Three samples, each of a different substance, are weighed and their volume is measured. The results are tabulated. List the subs tances in order of decreasing density. Mass volume substance i 12.0 g 10.0 ml substance ii 10.0 kg 10.0 l substance iii 10.0 mg 12.0 μl
1 answer:
<h3>Answer;</h3>
Substance i > Substance ii > Substance iii
<h3>Explanation:</h3><h3><em><u>Substance i</u></em><em> :</em></h3>
Data Given;
Density = ?
Mass = 12 g
Volume = 10 mL
Formula Used;
Density = Mass ÷ Volume
Putting Values,
Density = 12 g ÷ 10 mL
Density = 1.2 g.mL ⁻¹
<h3><em><u>Substance ii</u></em><em> :</em></h3>
Data Given;
Density = ?
Mass = 10 Kg = 10000 g
Volume = 10 L = 10000 mL
Formula Used;
Density = Mass ÷ Volume
Putting Values,
Density = 10000 g ÷ 10000 mL
Density = 1 g.mL ⁻¹
<h3><em><u>Substance iii</u></em><em> :</em></h3>
Data Given;
Density = ?
Mass = 10 mg = 0.01 g
Volume = 12.0 μl = 0.012 mL
Formula Used;
Density = Mass ÷ Volume
Putting Values,
Density = 0.01 g ÷ 0.012 mL
Density = 0.833 g.mL ⁻¹

Answer:For a typical experiment, you should plan to repeat it at least three times (more is better).
Explanation:
Answer:
Explanation:
From the given information:
A → B k₁
B → A k₂
B + C → D k₃
The rate law =
Using steady-state approximation;
From equation (1), we have:
when the pressure is high;
k₂ << k₃[C]
k₂ >> k₃[C]
The answer is Latitude (B)

-2? if wrong im sorry please tell me what I did that was incorrect ty Explanation:
Answer:
The reactant/reagent that would be most atom economical is EtI (Ethy Iodide) and KOH (potassium oxide) as base
This is because the iodo group are weak base hence they have a good leaving character (i.e they are unstable on their own ) which would increase the rate of reaction and the strong base KOH give the most atom economical
