Answer:B

Explanation:According to the law of superposition, sedimentary and volcanic rock layers are deposited on top of each other. They harden over time to become a solidified (competent) rock column, that may be intruded by igneous rocks and disrupted by tectonic events.

What is the correct order for the reactions that produce the following transformation. a. (1) H2/Lindlar (2) CH3CO2OH b. (1) H2/
Basile [38]

Answer:

Explanation:

Can you provide a picture? I can outline the reactions though. a) will make a Z double bond from a triple bond and then peroxyacid can do epoxidation. b) will make the Z double bond then ozonolysis to double bond will create to aldehyde compounds. c) is essentially useless unless there is a ketone or aldehyde in the compound already since H2/Pd will fully reduce the alkyne (which I am assuming is present) and so the peroxyacid can't do epoxidation and can only do baeyer villiger oxidation, and d) reduces the alkyne to an E alkene and then do epoxidation to give an epoxide (with trans steroechemistry)

At what temperature, in Celsius, will 88.0 g of Ne exert a pressure of 350. kPa in a
bezimeni [28]

Answer:

191 °C

Explanation:

We'll begin by calculating the number of mole in 88.0 g of Ne. This can be obtained as follow;

Mass of Ne = 88.0 g

Molar mass of Ne = 20 g/mol

Mole of Ne =?

Mole = mass /molar mass

Mole of Ne = 88 / 20

Mole of Ne = 4.4 moles

Next, we shall determine the temperature. This can be obtained as follow:

Mole of Ne = 4.4 moles

Pressure (P) = 350 KPa

Volume (V) = 48.5 L

Gas constant (R) = 8.314 KPa.L/Kmol

Temperature (T) =?

PV = nRT

350 × 48.5 = 4.4 × 8.314 × T

16975 = 36.5816 × T

Divide both side by 36.5816

T = 16975 / 36.5816

T = 464 K

Finally, we shall convert 464 K to celsius temperature. This can be obtained as follow:

T(°C) = T(K) – 273

T(K) = 464 K

T(°C) = 464 – 273

T(°C) = 191 °C

Thus, the temperature is 191 °C
