In 2-3 sentences, explain WHY the Elodea cells placed in the salt solution look different than they do in water. Include in your

ZanzabumX [31]

Answer:

The phenomenon of plasmolysis.

Explanation:

When cells of Elodea are placed in a salt solution the phenomenon of plasmolysis occurs and the water will start to move out from the cell. The concentration of salts in the cell will get high due to the diffusion of salt molecules inward. The organelles will look like as they are centered to the cell by hook.

Determine the oxidation state of nitrogen in lino3.

Andre45 [30]

Answer : The oxidation state of nitrogen in $LiNO_3$ is, (+5)

Explanation :

Rules for the oxidation numbers :

The oxidation number of a free element is always be zero.
The oxidation number of a monatomic ion equal to the charge of the ion.
The oxidation number of Hydrogen (H) is +1.
The oxidation number of oxygen (O) in compounds is usually -2, but it is -1 in the peroxides.
The oxidation number of a Group 1 element in a compound is +1.
The oxidation number of a Group 2 element in a compound is +2.
The oxidation number of a Group 17 element in a binary compound is -1.
The sum of the oxidation numbers of all of the atoms in a neutral compound is zero.
The sum of the oxidation numbers in a polyatomic ion is equal to the charge of the ion.

The given compound is, $LiNO_3$

Let the oxidation state of 'N' be, 'x'

$(+1)+x+3(-2)=0\\\\x=+5$

Hence, the oxidation state of N is, (+5)
