Compare uniformitarianism with catastrophism

wolverine [178]

Catastrophism is a theory that stated that earth was shaped by a suddentmassive violent events that happened within a short period of time.
Uniformitarianism, on the other hand, is a theory that stated earth was shaped by slow and gradual events over a long period of time, which could take millions of years.

Testbank, Question 095 What is the expected major organic product from the treatment of 4-methyl-2-pentyne with excess hydrogen

Sedbober [7]

Answer:

See explanation and image attached

Explanation:

The addition of excess hydrogen to alkyne in the presence of a platinum catalyst leads to complete hydrogenation of the alkyne as shown in the image attached.

Therefore, an alkane is obtained as the major organic product when excess hydrogen reacts with an alkyne in the presence of a platinum catalyst.

What is a maximum negative displacement of a wave

AnnZ [28]

The maximum negative displacement of a wave is the same as its amplitude.

As a wave travels through space, its particles are sometimes above the

x-axis (+) and sometimes below it (-).

The maximum displacement from the axis is the amplitude of the wave.

The amplitude of the wave is the same in both the positive and negative directions.

The combustion of 1.00 mol of glucose, C6H12O6, releases 2820 kJ of heat. If 2.0 g of glucose is burned in a calorimeter contain

DochEvi [55]

Answer:

The heat capacity of the calorimeter is 4.76 kJ/°C

Explanation:

Step 1: Data given

1.00 mol of glucose releases 2820 kJ of heat

Mass of glucose = 2.0 grams

Mass of water = 1000 grams

The temperature increases with 3.5 °C

Step 2: Calculate moles

moles glucose = mass glucose / molar mass glucose

moles glucose = 2.0 grams / 180.16 g/mol

moles glucose = 0.0111 moles

Step 3: Calculate heat produced by the combustion

Heat produced = 2820 kJ/mol * 0.0111 moles

Heat produced = 31.302 kJ = 31302 J

Step 4: Calculate heat absorbed by the water

Q = m*c*ΔT

⇒ with m = the mass of water = 1000 grams

⇒ with c = the specific heat of water = 4.184 J/g°C

⇒ with ΔT = The change in temperature = 3.5 °C

Q = 1000 * 4.184 *3.5

Q = 14644 J absorbed by the water

Step 5: Calculate heat basorbed by the calorimeter

Q = 31302 - 14644 = 16658 J absorbed by the calorimeter

Step 6: Calculate the heat capacity of the calorimeter

c= 16658 J / 3.5 °C

c = 4759 J/°C = 4.76 kJ/°C

The heat capacity of the calorimeter is 4.76 kJ/°C

The detector used in this experiment is called a Flame Ionization Detector (FID). As the different sample components come out of

Damm [24]

Answer:

c. 2-methyl-1-butanol.

Explanation:

As depicted in the question; the number of electrons produced is straightforwardly relative and directly proportional to the content and substance of carbon in the atom. So 2-methyl-1-butanol has the most highest and noteworthy carbon content (5carbons) among the accompanying species. So it will generate and create the biggest detector reaction response.
