Which of the following correctly lists the compounds in order of decreasing acidity?
Nimfa-mama [501]

Answer:

A) H2O > HCCH > NH3 > CH3CH3

Explanation:

H2O is known as a neural compound which a pH close to 7.0. This however makes it more acidic due to it having the lowest pH when compared to the others in the option.

The other options however have their acidic strength as follows: HCCH > NH3 > CH3CH3. This explains why the pattern of decreasing acidic strength is H2O > HCCH > NH3 > CH3CH3

A vehicle is traveling at a speed of 92.5 km/h. What is this value in feet per second? Note that, by definition, 1 in = 2.54 cm.
Harlamova29_29 [7]

Answer:

v=84.3\frac{ft}{s}

Explanation:

Hello,

In this case, given that 1 kilometer equals 1000 meters, 1 meter equals 3.281 feet and 1 hour equals 3600 seconds, the required velocity in feet per second turns out:

v=92.5\frac{km}{h}*\frac{1000m}{1km}  *\frac{3.281ft}{1m} *\frac{1h}{3600s}\\ \\v=84.3\frac{ft}{s}

Regards.

ammonia (NH3(g) Hf=-45.9 kJ/mol) reacts. with oxygen to produce nitrogen and water (H2O(g) Hf = -241.8 kJ/mol according to the e
kherson [118]

Answer:

ΔH°_rxn = -195.9 kJ·mol⁻¹

Explanation:

                              4NH₃(g) + 3O₂(g) ⟶ 2N₂(g) +6H₂O(g)

ΔH°_f/(kJ·mol⁻¹):    -45.9          0                 0        -241.8

The formula relating ΔH°_rxn and enthalpies of formation (ΔH°_f) is

ΔH°_rxn = ΣΔH°_f(products) – ΣΔH°_f(reactants)

ΣΔH°_f(products) = -6(241.8) = -1450.8 kJ

ΣΔH°_f(reactants) = -4(45.9) = -183.6 kJ

ΔH°_rxn =  (-1450.8 + 183.6) kJ = -1267.2 kJ

What is the energy of an electromagnetic wave with a electromagnetic wave with a frequency of 3 * 10 Hz ?
Olin [163]

Answer:

E=1.989*10^{-32}J

Explanation:

From the question we are told that:

Frequency f=3 * 10 Hz

Generally the equation for Energy of an electromagnetic wave is mathematically given by

 E=hf

Where

  h=Planck's constant

  h=6.62607015 * 10^{-34}

Therefore

 E=6.62607015 * 10^{-34}*3 * 10

 E=1.989*10^{-32}J
