The presence of unconformities can be used to determine the relative age of two rocks. Therefore, the correct answer is B

Unconformity refers to a non-depositional surface which separates two strata of different age. Unconformity shows that deposited sedimentary rock was not continuous. Unconformity indicates that the older layer was exposed to erosion before the younger layer.

<h2>Further Explanation</h2>

The upper rocks, that is, the rocks that are higher than the unconformities are younger than those beneath the conformity.

In general, an unconformity indicates the period when no sediments were preserved.

The types of unconformities include

Disconformities: this is a type of unconformity between parallel layers of sedimentary rocks. It represents the time of erosion and they are characterized by some qualities of subarea emotion.
Nonconformity: this is between an ingenious rock and sedimentary rock when the sedimentary rock was placed on eroded igneous rock
Angular unconformity: this is a type of unconformity in which a parallel layer of sedimentary rocks are deposited on eroded layers and generate discordance with the horizontal layers.

Other types of unconformity include:

Paraconformity
Buttress unconformity
Blended unconformity

Therefore, the presence of unconformities can be used to determine the relative age of two rocks.

Pani-rosa [81]

Answer:

b. Extraction with a solution of sodium hydrogen carbonate, separating the layers, followed by drying and evaporating the organic layer.

Step-by-step explanation:

The ether solution contains your product, benzaldehyde, and some starting material, benzoic acid, the purification steps are:

Extract with a solution of NaHCO₃. The ether layer contains benzaldehyde, and the aqueous layer contains sodium benzoate.
Separate the layers. Keep the ether layer.
Dry the ether solution.
Distill the ether (boiling point 35 °C) and purify the benzaldehyde (178 °C) by steam distillation.

a. is wrong. Extraction with HCl will not remove much of the benzoic acid.

c. is wrong. If you evaporate the organic layer, you will have a mixture of benzaldehyde and benzoic acid.

d. is wrong. If you work with the aqueous layer, you will end up with benzoic acid,

Red mercury (II) oxide decomposes to form mercury metal and oxygen gas according to the following equation: 2HgO (s) 2Hg (l) + O

diamong [38]

hey there!:

2HgO (s) => 2Hg (l) + O2 (g)

2 moles of HgO decompose to form 2 moles of Hg and 1 mole of O2 according to the reaction mentioned in the question.

So 4.00 moles of HgO must give 4 moles of Hg and 2 moles of O2 theoretically.

603 g of Hg = 603 / 200.6 = 3 moles

Percent yield = ( actual yield / theoretical yield) * 100

= ( 3/4) * 100

= 75 %

Hope this helps!

A student increases the temperature of a 417cm³ balloon from 278k to 231k. Assuming constant pressure, what should the new volum

viva [34]

Charles law states that volume of gas is directly proportional to temperature at constant pressure
V/T = k
where V - volume , T - temperature and k - constant
$\frac{V1}{T1} = \frac{V2}{T2}$
where parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation

in the question it states that the temperature has been increased from 278 K to 231 K but it should actually be temperature is decreased from 278 K to 308 K
substituting the values in the equation
$\frac{417cm^{3} }{278K} = \frac{V}{308 K}$
V = 462 cm³
the answer should be D. 462 cm³
