Answer
Explanation:
Evidence from fossils, glaciers, and complementary coastlines helps reveal how the plates once fit together. Fossils tell us when and where plants and animals once existed. ... This distribution of fossils led to theories that the southern continents were once joined in a supercontinent called Gondwana.
The mass of silver chloride produced is 24.79g.
Given,
volume = 1.11 L
Molarity = 0.156 M
First, convert molarity to moles by multiplying by the volume:
0.156 M AgNO3 = (0.156 moles AgNO3)/1 L x 1.11 L = 0.173 moles AgNO3
We are only interested in AgCl, not AgNO3. We convert moles of silver nitrate to moles of silver chloride using the balanced equation. This is a 1:1 conversion:
0.173 moles AgNO3 x (1 mole AgCl)/(1 mole AgNO3) = 0.173 moles AgCl
To get mass from moles, we multiply by the molar mass:
0.173 moles AgCl x (143.32 g/mol) = 24.79 g AgCl
