Osmosis is the process responsible for carrying nutrients and water from groundwater supplies to the upper parts of trees. The o

smotic pressures required for this process can be as high as 20.1 atm. What would the molar concentration of the tree sap have to be to achieve this pressure on a day when the temperature is 24 C?

Answer:

0.825 M

Explanation:

The osmotic pressure is a colligative property, that can be calculated using the following expression.

π = M × R × T

where,

π is the osmotic pressure

M is the molarity

R is the ideal gas constant

T is the absolute temperature (24°C + 273 = 297 K)

M = π / R × T = 20.1 atm / (0.08206 atm.L/mol.K) × 297 K = 0.825 M

11Alexandr11 [23.1K]

Answer:

2HClO4(aq) + Ca(OH)2(aq) → Ca(ClO4)2(aq) + 2H2O(l)

Perchloric acid + Calcium hydroxide → Calcium perchlorate + Water.

Explanation:

This is a neutralization reaction where the acid, Perchloric acid reacts completely with an appropriate amount of base, aqueous Calcium hydroxide to produce salt, aqueous Calcium perchlorate and water, liquid H2O only.

During this reaction, the hydrogen ion, H+, from the HClO4 is neutralized by the hydroxide ion, OH-, from the Ca(OH)2 to form the water molecule, H2O.

Thus, it is called a neutralization reaction.

Bond order of n2<br><br>bond order of N2 ​
snow_lady [41]

Answer:

The MO method for N2+ gives the bond order equal to 2.5. But first, we look at the diagram of molecular orbitals for N2 (the bond order for the nitrogen molecule is 3). the N2+ molecule). That is, the bond order for N2+ is 2.5.

Which option defines kinetic energy?(1 point)
MAVERICK [17]

The option which accurately defines kinetic energy from the choices above is:

the energy an object has because of its motion

The correct answer choice is option c

In order words, kinetic energy is that type of energy which a body or an object posess due to its relative motion.

<h3>What is energy?</h3>

Energy can simply be defined as the capacity of doing work.

Energy is a derived quantity; meaning that it is obtained from the combination of fundamental quantities.

The unit of energy joules.

Other examples of derived quantities just like energy too are:

  • Volume
  • Speed
  • Acceleration
  • Density.
  • Upthrust
  • Momentum
  • Momentum
  • Power
  • Pressure
  • Force

Below are some few forms of energy; these are:

  • Kinetic energy
  • Potential energy
  • Mechanical energy
  • Solar energy
  • Light energy
  • Chemical energy

So therefore, the option which accurately defines kinetic energy from the choices above is:

the energy an object has because of its motion
