Answer: Oxidation and Reduction Reactions.

Explanation: Redox Reaction is a type of reaction in which the oxidation reaction as well as the reduction reaction takes place simultaneously.

Oxidation reaction is the one in which one species loses electrons and appears as cation and reduction reaction is the reaction in which the other species accept electrons.

The one which loses electrons is known as Oxidizing Agent as it helps the other specie to accept electrons and the one which accepts electrons is known as Reducing Agent .

Every redox reaction consists of two parts, the oxidation and the reduction. Each one separately is called a half - reaction. During the redox reaction there is a transfer of electrons from the substance being oxidized to the substance being reduced. In a voltaic cell, these reactions happen in separate vessels.

A 7.00-mL portion of 8.00 M stock solution is to be diluted to 0.800 M. What will be the final volume after dilution? Enter your

amm1812

Explanation:

The number of moles of solute present in liter of solution is defined as molarity.

Mathematically, Molarity = $\frac{\text{no. of moles}}{\text{Volume in liter}}$

Also, when number of moles are equal in a solution then the formula will be as follows.

$M_{1} \times V_{1} = M_{2} \times V_{2}$

It is given that $M_{1}$ is 8.00 M, $V_{1}$ is 7.00 mL, and $M_{2}$ is 0.80 M.

Hence, calculate the value of $V_{2}$ using above formula as follows.

$M_{1} \times V_{1} = M_{2} \times V_{2}$

$8.00 M \times 7.00 mL = 0.80 M \times V_{2}$

$V_{2} = \frac{56 M. mL}{0.80 M}$

= 70 ml

Thus, we can conclude that the volume after dilution is 70 ml.

How many formula units (particles of AgNO3) are in 5.50 grams of AgNO3?

lianna [129]

Answer:

No of molcules(N)= 1.98×10^22

Explanation:

m=5.5, Mm= 167, NA= 6.02×10^23

Moles(n)= m/M= N/NA

5.5/167 = N/6.02×10^23

SIMPLIFY

N=1.98×10^22molecules
