Answer:
1.04 moles of AlCl₃
Explanation:
Balanced Equation: 2Al°(s) + 3Cl₂(g) => 2AlCl₃(s)
Approach => convert given data (28 g Al°) to moles. The number of moles AlCl₃ would equal the number of moles aluminum because coefficients for Aluminum and Aluminum Chloride are equal.
moles Al° = (28g)/(27g/mole ) = 1.04 mole Al°
From balanced equation moles AlCl₃ produced equals moles of Al° produced = 1.04 mole AlCl₃ because coefficients of Al° & AlCl₃.
Some rocks contain carbonate minerals, and the acid test can be used to help identify them.
Answer: The new volume is 95.45 mL.
Explanation:
Given:
= 45.0 mL,
= 0.98 atm
= 2.1 atm,
= ?
According to Boyle's law, at constant temperature the pressure of a gas is inversely proportional to its volume.
Therefore, formula used to calculate the new volume is as follows.

Substitute the values into above formula as follows.

Thus, we can conclude that the new volume is 95.45 mL.
