Answer:

The entropy of a substance can be obtained by measuring the heat required to raise the temperature a given amount, using a reversible process . The standard molar entropy, So, is the entropy of 1 mole of a substance in its standard state, at 1 atm of pressure. (Below are listed tips)

- At absolute zero (0 K), the entropy of a pure, perfect crystal is zero.

- The entropy of a substance can be obtained by measuring the heat required to raise the temperature a given amount, using a reversible process.

- The standard molar entropy, So, is the entropy of 1 mole of a substance in its standard state, at 1 atm of pressure.

Why methyl orange in basic medium is yellow and why it is red in acidic medium?

Sholpan [36]

Methyl orange shows red color in acidic medium and yellow color in basic medium. Because it changes color at the pKa of a mid strength acid, it is usually used in titration for acids. Unlike a universal indicator, methyl orange does not have a full spectrum of color change, but it has a sharp end point.

Ichthyothereol is isolated from the leaves of Ichthyothere terminalis. It is so toxic to fish that they will jump out of the wat

Snezhnost [94]

Answer:

See the explanation

Explanation:

We have to start by analyzing the molecule. In the molecule, we have <u>two types of isomerism</u>. In the double bond, we can have <u>E or Z isomerism</u>, and additionally, we have a <u>chiral carbon</u> (a carbon with 4 different bonds) (See figure 1). With this in mind, we can have <u>4 possible isomers</u>.(See figure 2).

<u>a) (3S)-2-(E)-ichthyothereol</u>

<u>b) (3R)-2-(E)-ichthyothereol</u>

<u>c) (3R)-2-(E)-ichthyothereol</u>

<u>d) (3R)-2-(Z)-ichthyothereol</u>

A galvanic (voltaic) cell consists of an electrode composed of nickel in a 1.0 M 1.0 M nickel(II) ion solution and another elect

Katarina [22]

Answer:

<h3>So the standard electrode potential of the cell is 1.05 V</h3>

Explanation:

electrode composed of nickel in a 1.0 M

1.0 M nickel(II) ion solution and another electrode composed of silver in a 1.0 M 1.0 M silver ion solution,

connected by a salt bridge. Calculate the standard potential for this cell at 25 °C .

2Ag+ + Ni -----> 2 Ag + Ni +2

Eocell = Eo cathode - Eo anode

= Eo Ag+/Ag - Eo Ni+2/Ni

=0.80 - (-0.25)

=0.80 + 0.25

= 1.05

<h3>So the standard electrode potential of the cell is 1.05 V</h3>

Y=x+4 how to solve I need the know plaese

sweet [91]

you can't solve that, you need more information in that equations like and x or an y.

Otherwise, the equation stays like that.
