Answer:
Five peaks
Explanation:
GaAs would show two peaks:
Ga-69 + As-75 = 144
Ga-71 + As-75 = 146
Their intensities are in the ratio 60 : 40 = 100:67.
Ga₂S₂ would show three peaks:
Ga-69 + Ga-69 + 2As-75 = (Ga-69)₂(As-75)₂ = 288
Ga-69 + Ga-71 + 2As-75 = (Ga-69)(Ga-71(As-75)₂ = 290
Ga-71 + Ga-71 + 2As-75 = (Ga-71)₂(As-75)₂ = 292
Their relative intensities are in the ratio
(60 + 40)² = 60² : 2×60×40 : 40² = 3600 : 4800 : 1600 = 75 : 100 : 33
A spectrum of a mixture of GaAs and Ga₂As₂ would show five peaks:
Two at m/e 144 and 146 with intensity ratios 100: 67 and
Three at m/e 288, 290, and 292 with intensity ratios 75:100 :33.
We cannot predict the absolute sizes of the peaks because we do not know the relative amounts of GaAs and GaAs₂.
- In the reduction process of photosynthesis, electrons are transported from water to carbon dioxide.
- According to photon theory here the photons behave as light energy particle.
- By capturing sun energy (photons), chlorophyll aids in this process.An electron in the chlorophyll molecule gets excited from a lower to a higher energy state when chlorophyll receives energy from sunlight.
- Excessive sunshine is the main cause of leaves turning a darker green color. Lack of sunlight causes a plant's leaves to create more chlorophyll, which is what gives the plant its green hue.
- The color of the leaf is darker green than typical because of the increase in chlorophyll concentration per unit area.
<h3>What is photon theory?</h3>
The photon theory of light states that photons have simultaneous particle and wave behavior. pass through empty space at a constant speed, or "the speed of light". possess rest energy and zero mass.

the answer is b it is composed of protons and neutrons.

Sodium has a noble gas configuration, plus a single high energy 3s1 electron. This electron is more stable when associated with more electronegative atoms and polyatomic ions. Therefore, sodium loses a single electron (losing a negative charge, granting the sodium atom a +1 charge). Positive and negative charges attract each other in order to balance out the charge (reach a low energy state), so two +1 sodium atoms need to associate with either two separate -1 charges, or a single -2 charge. The only polyatomic listed here that satisfies the -2 (formally written 2-) needed to attract both sodium atoms is the Carbonate ion, CO3(2-).
