<u>Answer:</u> The electrons are transferred during a redox reaction.

<u>Explanation:</u>

Redox reaction is defined as the reaction in which oxidation and reduction reaction occur simultaneously.

Oxidation reaction is defined as the reaction in which an atom looses its electrons. The oxidation number of the atom gets increased during this reaction.

$X\rightarrow X^{n+}+ne^-$

Reduction reaction is defined as the reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.

$X^{n+}+ne^-\rightarrow X$

Electrons are transferred from one atom to another in this type of reaction.

Answer

1.5x10^-3 m

24.91x10^5

Explanation:

15 millimeters

- 1 mm = .0015

exponent indicates which way the decimal moved and to how many places

we moved the decimal backwards (negative) 3 spaces

2491 km= 2491000 m

exponent indicates which way the decimal moved and to how many places

we moved the decimal forwards (positive) 5 spaces

2491000.00 --> 24.91000

If you only have 36.5 grams of Potassium Carbonate (K2CO3 molar mass = 138.2 g/mole). How many liters of a 0.52 M solution can y

kirza4 [7]

Answer:

0.508 L of solution.

Explanation:

Always a safe bet to convert to moles:

$n= {m \over MM}\\$

Where n is moles, m is mass, and MM is molar mass.

Now remember the equation for concentration (molarity):

$C={n \over V}$

Where C is the concentration, n is moles, and V is volume.

To make this easy, combine the two equations (note n appears in both, so you can do a substitution) and solve for V as the question asks:

$C={m \over MM \times V}\\0.52={36.5 \over 138.2 \times V}\\V={36.5 \over 138.2 \times 0.52}\\V=0.508$

Therefore we can make 0.508 L of solution.

Explain the optical activity of malic acid? <br>Draw a pair of stereoisomers of malic acid.

mr_godi [17]

Under standard temperature and pressure, the optical activity of malic acid changes in the following ways:

Wavelength of light
Magnitude
Temperature
Concentration of solvent.

<h3>What is an optical activity?</h3>

An optical activity is also referred to as optical rotation and it can be defined as the ability of a substance or chemical compound to rotate the plane of polarization of a beam of plane-polarized light that passes through it.

<h3>What is malic acid?</h3>

Malic acid refers to an organic compound (dicarboxylic acid) that is typically made by all living organisms and its molecular formula is $C_4H_6O_5$ . Malic acid is considered to be one of the most satisfactory substances to be used when studying optical activity because of its chemical properties such as having single asymmetric carbon atoms.

Under standard temperature and pressure, the optical activity of malic acid changes in the following ways:

Wavelength of light
Magnitude
Temperature
Concentration of solvent.

<h3>The stereoisomeric forms of malic acid.</h3>

In Science, there are two (2) stereoisomeric forms of malic acid and these include:

L-enantiomers

D-enantiomers
