If the power is out long enough even the city folks will run out of water. Many homes are all electric, so as soon at the lights are out they have no heat, no hot water and they can't cook. ... If the power is out, gas stations can't pump gas. Once generators run out of gas, those people will be in the dark too.

Answer:

<u>Living with no electricity might not be as easy as you may think and you not realise how many items in your home rely on it to function.</u>

Electrically managed technologies supply us with many things, such as heat, food, water, transport, energy, entertainment and communication.

Electricity allows us to power the technology we use every day.

If you plan on trying to live without electricity, you will no longer be able to turn on the central heating in your home, use the toilet, preserve food in your fridge/freezer or have clean running water.

Despite surviving thousands of years without it before, we have come to depend on it to complete our everyday tasks and have built our lives around it.

The Internet goes down.

A container of gas is heated from 250 k to 303k. What is the new pressure if the initial pressure is 880kpa? (Assume constant vo

Anna [14]

So this is p1 over t1 = p2 over t2. So you do 880/250=x/303 and then cross multiply and divide

In the reaction Zn H 2SO 4→ ZNSO4 + H2, which, if any element is oxidized

Sedbober [7]

Answer:

I hope this answer is correct

Explanation:

This is an oxidation-reduction (redox) reaction:

Zn0 - 2 e- → ZnII (oxidation)

2 HI + 2 e- → 2 H0 (reduction)

Zn is a reducing agent, H2SO4 is an oxidizing agent.

Which of the following sites has volcanoes related to subduction? A is on an island arc, B is in the Andes, C is near Hawaii, D

scoray [572]

Answer:

A is on an island arc,

B is in the Andes

Explanation:

The subduction region is referred to as the subduction zone. When a plate slips underneath another, it forms a trench. Earthquakes resulting from the plate panelling often result in magma spilling across the underwater volcano trench. Island arcs are vast chains of active volcanoes with strong seismicity located along the converging tectonic plate borders. Much of the islands arcs emerge from the oceanic crust and also have originated from fall of the lithosphere into the mantle across the subduction zone. In the Andes mountain range, Under the South American plate the Nazca plate is subducting.
