Hydrochloric a strong acid where as formic acid is a weak one why? ​

Chemistry
1 answer:
stiks02 [169]3 years ago
4 0

Explanation:

it varies due to ph difference

Hcl or hydrochloric acid has a very low ph (about 1) and formic acid has a higher 1

the lower the ph the more acidic and corrosive it making it stronger

hope this helps

Arturiano [62]

Answer:

See explanation

Explanation:

The reaction between formic acid and potassium hydroxide is an acid base reaction.

Remember that an acid base reaction yields salt and water only.

If you look at the curved arrow mechanism shown, you will discover that the hydroxide ion from KOH abstracts a proton from the acid to yield potassium formate and water

In a reaction, 5.3g of Sodium Carbonate reacted with 6g of ethanoic acid. The products were 2.2g of CO2, 0.9g of water and 8.2g
V125BC [204]

SOLUTION :

Law of conservation of Mass States that "Mass is neither created, nor destroyed".

→ Like Mass of Reactants = Mass of products.

REACTANTS :

  • Mass of Sodium Carbonate(given) = 5.3g

  • Mass of ethanoic acid(given)= 6g

The total mass of reactants:

= 5.3 + 6

= 11.3g

<h3>•Products are :</h3>

  • Mass of Carbon Dioxide = 2.2g

  • Mass of Water = 0.9g

  • Mass of Sodium ethanoate = 8.2g

The total mass of products is :

= 2.2 + 0.9 + 8.2

= 3.1 + 8.2

= 11.3g

Hence the, Mass of Reactants = Mass of products

∴ The given reaction is in agreement with the law of conservation.

The volume of a gas is proportional to number of moles of a gas is known as
Kay [80]

Answer:

A modern statement is: Avogadro's law states that, "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules." For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are constant.

A backpacker collects snow at 0°C, and places it in a cooking pot on a camp stove. It takes 643 kJ of heat energy to melt the sn
frutty [35]

Answer:

mass (m) of the snow that the backpacker collected= 0.855 kg

Explanation:

Given that:

Q = 643 kJ = 643000 J

ΔHfusion = 6.02 kJ/mol = 6020 J/mol

number of mole of water H2O = \frac{mass (m)}{18}

c = 4.18 J/g⋅K

ΔT = 100 K

Since there is a phase change from solid to liquid; then :

Q = Q_s + Q_l

ΔH = \frac{q}{mol}

However without the given mass; we substitute \frac{m}{18} for the number of moles; so:

Q = \delta H * \frac{m}{18} + m*c * \delta T

643000 =6020 * \frac{m}{18}+ m * 4.18 * 100

m = 855 g

m = 0.855 kg

mass (m) of the snow that the backpacker collected= 0.855 kg
