Answer:

Yes

Explanation:

Essential oil can seep through clothing as it is a soluble solution. Although, oil and water don't really mix so if the clothing is wet it may not.

When burning 180g of glucose in the presence of 192g of oxygen, water and carbon dioxide are produced?

Aneli [31]

The burning of glucose in presence of oxygen is called as combustion

The balanced reaction is

C6H12O6 + 6O2 ---> 6CO2 + 6H2O

Thus for each mole of glucose we need six moles of oxygen molecules

molar mass of glucose is 180g / mole

The moles of glucose present = mass / molar mass = 180 / 180 = 1 mole

The moles of oxygen present = mass / molar mass = 192 / 32 = 6 moles

Thus the reaction will go to completion and one mole of glucose will react with six moles of O2 to give six moles of CO2 and six moles of H2O

Mass of CO2 produced = moles X molar mass = 6 x 44 = 264 g

Mass of H2O produced = moles X molar mass = 6 x 18 = 108 g

A student is asked to determine the molarity of a strong base by titrating it with 0.250 M solution of H2SO4. The students is in

Hoochie [10]

Answer: The concentration of hydroxide ions in the strong base solution is 0.625 M

Explanation:

To calculate the molarity of solution, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Moles of solute}\times 1000}{\text{Volume of solution (in mL)}}$ .......(1)

For sulfuric acid:

Molarity of solution = 0.250 M

Volume of solution = (30.00 - 5.00) mL = 25.00 mL

Putting values in equation 1, we get:

$0.250M=\frac{\text{Moles of sulfuric acid}\times 1000}{25.00}\\\\\text{Moles of sulfuric acid}=\frac{0.250\times 25.00}{1000}=0.00625moles$

1 mole of sulfuric acid produces 2 moles of hydrogen ions and 1 mole of sulfate ions

Moles of hydrogen ions = $(2\times 0.00625)=0.0125moles$

At pH = 7

Moles of hydrogen ions = Moles of hydroxide ions = 0.0125 moles

Now, calculating the hydroxide ions in the base solution by using equation 1, we get:

Moles of hydroxide ions = 0.0125 moles

Volume of base solution = 20.0 mL

Putting values in equation 1, we get:

$\text{Molarity of }OH^-\text{ ions}=\frac{0.0125mol\times 1000}{20.0}\\\\\text{Molarity of }OH^-\text{ ions}=0.625M$

Hence, the concentration of hydroxide ions in the strong base solution is 0.625 M

What was the first property used to organize the periodic table?

Thepotemich [5.8K]

Answer:

Explanation:

atomic mass

In 1869, Mendeleev published the first periodic table of the elements. In his periodic table, Mendeleev arranged elements in rows by increasing atomic mass. Within a row, elements with lower atomic masses were on the left. Mendeleev started a new row every time the chemical properties of the elements repeated.
