200.0 mL of a 0.845 M solution of KCl is diluted to 600.0 mL. What is the new concentration of the solution?
Ipatiy [6.2K]
  • M be molar concentration
  • V be volume

So

  • M1=0.845M
  • V1=200mL=0.2L
  • V2=0.6L
  • M2=?

\\ \tt\rightarrowtail M1V1=M2V2

\\ \tt\rightarrowtail 0.845(0.2)=0.6M2

\\ \tt\rightarrowtail 0.169=0.6M2

\\ \tt\rightarrowtail M2=0.281M

What will most likely happen in the absence of a vacuole?
Anon25 [30]

The cell will not store food, water, nutrients, and waste.

Explanation:

In the absence of a vacuole in a cell, the cell will not be able to store food, water, nutrients and its wastes.

The vacuole provides a storage medium for the products in the cell. It is a very important cell structure.

They store food and are both found in both plant and animal cells

*Genetic information are transmitted by the nucleus

* Energy is produced in the mitochondria

* Photosynthesis takes place using the chloroplast

Consider the molecule BF3. (a) What is the electron config- uration of an isolated B atom? (b) What is the electron con- figurat
anzhelika [568]

For the given molecule, we are asked to give-

  1. The electron configuration of an isolated B atom
  2. The electron configuration of an isolated F atom
  3. Hybrid orbitals should be constructed on the B atom to make the B–F bonds in Boron tri flouride
  4. valence orbitals, if any, remain unhybridized on the B atom.
  • The electron configuration of an isolated B atom:

as atomic number of B is 5

electronic configuration will be [He] 2s² 2p¹

  • The electron configuration of an isolated F atom:

as atomic number of F is 9

electronic configuration will be  [He] 2s² 2p5

  • Hybrid orbitals should be constructed on the B atom to make the B–F bonds in Boron tri flouride will be sp2.

as the one s and two of p orbital from the valance shell will hybridised to make 3 hybrid orbital of B resulting in 3 B-F bonds.

  • valence orbitals, if any, remain unhybridized on the B atom will be 1
