Greeley [361]3 years ago

Answer:

1. Mediterranean Sea; 2. Aegean Sea; 3. Thames River

Explanation:

1. Transport from Spain to Italy

The Mediterranean Sea provides easy transport from the Spanish ports of Valencia and Barcelona to the Italian ports of Savona, Livorno, Civitavecchia, Salerno, and Palermo.

The Black Sea and the Volga and Danube rivers are on the eastern side of Italy, so they would not be used for such transport.

2. Importance to Ancient Greeks

Ancient Greece surrounded the Aegean Sea, so the Sea was of great importance for transport and communication be the various areas of the region.

The Black Sea and the Volga and Danube River were far from ancient Greece.

3. Asset for city of London

The city of London straddles the Thames river, which extended far into the countryside. It therefore served as a major route for bringing food and supplies to to the city.

The Seine River is in France, the Mediterranean is south of Europe, and the Atlantic Ocean is far side of the British Isles.

( HELP) The following system is at equilibrium. In which direction (right or left) will the equilibrium position shift with the
Alex Ar [27]

a) right

b) left

c) left

d) right

e) right

f) no effect

d) left

Explanation:

We have the following chemical reaction:

3 NO (g) ⇔ N₂O (g) + NO₂ (g) + 154.9 kJ

a) right, because by lowering the temperature you remove the heat generated by the reaction, and the reaction is able to generate more heat with the reaction proceeding from left to right.

b) left, because by increasing the temperature you add heat to the reaction and by doing so the reaction from right to left will be promoted.

c) left, increasing the concentration of N₂O the equilibrium will shift to left in order to consume the N₂O added.

d) right, increasing the concentration of NO the equilibrium will shift to right in order to consume the NO added.

e) right, decreasing the concentration of N₂O the equilibrium will shift to right in order to produce the removed N₂O.

f) no effect, adding a catalyst will not shift the equilibrium position, it will only modify the time in which the equilibrium is achieved and the energy required to achieve the equilibrium state.

g) left, by increasing the volume the equilibrium will shift to the part where more moles are produced (there are 3 moles on left side while in the right side there are 2 moles).

How much energy is transferred when 30.0<br> g of water is cooled from 25.0 °C to 12.7 °C.
enot [183]

Answer:

Heat transferred, Q = 1542.42 J

Explanation:

Given that,

Mass of water, m = 30 grams

Initial temperature, T_i=25^{\circ} C

Final temperature, T_f=12.7^{\circ} C

We need to find the energy transferred. The energy transferred is given by :

Q=mc\Delta T

c is specific heat of water, c = 4.18 J/g °C

So,

Q=30\ g\times 4.18\ J/g-^{\circ} C\times (12.7-25)\ ^{\circ} C\\\\Q=-1542.42\ J

So, 1542.42 J of energy is transferred.
