Corals will continue to expel algae from their cells if global warming continues, in order to avoid poisonous buildup. Corals will perish as a result of this. The algae are not protected and cannot perform photosynthesis without the presence of corals. The algae will also perish as a result of this.
Atomic mass = 39
number of neutrons = 20
Number of protons= 19
Electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1
The number of electron in first shell = 2
number of electrons in n=3 shell = 8
A. an ion
The atom gains a net electrical charge if the number of protons and electrons are not equal which makes it an ion.
Answer:
The answer is below
Explanation:
Avogadro stated that "Equal volumes of all gases at the same temperature and pressure contain the same number of molecules". Hence at standard temperature and pressure 1 mole of a gas occupies 22.4 liters of volume.
1 mol = 22.4 liters
Given a gas with 1 L and mass of 1.92 g at STP.
number of moles = 1 L / (22.4 L / mol) = 0.0446 mol
The molar mass = mass of gas / number of moles
molar mass = 1.92 g / 0.0446 mol
molar mass = 43.008 g / mol
