When Raymond observes certain natural phenomena, he often forms ideas about their causes and effects. Suppose that Raymond surmi

ses that leaves change color in autumn due to scarcity of sunlight. In order to test whether his idea is accurate, he must first construct a falsifiable that defines a clear relationship between two variables. Raymond’s next step is to that would isolate and test the relationship between the two variables. This task can be pretty daunting because Raymond will need to identify and eliminate any variables that could confuse test results.

Answer:

The two variables involved here are sunlight and color of the leaves.

A statement is falsifiable if some observation might show it to be false. In this case, the falsifiable is:  leaves change color in autumn due to scarcity of sunlight. If anybody observes leaves with no change in color after a scarcity of sunlight, then the hypothesis is false.

The active ingredient in aspirin is acetylsalicylic acid. A 2.51-g sample of acetylsalicylic acid required 27.36 mL of 0.5106 M
polet [3.4K]

Hey there!

mass of sample = 2.51 g of Aspirin

Number of moles of base  ( NaOH ) :

M*V = 27.36*0.5106 = 13.9700 mmol of base

M*V = 13.68*0.516 = 7.05888 mmol of acid

pKa calculation:

pH = pKa + log(A-/HA)

3.48 = pKa + log(7.05888 / (13.9700 -7.05888))

Pka =3.49 -  log(7.05888 / (13.9700 -7.05888))

pKa = 3.48

Molar mass calculation:

molar mass = mass/mol

(2.51)/(13.9700 *10⁻³) =

molar mass 180 g/mol approx


Hope that helps!

What is the volume in liters of 321 g of liquid with a density of 0.84 g/mL
Rasek [7]
Density is weight by volume.   

First.  If you divide the weight by density you can find the volume

Second you must convert the ML in to Liters.

\frac{321 \frac{g}{1}}{0.84 \frac{g}{mL}} = \frac{321(g)(mL)}{0.84g}=\frac{321mL}{0.84}=382.14mL

1L=1000ml

\frac{1L}{1000mL}

(382.14mL)( \frac{1L}{1000mL})= \frac{(382.14mL)(L)}{1000mL} =\frac{382.14L}{1000}=0.38214L

0.38214 Liters.

How many moles of hydrogen are in 3.0 moles of C6H12O6?
Anastaziya [24]

Answer:

36 mol H

Explanation:

1 molecule C₆H₁₂O₆ contains 12 H atoms

1 mol C₆H₁₂O₆ contains 12 mol H atoms;      Multiply by 3

3 mol C₆H₁₂O₆ contains 36 mol H atoms

If you are talking about moles of hydrogen molecules (H₂), you divide 36 by 2 and get 18 mol H₂.
