The limiting reactant is Cl₂ (chlorine).
Explanation:
We have the following chemical reaction:
2 Al (s) + 3 Cl₂ (g) → 2 AlCl₃ (s)
And we start with 2.7 g of Al and 3.12 g of Cl₂.
First we calculate the number of moles of each reactant.
number of moles = mass / molar weight
number of moles of Al = 2.7 / 27 = 0.1 moles
number of moles of Cl₂ = 3.12 / 71 = 0.044 moles
From the chemical reaction we see that 2 moles of Al are reacting with 3 moles of Cl₂ so 0.1 moles of Al are reacting with 0.15 moles of Cl₂ which is a quantity higher than our available one of 0.044 moles of Cl₂. The limiting reactant is Cl₂.

Answer:
Most igneous, metamorphic, and sedimentary rocks contain rubidium (Rb) and strontium (Sr) in detectable amounts. However, the concentrations of these elements are almost always less than 1 percent, and they are therefore rarely determined in routine chemical analyses. Neither rubidium nor strontium is a major constituent in the common rock-forming silicate minerals, although strontium does form a carbonate (strontianite) and a sulfate (celestite) which are found in some hydrothermal deposits and certain sedimentary rocks, particularly carbonates.

Explanation:
Hello! The factors mentioned previously are essential substances for the life and health of our bodies. Not only in humans, but also for animals. They are factors that are linked and contribute to physical and mental energy, growth and life. Are essentials because humans can't live without that.
