What is the Ea for the exothermic reaction A)332.6 kJ B)-85.1 kJ C)251.0 kJ D) -251.0 kJ
Lina20 [59]

Answer:

Option C. 251 kJ

Explanation:

The activation energy (Ea) of a given reaction is the minimum energy that must be overcomed for reactant to proceed to product.

The activation energy (Ea) can be obtained from an energy profile diagram by simply calculating the difference between the energy of the activation complex (i.e the peak) and the energy of the reactant.

Thus, we can obtain the activation energy for the reaction above as follow:

Activation complex = 332.6 kJ

Energy of reactant = 81.6 kJ

Activation energy =?

Activation energy = Activation complex – Energy of reactant

Activation energy = 332.6 – 81.6

Activation energy = 251 kJ

Therefore, the activation energy of the reaction is 251 kJ

An archaeologist finds 14C in a sample of material to be decaying at 20 Geiger Counter clicks per second. A modern equivalent sa
Kay [80]

Answer:

17188 years

Explanation:

Recall the formula;

0.693/t1/2 = 2.303/t log(No/N)

t1/2 = half life of 14C

No = initial activity of 14C

N = activity of 14C at time t

t = age of the sample

Substituting values

0.693/5730= 2.303/t log(160/ 20)

1.21 * 10^-4= 2.0798/t

t = 2.0798/1.21 * 10^-4

t = 17188 years

At 82K, a gas has a volume of 4.60L. What would be the volume of the gas at 70K?
Oliga [24]

Answer:

V₂ = 4.0L

Explanation:

Decreasing temperature => Decreasing Volume (Charles Law)

For a given volume, use a temperature ratio that will give a smaller volume.

Volume at lower temp = 4.6L(70K/82K) = 4.0L ... Using (82K/70K) would give a larger volume => contrary to temperature effects on gas volumes when pressure and mass are kept constant.

Pressure effects on Gas Volumes:

Note: The same idea is applied to pressure effects on gas volumes also except that changes in pressure affect gas volumes indirectly. That is, an increase in pressure => decrease in volume, or a decrease in pressure => increase in volume. Boyles Law => V ∝ 1/P.

Given a gas volume of 4.60L at 760mmHg, what is volume at 848mmHg?

Increasing pressure => Decreases Volume (Boyles Law)

For the given volume use a pressure ratio that will give a smaller volume.

Volume at higher pressure = 4.6L(760mm/848mm) =4.1L. Using (848mm/760mm) would give a larger volume => contrary to pressure effects on gas volume when temperature and mass of gas are kept constant.

Students at Gonzaga University were attempting to make barium phosphate by precipitation when mixing solutions of barium chlorid
Solnce55 [7]

Answer:

Explanation:

3BaCl₂(aq)        +    2Na₃PO₄(aq)   =   Ba₃(PO₄)₂    +    6NaCl(aq)

3 x 208 g = 624 g    2 x 164 g = 328 g  

 328 g  of Na₃PO₄ reacts with 624 g of BaCl₂

.611 g  of Na₃PO₄ reacts with 624 x .611/328 g of BaCl₂

624 x .611/328 g = 1.16 g of BaCl₂

BaCl₂ available is .504 g which is less than required .

Hence BaCl₂ is limiting reagent .
