Baking soda (NaHCO3) can be added to a fruit mix solution to create a carbonated drink. An example is the reaction between bakin
Gwar [14]

The molarity of the solution is the moles dissolved per liter. The volume of 0.8 M citric acid solution will be 74.16 mL.

<h3>What is molarity?</h3>

Molarity of the solution is the concentration that is given by the moles of the solute that are dissolved to make the solution in liters.

The chemical reaction between baking soda and citric acid is shown as:

C₆H₈O₇ + 3NaHCO₃ → Na₃C₆H₅O₇ + 3H₂O + 3CO₂

Given,

Molarity = 0.8 M

Mass of baking soda = 15 grams

The molar mass of baking soda = 84.007 g/mol

Moles of baking soda = 15 ÷ 84.007 = 0.178 moles

From the reaction, it can be said that 3 moles of baking soda are required to react with 1 mole of citric acid. So, 0.178 moles will need, 0.059 moles.

The volume of citric caid needed is calculated as:

M = moles ÷ volume

Volume (L) = 0.059 ÷ 0.8

= 0.07416 L

Volume is converted into mL as:

1 L = 1000 mL

0.07416 L = 74.16 mL

Therefore, 74.16 mL is the volume of citric acid needed.

PLEASE HELP I NEED IT!!!!!
galina1969 [7]
Answer:
Molarity = 2.3 M

Explanation:
Molarity can be calculated using the following rule:
Molarity = number of moles of solute / volume of solution

1- getting the number of moles:
We are given that:
mass of solute = 105.96 grams
From the periodic table:
atomic mass of carbon = 12 grams
atomic mass of hydrogen = 1 gram
atomic mass of oxygen = 16 grams
Therefore:
molar mass of C2H6O = 2(12) + 6(1) + 16 = 46 grams
Now, we can get the number of moles as follows:
number of moles = mass / molar mass = 105.96 / 46 = 2.3 moles

2- The volume of solution is given = 1 liter

3- getting the molarity:
molarity = number of moles of solute / volume of solution
molarity = 2.3 / 1
molarity = 2.3 M

Hope this helps :)

An ionic bond occurs between what particles?
atroni [7]

Answer:

A positive and negative ion.

Explanation:

Ionic bond:

It is the bond which is formed by the transfer of electron from one atom to the atom of another element.  

Both bonded atoms have very large electronegativity difference.

The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.

For example:

Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion.  Sodium have one valance electron while chlorine have 7 valance electrons. In order to complete the octet chlorine require one electron while sodium need to lose its one electrons. That's why when both atom combine sodium lose its electron and becomes positive ion i.e cation while chlorine accept its electron and becomes negative ion called anion and bond between them is ionic bond.
