THESE ARE COMBUSTION REACTIONS SO, THE PRODUCT FOR BOTH OF THESE ARE CO2 AND H2O! Here is the balanced reaction equation:
1) C2H2 + 3O2 ➡️ 2CO2 + 2H2O
2) C2H12 + 5O2 ➡️ 2CO2 + 6H2O

Hey there!

Compounds with ionic bonds have higher melting points because of the forces needed to break through the strong forces of attraction holding it together.

Compounds with covalent bonds have lower melting points because less energy is needed to break the weaker forces of attraction.  

So, your answer is C. Compound 1 is ionic, and compound 2 is molecular.

Hope this helps!

Calculate the volume occupied by 0.845 mole of nitrogen gas, the pressure, and the temperature. Find the volume.
NeTakaya

Answer:

V = 15.9512 dm³

Explanation:

Given data:

Pressure = P = 1.37 atm

Temperature = T= 315 K

Number of moles of nitrogen= n = 0.845 mol

Volume = V = ?

Formula:

PV = nRT

Now we will put the values in equation.

V = nRT/ P

V = ( 0.845 mol× 0.0821 dm³.atm.K⁻¹.mol⁻¹ × 315 K) / 1.37 atm

V = 21.853 dm³. atm/  1.37 atm

V = 15.9512 dm³

How is the energy of a photon related to frequency?
Crank

Answer:

Energy and frequency are directly related to each other.

Explanation:

Energy of photon is directly related to each other. The wave with high frequency have high energy.

Mathematical expression:

E = h.f

f = frequency

h = plancks constant

while wavelength and energy are inversely related to each other. The wave with higher wavelength have low energy.

Mathematical relationship:

f = c/λ

F = h. c/λ

Example:

Frequency of wave = 1.0 ×10¹¹ Hz

Wavelength of wave = ?

Energy of wave = ?

Solution:

speed of wave = wavelength × frequency

wavelength = speed of wave/ frequency

wavelength = 3×10⁸ m/s / 1.0 ×10¹¹ s⁻¹

wavelength =  3×10⁻³ m

Energy:

E = h. f

E = 6.63×10⁻³⁴ Kg.m²/s × 1.0 ×10¹¹ s⁻¹

E = 6.63×10⁻²³ Kg.m²/s²

Kg.m²/s² = j

E = 6.63×10⁻²³ j
