Answer:

0.11M

Explanation:

What is the Molarity of a Ca(OH)2 solution if 30.0mL of

the solution is neutralized by 26.4mL of 0.25M HCI solution?

1L (1000 ml) of the HCl contains 0.25 moles of H ion

26.4 ml contains ( 26.4 X0.25/1000) moles of H ion ion

=0.0066 moles H ion

2HCl +Ca (OH)2-----> 2H2O +CaCl2

SO 2 H IONS NEUTRALIZE 1 Ca(OH)2 MOLECULE

00066 moles H ion neutralize 0.0033 moles Ca(OH)2

the 0.0033 moles are distributed over 30 ml, so the concentration of the

Ca(OH)2 IS 0,0033/(30/1000) =0.11 moles/liter or 0.11M

Silver nitrate solution reacts with calcium chloride solution according to the equation: 2 AgNO3 + CaCl2 → Ca(NO3)2 + 2 AgCl All
HACTEHA [7]

Answer:

14.33 g

Explanation:

Solve this problem based on the stoichiometry of the reaction.

To do that we need the molecular weight of the masses involved and then calculate the number of moles, find the limiting reagent and  finally calculate the mass of AgCl.

                      2 AgNO₃   + CaCl₂    ⇒   Ca(NO₃)₂   + 2 AgCl

mass, g                  6.97        6.39                                     ?

MW ,g/mol         169.87      110.98                                  143.32

mol =m/MW           0.10         0.06                                    0.10

From the table above AgNO₃ is the limiting reagent and we will produce 0.10 mol AgCl which is a mass :

0.10 mol x 143.32 g/mol = 14.33 g

How does mixture relate to life​
masya89 [10]

Answer:

For example, when we bake a cake, it's a result of a mixture of eggs, flour, sugar, and other ingredients.  Any time two or more items are combined, a mixture is formed. Sometimes, the different parts of a mixture can be separated into individual entities. Other times, they're married for as long as they exist.
