What is a mole?</h3>
A mole is defined as 6.02214076 × of some chemical unit, be it atoms, molecules, ions, or others.
Calculating moles of
Number of mole of =
= = 0.12 mol
As is clear from the reaction stoichiometry, 9 moles of 6 moles of .
Calculating the number of moles of
= 0.18 mol
Mass of =5.76 g
Hence, 5.76 g of are consumed when yield 5.3 grams of .

The order of decreasing energy is ultraviolet rays, infrared rays, and microwaves.
Frequency is defined as the number of occurrences of the event. In wave function, frequency is the number of times the given waveform passes through a given point. The SI unit of frequency is Hertz.
Photons are particles that do not contain mass but possess energy. Photon energy is calculated by the formula Planck's constant h ( 6.63✖10-34 J/s) multiplied by the frequency. Hence frequency is directly proportional to the energy of the photon.
Higher frequency waves will have higher energy. Lower frequency waves will have lower energy.

Rank the following photons in terms of decreasing energy:
(a) IR (v = 6.5 x 10¹³ s⁻¹)
(b) microwave (v = 9.8 x 10¹¹ s⁻¹)
(c) UV (v = 8.0 x 10¹⁵ s⁻¹)
<span>Cu + 2 AgNO</span>₃<span> = 2 Ag + Cu(NO</span>₃<span>)</span>₂
mole ratio:
1 mole Cu --------------> 2 moles Ag
? mole Cu --------------> 3.50 moles Ag
moles Cu = 3.50 x 1 / 2
moles Cu = 3.50 / 2
= 1.75 moles
Answer B
hope this helps!
B
Explanation:
cause carbon is less than all of them in periodic table which therefore least in the group
I think C. Mutualism.
