Read the passage from “Cruel Tribute.” Then every maiden, without looking, reached her hand into one of the vessels and drew for

th a ball, and those who took the black balls were borne away to the black ship, which lay in waiting by the shore. The young men also drew lots in like manner, but when six black balls had been drawn Theseus came quickly forward and said: “Hold! Let no more balls be drawn. I will be the seventh youth to pay this tribute.” What is the effect when Theseus volunteers? Theseus sets himself up to become the ruler of Athens. Theseus sets himself up to battle the Minotaur. Theseus sets himself up to win Ariadne’s love. Theseus sets himself up to win King Minos’s respect.

Water (2850 g ) is heated until it just begins to boil. If the water absorbs 5.53×105 j of heat in the process, what was the ini
NARA [144]

Answer is 54 °C.

<em>Explanation;</em>

We can simply use heat equation

Q = mcΔT  

 Where Q is the amount of energy transferred (J), m is the mass of the substance (kg), c is the specific heat (J g⁻¹ °C⁻¹) and ΔT is the temperature difference (°C).

Let's assume that the initial temperature is T.

Q = 5.53 × 10⁵ J

m = 2850 g

c = 4.186 J/g °C

ΔT = (100 - T)  °C     <em>Since the water is boiling, the final temperature is 100 °C.</em>

By applying the equation,

5.53 × 10⁵ J  = 2850 g  x 4.186 J/g °C  x (100 - T)  °C

(100 - T)  °C = 5.53 × 10⁵ J  / (2850 g  x 4.186 J/g °C  )

(100 - T)  °C = 46.35 °C

         T        = 100 - 46.35 C = 53.65 °C

                   ≈ 54 °C

What is S for the reaction N2(g) +O2(g) 2NO? Use G = 173.3 kJ at 303.0 K and H = 180.7 kJ. Use G = H – TS.
Rashid [163]

Given information :

G = 173.3 KJ

H = 180.7 KJ

T = 303.0 K

S = unknown (?)

By using the given formula : G = H - TS , we can calculate the value of 'S'

On rearranging the formula we get : S = \frac{H-G}{T}

Plug in the value of G , H and T in the above formula :

S = \frac{(180.7 KJ - 173.3KJ)}{303.0K}

S = 0.02442 \frac{KJ}{K}

An intravenous infusion is to contain 15 mEq of potassium ion and 20 mEq of sodium ion in 500 mL of 5% dextrose injection. Using
Studentka2010 [4]

Answer:

To supply the required ions it is necessary to inject 5,6mL of 6g/30mL solution and 131,1 mL of 0,9% solution.

Explanation:

1mEq of sodium are 59mg of NaCl and 1mEq of potassium are 75mg KCl

in intravenous infusion 15 mEq of K are:

15x75mg KCl = 1,125g of KCl

And 20 mEq of Na are:

20x59mg NaCl = 1,18g of NaCl

To supply the potassium ion it is necessary to inject:

1,125g of KCl×\frac{30mL}{6g} =<em> 5,6mL  of 6g/30mL solution</em>

And, to supply the sodium ion it is necessary to inject:

1,18g of NaCl×\frac{100mL}{0,9g} = <em>131,1 mL of 0,9% solution</em>

What stresses will shift the reaction to increase the products
AveGali [126]

Answer:

Change in molarity, temperature, volume/pressure depending on the conditions given

Explanation:

It really depends on the type of a reaction, however, we may apply general trends and see every possibility:

  • if we increase the concentration of products, then, according to the principle of Le Chatelier, the equilibrium will shift toward the formation of products;
  • if we have an endothermic reaction, increasing heat will lead a shift to the right and toward formation of products, since heat might be considered a reactant as well;
  • if we have an exothermic reaction, removing heat/decreasing temperature will lead to an increase in products, as we're removing one of our products, heat, and system will try to rebuild the amount of heat lost forming the other products as a result as well;
  • if we have gaseous substances in a reaction, an increase in pressure will shift the equilibrium to the right if we have a greater amount in moles of reactant gases compared to products, this is also known as a decrease in volume;
  • if we have gaseous substances in a reaction, a decrease in pressure will shift the equilibrium to the right if we have a greater amount in moles of product gases compared to reactants, this is also known as an increase in volume.
