Mole solute=Molar concentration(mol/L)*Volume solution(L)
250.0 mL=0.2500L
2.5M=2.5 mol/L
mole solute=2.5 mol/L*0.2500L= 0.625 ≈ 0.63 mol
Answer: AlCl3
Explanation:
Aluminum is in group 13 and has a valency of 3. Chlorine is in group 17 and has a valency of 1. When a compound is formed, it reflects the valencies of each of the combining elements. This can be simplified by saying that the combining elements exchange their valencies. Cl gets 3 and All gets 1 forming a compound with the formula shown above.
The number of significant figures within a number are the amount digits that are required to specify a number to a certain degree of accuracy. In the number, 0.0645 g, the 6 is the most significant figure and 4 is the second most significant figure. Therefore, rounding to two significant figures yields 0.064g.
Hello there!
The answer is 92000 tons per year
The palmetto landfill supplies methane (CH₄) for the BMW plant there. The gas is used to operate the turbines used to power the BMW campus. It reduces carbon dioxide emissions because the combustion of methane produces fewer CO₂ than the combustion of other gases like propane or butane, which are commonly used for powering turbines.
False, Atoms are the smallest units of matter that display both the chemical and physical properties of it, based on the structure of the atom.
