Answer:
6.94 × 10^33Hz
Explanation:
E = hf
Where;
E = Energy of wave (J)
h = Planck's constant (6.626 × 10^-34J/s)
f = frequency (Hz)
According to the information provided in this question, the hypothetical energy of the wave is 4.6J
Hence, using E = hf
4.6 = 6.626 × 10^-34 × f
f = 4.6 / 6.626 × 10^-34
f = 0.694 × 10^34
f = 6.94 × 10^33Hz
At STP, the volume of a gas represents the number of particles.That said, from the chemical reaction one mole of oxygen reacts with two moles of co to produce the product, CO2At STP, 3 moles of Oxygen will produce 6 moles of CO2. Hence It follows that at standard temperature and pressure, 6.0 L of CO2 will be produced. Option D.
Answer:
Well,
Conducting rods are good for detecting oscillating electric fields and conducting loops are good for detecting the presence of radio waves.
1.05moles
Explanation:
Given parameters:
Number of molecules of C₂H₆ = 6.29 x 10²³molecules
Unknown:
Number of moles = ?
Solution:
The mole is the amount of substances that contains Avogadro's number of particles i.e 6.02 x 10²³
To find the number of moles:
number of moles = 
number of moles = 
number of moles = 1.05moles
