1 answer:

6 0

chemical that appears as a colorless liquid, is used in a wide range of cleaning and personal care products, including hair dyes and bleaches, toothpaste and mouthwashes, bathroom cleaners and laundry stain removers. Hydrogen peroxide can also be found in over-the-counter first aid antiseptics, and it is used as a bleaching agent in some food products. It has other consumer and industrial uses as well, including water treatment.

How might the geometry of the product change (oh in an endo or exo position?) if all the methyl groups of camphor were replaced

Greeley [361]

Replacement of methyl groups of camphor is a reduction mechanism. Camphor is a bridged bi-cyclic compound. If you observe the structure of camphor the methyl group is placed with one carbon bridge (7, 7) and two carbon bridge (1). Attack from face of one carbon bridge is termed as exo attack whereas from face of two carbon bridge is termed as endo attack. So replacement will lead to mix of both and formation of two stereo isomers.

Reduction mechanism is often shown with a U-shaped arrow pointing the attack by ion such as in nucleophilic addition reaction.

Difference between hard water and cold water ?

sweet-ann [11.9K]

The hardness of water is determined primarily by the amount of calcium and magnesium it contains. ... Instead of having higher levels of calcium and magnesium, soft water tends to have higher concentrations of sodium, or salt.

A quantity of 0.0250 mol of a gas initially at 0.050 L and 19.0°C undergoes a constant-temperature expansion against a constant

KiRa [710]

Answer:

$V_2=2.995L\\\\W=248.5J$

Explanation:

Hello,

In this case, for us to compute the final volume we apply the Boyle's law that analyzes the pressure-volume temperature as an inversely proportional relationship:

$P_1V_1=P_2V_2$

So we solve for $V_2$ by firstly computing the initial pressure:

$P_1=\frac{nRT}{V_1}=\frac{0.025mol*0.082\frac{atm*L}{mol*K}*(19+273.15)K}{0.050L} =11.98atm$

$V_2=\frac{P_1V_1}{P_2}=\frac{11.98atm*0.050L}{0.200atm}\\ \\V_2=2.995L$

Finally, we can compute the work by using the following formula:

$W=nRTln(\frac{V_2}{V_1} )=0.025mol*8.314\frac{J}{mol*K}*(19.0+273.15)K*ln(\frac{2.995L}{0.050L}) \\\\W=248.5J$

Best regards.

A 9.50 L balloon contains helium gas at a pressure of 680 mmHg. What is the final pressure in millimeters of mercury, of the hel

oee [108]

I've seen a question just like this but the 9.50L was 10 and the 23.0L was 20.0 and the answer was 328mmhg idk if they could be different or something.

4. How many moles are in 9.12 x 1023 molecules of sugar? And I want the steps to so that I can understand better

Aleksandr-060686 [28]

Answer:

Step 1: List the known quantities and plan the problem.

Known

number of C atoms = 4.72 × 10 24

1 mole = 6.02 × 10 23 atoms

Unknown

4.72 × 10 24 = ? mol C

One conversion factor will allow us to convert from the number of C atoms to moles of C atoms.

Step 2: Calculate.

4.72 times 10^{24} text{atoms C} times frac{1 text{mol C}}{6.02 times 10^{23} text{atoms C}}=7.84 text{mol C}

Step 3: Think about your result.

The given number of carbon atoms was greater than Avogadro’s number, so the number of moles of C atoms is greater than 1 mole. Since Avogadro’s number is a measured quantity with three significant figures, the result of the calculation is rounded to three significant figures.
