Explanation: <u><em>
These threats are destroying forests, which as Earth's lungs are the very solution to climate change in the first place.</em></u></h2>
<h2><u><em>
All over the world, the Rainforest Alliance’s work is assisting communities and businesses as they keep forests healthy and recycling greenhouse gases. We’re helping farming communities adapt to the impacts of climate change, and we’re working with forestry operations as they adopt techniques that benefit ecosystems and pursue innovative carbon sequestration projects.</em></u></h2>
The amount of Mg(OH)2 present after the reaction is complete is 0.136 moles of Mg(OH)2.
The equation of the reaction is;
2HNO3(aq) + Mg(OH)2(aq) -------> Mg(NO3)2(aq) + 2H2O(l)
Number of moles of Mg(OH)2 = 8.00 g/58 g/mol = 0.138 moles
Number of moles of HNO3 = 0.205 M × 24.2 mL/1000 = 0.00496 moles
Given that;
2 moles of HNO3 reacts with 1 mole of Mg(OH)2
0.00496 moles of HNO3 reacts with 0.00496 moles × 1 mole /2 moles = 0.00248 moles of Mg(OH)2
Hence, Mg(OH)2 is the reactant in excess.
The amount of Mg(OH)2 remaining = Amount present - Amount reacted
Hence; 0.138 moles - 0.00248 moles = 0.136 moles of Mg(OH)2

Answer:
Sublimation is the transition of a substance directly from the solid to the gas state, without passing through the liquid state. ... The reverse process of sublimation is deposition or desublimation, in which a substance passes directly from a gas to a solid phase.
