acetic acid, CH3COOH?

tatuchka [14]

Answer:

127.3° C, (This is not a choice)

Explanation:

This is about the colligative property of boiling point.

ΔT = Kb . m . i

Where:

ΔT = T° boling of solution - T° boiling of pure solvent

Kb = Boiling constant

m = molal (mol/kg)

i = Van't Hoff factor (number of particles dissolved in solution)

Water is not a ionic compound, but we assume that i = 2

H₂O → H⁺ + OH⁻

T° boling of solution - 118.1°C = 0.52°C . m . 2

Mass of solvent = Solvent volume / Solvent density

Mass of solvent = 500 mL / 1.049g/mL → 476.6 g

Mol of water are mass / molar mass

76 g / 18g/m = 4.22 moles

These moles are in 476.6 g

Mol / kg = molal → 4.22 m / 0.4766 kg = 8.85 m

T° boling of solution = 0.52°C . 8.85 m . 2 + 118.1°C = 127.3°C

Answer:

because the number of constitutional confirmation , and geometric isomers goes up with each carbon atom added there are many more possible configurations and connectivities possible with decane , a 10 carbon chain , than with butane, a 4 carbon chain
