Explanation:

In the following reaction, in which direction, left or right, will the equilibrium shift if the following changes are made?

2NO (g) + H2 (g) ⇌ N2O (g) + H2O (g) + 36 kJ (heat)

N2 O (g) is added
Equilibrium shifts (LEFT / RIGHT)
H2 (g) is added
Equilibrium shifts (LEFT / RIGHT)

Answers

Answer:

Shifts to the left.

Shifts to the right.

Explanation:

Based on Le Châtelier's principle, when a change occurs in a system in equilibrium, the system will try to counteract the change that was made.

In the equilibrium:

2NO (g) + H₂ (g) ⇌ N₂O (g) + H₂O (g) + 36 kJ (heat)

If N₂O is added, the equilibrium shifts to the left trying to decrease the concentration of N₂O added.

If H₂ is added, the equilibrium shifts to the right trying to decrease the concentration of H₂ added

As a sample of I2(s) sublimes to I2(g), the entropy of the sample

Answers

Gas molecules have more freedom in motion—and gases can be thought of as more “disordered”—than molecules of a solid, which are rigidly held in place. When it comes to phases, the entropy increases as you go from a solid to liquid to gas (the gaseous state having the greatest entropy and the solid state having the least).

So, as a sample of solid iodine sublimes to form gaseous iodine, the entropy of the sample increases.

A sealed container is heated from 110K to 175K. The gas begins at a volume of 95L, what is the new volume of the gas upon heating?

Answers

151 L

V1 = 95 L
T1 = 110 K
T2 = 175 K

Solve the equation for V2 —> V2 = V1T2/T1

V2 = (95 L)(175 K) / (110 K) = 151 L

A gas has a volume of 10.0 L at 20 degree Celsius. At what temperature does the gas have a volume of 20.0 L ?

Answers

Answer:

286 K

Explanation:

From the question,

Applying Charles law,

V/T = V'/T'.................... Equation 1

Where V = Initial Volume of gas, T = Initial Temperature of gas in Kelvin, V' = Final Volume of gas, T' = Final Temperature of gas in Kelvin

Make T' the subject of the equation

T' = V'T/V.................. Equation 2

Given: V = 10.0 L, V' = 20.0 L, T = 20°C  = (20+273) = 293 K.

Substitute these values into equation 2

T' = (20×293)/10

T' = 586 K

Hence the temperature of the gas is 586 K

Answer: a. nitrogen

Explanation:

Nitrogen comprises of five valence electrons in its outermost shell which enables it to form triple, double and single bonds with other atoms. It can share three electrons with other nitrogen atom and form a covalent bond. Moreover, nitrogen can form multiple bonds with itself and with other elements due to its small size and high electronegativity. Nitrogen, carbon, fluorine, and oxygen are the elements with which nitrogen can form bonding.

How many grams of carbon dioxide are produced from the combustion of 250.G of ethane, C3H8 in the reaction C3H8 +5O2 - 3CO2 +4H2O

Answers

Answer:

750 g of CO₂

Explanation:

The balanced equation for the reaction is given below:

C₃H₈ + 5O₂ —> 3CO₂ + 4H₂O

Next, we shall determine the mass of C₃H₈ that reacted and the mass of CO₂ produced from the balanced equation. This can be obtained as follow:

Molar mass of C₃H₈ = (12×3) + (8×1)

= 36 + 8 = 44 g/mol

Mass of C₃H₈ from the balanced equation = 1 × 44 = 44 g

Molar mass of CO₂ = 12 + (16×2)

= 12 + 32 = 44 g/mol

Mass of CO₂ = 3 × 44 = 132 g

SUMMARY:

From the balanced equation above,

44 g of C₃H₈ reacted to produce 132 g of CO₂.

Finally, we shall determine the mass of CO₂ produced by the reaction of 250 g of C₃H₈. This can be obtained as follow:

From the balanced equation above,

44 g of C₃H₈ reacted to produce 132 g of CO₂.

Therefore, 250 g of C₃H₈ will react to produce = (250 × 132)/44 = 750 g of CO₂.

Thus, 750 g of CO₂ were obtained from the reaction.

The number of grams of carbon dioxide should be 750 grams.

Calculation of the no of grams:

Since

The balanced equation for the reaction is

C₃H₈ + 5O₂ —> 3CO₂ + 4H₂O

Now

Molar mass of C₃H₈ = (12×3) + (8×1)

= 36 + 8 = 44 g/mol

Hence, Mass of C₃H₈ from the balanced equation = 1 × 44 = 44 g

Now

Molar mass of CO₂ = 12 + (16×2)

= 12 + 32 = 44 g/mol

Hence, Mass of CO₂ = 3 × 44 = 132 g

Now the no of grams should be

= (250 × 132)/44

= 750 g of CO₂.

what happens when a species is moved from its natural environment?

Answers

When a species is moved from its natural habitat it will learn to adapt to the new environment

Answer:

What may happen is everything where they used to live may change. Like The food cycle or the ecosystem. Here's a example. We took wolves from their natural environment and there was a big impact on what they did. Elks is what they ate all the time and kept their population low enough to where the environment can thrive but when they took the wolves the elks started to eat the berries in which Grizzly Bears need to feast on for their hibernation and they ate shrubs and other plant like stuff to which stuff couldn't grow anymore. The Elk population when from 5000 to 30000 from when they took the wolves that day. Another thing is how beavers build dams to keep water from going to certain places which help humans out too, but all the time the Elks would drink water and leave waste inside the water to where fish and other species inside the water started dying out. So beavers couldn't build. So this is my example of what may happen if a species is moved from their natural ground cause they could also ruin a food chain somewhere else.
