How do the products of chemical reactions compare to their reactants?

The products of chemical reactions often have completely different properties than the reactants, like viscosity, boiling and melting temperatures, etc.

That is because the atoms form new and different bonds to give the products.

Which will cause the value of the equilibrium constant to change? (2 points)

Sonbull [250]

answer

changing the temperature and increase in the pressure

Change in concentration, pressure, catalyst, inert gas addition, etc. have no effect on concentration, pressure, catalyst, inert gas addition lead to a shift in equilibrium position .

You have a gas at a volume of 9.71 L at a pressure of 209 torr and at 10.1 °C. What

Usimov [2.4K]

Answer:

219.95 °C

Explanation:

Given data:

Volume of gas = 9.71 L

Initial pressure = 209 torr (209/760 = 0.275 atm)

Initial temperature = 10.1 °C (10.1 +273 = 283.1 K)

Final temperature = ?

Final pressure = 364 torr (364/760 =0.479 atm)

Solution:

According to Gay-Lussac Law,

The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.

Mathematical relationship:

P₁/T₁ = P₂/T₂

Now we will put the values in formula:

0.275 atm / 283.1 K = 0.479 atm/T₂

T₂ = 0.479 atm × 283.1 K/ 0.275 atm

T₂ = 135.6 atm. K /0.275 atm

T₂ = 493.1 K

Kelvin to °C:

493.1 K - 273.15 = 219.95 °C

What causes a substance to be hydrophobic?

WITCHER [35]

The hydrophobic effect is caused by nonpolar molecules clumping together. Large macromolecules can have hydrophobic sections, which will fold the molecule so they can be close to each other, away from water. Many amino acids in proteins are hydrophobic, helping the proteins obtain their complicated shapes. The hydrophobic effect extends to organisms, as many hydrophobic molecules on the surface of an organisms help them regulate the amount of water and nutrients in their systems.

Fill in the blanks using terms from this unit.

kolbaska11 [484]

Answer:

See the answer below

Explanation:

Even though plants are rooted in the ground, they still move, exert force, and do work.

Plant cells have very strong cell walls that allow pressure to build up inside of the cell as water is absorbed. This pressure is called turgor.

When turgor pressure is high enough in a cell, the cell walls become firm and as a result, the cell becomes rigid and the plant is able to stand tall and straight.

When a plant does not get enough water, the turgor pressure inside of the cells decreases. A decrease in pressure pushing against the cell wall causes the cells to lose their shape and shrink. This causes the plant to begin to droop or wilt.

When the wilted plant gets enough water, the cells will become rigid again, and the plant will stand firm and straight once again.
