Ganezh [65]

Answer: option B. - A, B, D, E, C, H, F, G is correct using the principle of cross-cutting relationships.

The principle of cross-cutting relationships states that a fault or intrusion is younger than the rocks that it cuts through.

Explanation:

The full sequence of events is:

1. Layer A formed.

2. Layer B formed

3. Layer D formed.

4. Layer E formed

5. After layers A-B-D-E were present, intrusion C cut across all three.

6. Fault H formed, shifting rocks E through A and intrusion C.

7. Weathering and erosion created a layer of soil on top of layer F then G.

What mass, in grams, of CO2 and H20 N<br> is formed from 2.55 mol of propane?

Black_prince [1.1K]

Answer: The mass of $CO_2$ and $H_2O$ produced are 336.6 g and 183.6 g respectively.

Explanation:

The combustion reaction between propane and oxygen leads to formation of carbon dioxide and water.

Law of Conservation of mass states that the mass will remain constant for a balanced equation. This is carried out when the total number of atoms on reactant side is same as the total number of atoms on the product side. Thus the equation must be balanced.

$C_3H_8+5O_2\rightarrow 3CO_2+4H_2O$

a) 1 mol of propane produces = 3 moles of $CO_2$

Thus 2.55 mol of propane produces = $\frac{3}{1}\times 2.55=7.65 moles of [tex]CO_2$

mass of $CO_2=moles\times {\text {molar mass}}=7.65mol\times 44g/mol=336.6g$

b) 1 mol of propane produces = 4 moles of $H_2O$

Thus 2.55 mol of propane produces = $\frac{4}{1}\times 2.55=10.2 moles of [tex]H_2O$

mass of $H_2O=moles\times {\text {molar mass}}=10.2mol\times 18g/mol=183.6g$

The mass of $CO_2$ and $H_2O$ produced are 336.6 g and 183.6 g respectively.

(6) A mixture of 40.0 g of oxygen and 40.0 g of helium has a total pressure of 0.900 atm.

Elena L [17]

Answer:

Partial pressure of oxygen $= 0.100$ atm

Partial pressure of Helium $= 0.800$ atm

Explanation:

We will first find the number of moles of each gas

The molar mass of oxygen is $32$ grams per mole

The molar mass of helium is $4$ grams per mole

The number of moles of oxygen in the solution

$\frac{40}{32} \\1.25$

The number of moles of helium in the solution

The number of moles of oxygen in the solution

$\frac{40}{4}\\10$

Total number of moles in the solution is equal to

$10 + 1.25 \\11.25$

Partial pressure of oxygen

$\frac{1.25 }{11.25} * 0.900$ atm

$= 0.100$ atm

Partial pressure of Helium

$\frac{10 }{11.25} * 0.900$ atm

$= 0.800$ atm

Answer:

Heat and water.

Explanation:

Increased evaporation means more water vapor in the air and more energy ready to be liberated in the hurricane's thunderstorms as water vapor condenses.
