Ketones and aldehydes are simple compounds that contain a carbonyl group (a carbon-oxygen double bond). They are considered "simple" because they do not have reactive groups like −OH or −Cl attached directly to the carbon atom in the carbonyl group, as in carboxylic acids containing −COOH.

So your answer would be D.).

I hope that this helps. :)

The escape of gas through a small hole in a container

Doss [256]

The escape of gas through a small hole in a container is called effusion. This phenomenon happens when the diameter of the hole is small enough compared to the mean free path of the gas particles. This is governed by Graham's Law which states that the rate of effusion is inversely proportional to the molecular weight of the gas.

How many grams of Pb are contained in a mixture of 0.135 kg each of PbCl(OH) and Pb2Cl2CO3?

Dahasolnce [82]

Hey there!:

Given the mass of PbCl(OH) :

0.135 Kg = 0.135 Kg*(1000g / 1Kg) = 135 g

Molecular mass of PbCl(OH) = 207+35.5+16+1 = 259.5 g / mol

Atomic mass of Pb = 207 g/mol

Hence mass of Pb in 135 g PbCl(OH) :

(207 g Pb / 259.5 g PbClOH) * 135g PbClOH =

0.79768 * 135 => 107.68 g of Pb

For Pb2Cl2CO3 :

Given the mass of Pb2Cl2CO3 :

0.135 Kg = 0.135 Kgx(1000g / 1Kg) = 135 g

Molecular mass of Pb2Cl2CO3 = 2*207+2*35.5+12+3*16 = 545 g / mol

Mass of Pb present in 1 mol (=545 g / mol) of Pb2Cl2CO3 = 2*207 = 414 g

Hence mass of Pb in 135 g Pb2Cl2CO3:

(414 g Pb / 545 g PbClOH) * 135g PbClOH =

0.75963 * 135 => 102.55 g of Pb2Cl2CO3

Hope that helps!

Setting up a one-step unit conversion A student sets up the following equation to convert a measurement. (The ? stands for a num

Aneli [31]

Answer:

0.0008 m

Explanation:

We are given that 0.080 cm

We have to convert 0.080 cm into meter

To find the value of 0.080 cm in meter we are using unitary method

We know that

100 cm =1 m

1 cm = $\frac{1}{100} m$

Therefore, 0.080 cm = $\frac{1}{100}\times 0.080 m$

0.080 cm = $\frac{1}{100}\times \frac{80}{1000}m$

0.080 cm = $\frac{8}{10000}m$

0.08cm=0.0008 m

Hence, the value of 0.080 cm is equal to 0.0008 meter .
