Answer:
0.12 dm³ or 120 cm³
Explanation:
Hi there!
so first step find the number of moles
number of moles = mass ÷ Ar ( since o is an element and when it is alone, it is a diatomic molecule {O2} )
number of moles = mass ÷ Ar
number of moles = 0.16 ÷ ( 16 × 2 )
= 0.16 ÷ 32
= 5 × 10 ( power -3)
1 mol of O2 = 24 dm³ or 24 000 cm³
5 × 10 ( power -3) of O2 = (5 × 10 ( power -3)) × 24
= 0.12 dm³
or
= (5 × 10 ( power -3)) × 24 000
= 120 cm³
Answer:
Power plants that produce electricity emit at least two-thirds of all sulfur dioxide and more than one-third of all nitrogen oxides that pollute the air.
Hope this helps :)
An Arrhenius base<span> is a substance that, when dissolved in an aqueous solution, increases the concentration of hydroxide, or OH-, ions in the solution. I believe the correct answer from the choices listed above is option A. The reaction that </span>displays an example of an Arrhenius base would be <span>NaOH(s) --> Na+(aq) + OH–(aq). Hope this answers the question.</span>
It is equal to a gram, as there are 1,000,000 milligrams in a gram.
