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.
When an electron moves from a higher to a lower energy level, energy is released (often as light).
Explanation:
in this question, we're asked how to determine whether we have a metallic or nonmetallic substance.So what you want to do is one to remember that metals are malleable and Nonmetal are brittle. So if we were to hammer the metal, it would be very malleable, but the nonmetal would fall apart. And never we could just hammer the sample and see whether it was malleable. And therefore it would be a medal or a brittle and therefore being nonmetal.
Oxidation number is defined as the total number of electrons that are gained or lost by the atom to form a chemical bond.
the oxidation number of the compound H₂S is 0.
the sum of the oxidation numbers of the individual elements should add up to the oxidation number of the compound.
(oxidation number of H x 2 H ions) + oxidation number of S = 0
since we know the oxidation number of H, lets name the oxidation number of S = x
(+1 * 2 )+ (x) = 0
2 + x = 0
x = -2
oxidation number of S is -2
The pressure of the nitrogen gas produced is determined as 44.77 atm.
<h3>
What is the pressure of the Nitrogen gas?</h3>
The pressure of the nitrogen gas is determined from ideal gas equation, as shown below;
PV = nRT
P = nRT/V
where;
- n is number of moles = 2 moles
- R is ideal gas constant = 0.08205 L.atm/mol.K
- T is temperature = 68⁰C = 68 + 273 = 341 K
- V is volume = 1.25 L
P = (2 x 0.08205 x 341)/(1.25)
P = 44.77 atm.
