Determine the molarity of a solution formed by dissolving 4.00 moles of KBr in enough water to yield 3.00 L of solution.

Molarity (M) is the numer of moles per liter (mol/L)

Both are already given:
mol = 4.00 moles of KBr
L = 3.00 L H2O (water)

Plug them both into the equation:
<u>4.00 mol KBr </u> = 1.33 M KBr (1.33 because of sig figs)<u>
</u>3.00 L H2O <u>
</u>

To find time, t, the age of the universe, you must first isolate the variable t. Rewrite the velocity equation v = d / t so that
Alex17521 [72]

Answer:

t = d/v

Explanation:

All you have to do is the inverse operation so that you multiply by "t" and it will be on the side with the "v" then you divide the v and it will be under the "d" so time = distance/ velocity (speed)

8. How much enthalpy/heat is transferred when 0.5113
Gennadij [26K]
First convert to moles:
0.5113 g / 17 g/mol = 0.0301 mol

Now create a ratio based on the reaction provided to solve for the unknown:

4 NH3 / -905.4 kJ = 0.0301 mol NH3 / x kJ
x = -6.808 kJ

g Calculate the [OH-] from the results of your titrations. Explain your calculations2. Calculate the [Ca2+]. Explain your calcul
RideAnS [48]

Answer:

Explanation:

*Since the titration is between the strong acid HCl and the strong base Ca(OH)2, the pH at the equivalent point should be 7. On interpolation, we will obtain that 9.50mL and 9.82 mL of HCl is required to completely neutralized the given Ca(OH)2 solution.

*pH at the equivalence point =7

we know that pH + pOH = 14

Hence pOH= 14-7=7

pOH= -log(OH-)

The concentration of OH-= 10-pH= 1X10-7 M

One reason for the low solubility may be the higher reaction temperature, Another reason is the common ion effect.

Why might Marie Curie have been motivated to teach the children of beet workers?
pav-90 [236]

Marie curie worked as a governess and she was awarded noble prize for her discoveries.

Explanation:

When Marie curie worked as a governess for three years her employer allowed her to teach reading to the children of peasant workers at his beet sugar factory. This was banned under Russian rule. During that time she studied chemistry lessons from her father by mail.

Marie curie was awarded the Noble prize in chemistry for her discoveries and studies of elements radium and polonium. She is the only women who is awarded the Noble prize twice.

She made her first research into the treatment of tumors with radiation and founded a Curie institutes, that are important medical research centers.
