Dmitry_Shevchenko [17]

Answer:

Increase the concentration of the solution

Explanation:

Increasing the solute would increase the concentration. Increasing the solvent would decrease the concentration. For instance, if your lemonade was too tart, you would add more water to decrease the concentration

Laura and Jess observed two points, P and Q, on a number line. A number line is shown from negative 2 to positive 2 with increme
sweet-ann [11.9K]

Answer:

P is 5 ticks to the left of 0, so it would be -5/8

Q is 5 ticks to the right of 0, so it would be at 5/8

an absolute value turns a negative number into a positive number

so absolute value of  P located at -5/8 = 5/8

this is the location of point Q

Jimmy said that the absolute values of the numbers represented by the two points are the same.  

so Jimmy is correct

25.0 mL of an HBr solution were titrated with 29.15 mL of a 0.205 M LiOH solution to reach the equivalence point. What is the mo
krok68 [10]

HBr reacts with LiOH and forms LiBr and H₂O as the products. The balanced reaction is

LiOH(aq) + HBr(aq) → LiBr(aq) + H₂O(l)

Molarity (M) = moles of solute (mol) / volume of the solution (L)

Molarity of LiOH = 0.205 M

Volume of LiOH = 29.15 mL = 29.15 x 10⁻³ L

Hence,

moles of LiOH = molarity x volume of the solution

= 0.205 M x 29.15 x 10⁻³ L

= 5.97575 x 10⁻³ mol

The stoichiometric ratio between LiOH and HBr is 1 : 1.

Hence,

moles of HBr in 25.0 mL = moles of LiOH added

= 5.97575 x 10⁻³ mol

Hence, molarity of HBr = 5.97575 x 10⁻³ mol / 25.00 x 10⁻³ L

= 0.23903 M

≈ 0.239 M

Hence, the molarity of the HBr is 0.239 M.

Be sure to answer all parts. From the following reaction and data, find (a) S o of SOCl2 (b) T at which the reaction becomes non
EleoNora [17]

Answer:

Explanation:

Hrxn = -245.6-296.8+396+50.0 = -96.4 (kJ/mol)

Since Grxn = Hrxn - T*Srxn, where T = 298.15K, we have:

Srxn = (Hrxn - Grxn)/T = (-96.4+75.2)× 1000÷298.15 = -71.1 (j/K mol)

Since: Srxn = Sf (SO2) + Sf (SOCl2)- Sf (SO3) - Sf (SCl2),

or: -71.1 = 248.1 + Sf (SOCl2) - 256.7-184,

Sf (SOCl2) = 256.7+184-71.1-248.1 = 121.5 (J/mol*k)

In order to find T such that Grxn = Hrxn - T*Srxn >= 0. since Hrxn is negative and Srxn is positive, Grxn will always be less than zero. Therefore there won't be a temperature point at which the reaction is going to be non-spontaenous
