Answer:
True
Explanation:
Because it would be false That Caves and caverns are common in dry regions where these is a layer of limestone near the surface.
Mass of iodine solid produced = 1.6 g
Iodine solid has a molecular formula : I2
Atomic mass of iodine = 126.904 g/mol
Therefore, molar mass of I2 solid = 2* 126.904 = 253.808 g/mol
Number of moles of a given substance is the ratio of its mass to the molar mass
# moles of I2 solid = mass of I2 solid/molar mass = 1.6 g/253.808 = 0.00630 moles
Hence, the # moles of iodine solid produced is 0.00630 moles
Answer:
D.
Explanation:
That would be the last option.
Repeated similar experimental outcomes are confirmation of the theory.
Answer:
i believe it is D because the composition does not change
