#2 Compare the number of moles of each element on both sides of the reaction. Write the results in the following space.
vredina [299]

Explanation:

This is the photosynthesis equation in which green plants manufacture their food.

During photosynthesis, green plants combine carbon dioxide with water to produce glucose and oxygen gas.

 The equation is as shown below:

    6CO₂    +     6H₂O        ⇒         C₆H₁₂O₆      +     6O₂

This reaction is a typically balanced equation and by all means, we must have the same number of moles of reactants and products.

Solving:

     Reactants                                                            Products

Elements        Number of moles                                Number of moles

   C                               6                                                           6

   H                                12                                                         12

    O                               18                                                         18

Using the coefficients, one should be able to determine the number of moles of each element.

What is the molarity of a solution made by dissolving 21.2 g of a sodium hydroxide (NaOH) in enough water to make 7.92 L of solu
Masja [62]

Formula for molarity is

Molarity=moles of solvent/solution in liters

In given data

NaOH is 21.2g which is needed to be convert in moles first

As no.of moles=mass in gram/molar mass

Molar mass of NaOH is 39.997g/mol

Putting in formula for mole.we get

No of mole = 21.2g/39.997gper mole

= 0.530mole

Now put these values in molarity equation, we get

Molarity =moles of NaOH/ solution in liter

= 0.530/7.92

=0.067M NaOH
