What did you observe in the reaction of phosphoric acid with the freshly cleaned zinc when compared with a piece just taken out

Answer:

The classification is mentioned below for the particular topic.

Explanation:

Whether we position 2 different beakers in such a single beaker through one clean edge of zinc-containing H₃Po₄ and another one with unflushed zinc.

The zinc that was washed set to release hydrogen gas way quicker, unlike unventilated zinc.

⇒ $3Zn+2H_{3}Po_{4}\rightarrow Zn_{3}(Po_{4})_{2}+3H_{2}$

Since fresh zinc complicates the cycle since, as a comparison to polluted zinc, there was little contact with either the reaction.

The pK of acetic acid is pK = 4.76. For a 0.1 M solution of acetic acid at a pH = 4.76 what is the concentration of [H+]?

spin [16.1K]

Answer:

[H+] = 1.74 x 10⁻⁵

Explanation:

By definition pH = -log [H+]

Therefore, given the pH, all we have to do is solve algebraically for [H+] :

[H+] = antilog ( -pH ) = 10^-4.76 = 1.74 x 10⁻⁵

How are the conditions at which phases are in equilibrium represented on a phase diagram?

How are the conditions at which phases are in equilibrium represented on a phase diagram?

Image result for How are the conditions at which phases are in equilibrium represented on a phase diagram?

Along the line between liquid and solid, the melting temperatures for different pressures can be found. The junction of the three curves, called the triple point, represents the unique conditions under which all three phases exist in equilibrium together. Phase diagrams are specific for each substance and mixture.

g Ammonium nitrate was the oxidizing agent used that damaged the New York World Trade Center in 1993 and the Federal Building in

Cloud [144]

Answer: $51.3\times 10^3$ kJ

Explanation:

The thermochemical equation for decomposition of ammonium nitrate is:

$NH_4NO_3(s)\rightarrow N_2O(g)+2H_2O(g)$ $\Delta H=-82.1kJ$

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$

Given mass= 50.0 kg = $50.0\times 10^3g$ (1kg=1000g)

$\text{Number of moles of ammonium nitrate}=\frac{50.0\times 10^3g}{80g/mol}=0.625\times 10^3moles$

According to stoichiometry:

1 mole of $NH_4NO_3$ gives = 82.1 kJ of heat

Thus $0.625\times 10^3moles$ of $NH_4NO_3$ give = $\frac{82.1}{1}\times 0.625\times 10^3=51.3\times 10^3$ kJ of heat

Thus $51.3\times 10^3$ kJ of heat is evolved from the decomposition of 50.0 kg of ammonium nitrate.
