When a chemical reaction occurs,
OA) the atoms involved remain the same
B) the molecules involved remain the same
C) the atoms arrange themselves into new kinds of molecules
OD) the substances before and after are the same

Answers

Answer 1

Answer:

C) the atoms arrange themselves into new kinds of molecules

Explanation:

To prove that a chemical reaction occurs, the atoms arrange themselves into new kinds of molecules.

Chemical reactions involves bond re-arrangement to give a new set of bonds in the products.

Most chemical reactions occur due to loss, gain or sharing of electrons. This makes the species in the products and reactants have a stable configuration.

The major industrial nations of the world, like the United States and China, are also the world's largest
contributors to carbon emissions. They are not the only ones, though. If this is a global problem, who
should be responsible for working to correct this problem and why?

Answers

Answer:

This problem should be worked on by the most developed countries as they have the biggest capacity, and after they get on the right way to help the developing countries and show them the way as to how to do it as well.

Explanation:

The carbon emissions that humanity is releasing into the atmosphere can not be attributed to only a few countries, but to most of the countries in the world. All countries that have some kind of industry contribute to the problem, though some countries much more than others.

In order for carbon emissions to decrease there should be a global collaboration. The most developed countries because they have the most finances and resources should lead the way and come up with solutions, and once they do this to help the developing countries with it so that they can also stop the carbon emissions.

Many countries are already on the right path, namely Germany, the Netherlands, France, the Scandinavian countries. The two biggest economies though, the US and China don't even want to hear about this because of their race for economic dominance, so it seems that reasoning the governments of these two countries will be the most important step for global turnaround.

A mountain glacier begins to melt due to warmer air temperatures, exposing some dark gray rock once covered by the glacier. Explain how this could trigger a positive feedback in which the exposed rock causes more melting of the mountain glacier. Support your response using your knowledge of albedo, the albedo values provided below, and scientific reasoning.

Answers

The glacier has a high albedo as the melting of ice in the summers produces a positive mechanism.

How does glacial melt lead to positive feedback ?

Over the time period, the ice melts and this leads to exposure of the dark greyish rocks and creates more melting from mountain glacier. The reflections from glacier snow are highest as the ice absorbs lesser sunlight helps to keeps the surface cooler.  

Thus reflecting back most of the sunlight, in the summer months due to the agents of erosion the ice begins to move, and this leads to the positive feedback mechanism which melts glaciers.

What is the Suez Canal, and why is it so important for shipping?

Answers

Answer:

The Suez Canal is a man-made waterway connecting the Mediterranean Sea to the Indian Ocean via the Red Sea. It enables a more direct route for shipping between Europe and Asia, effectively allowing for passage from the North Atlantic to the Indian Ocean without having to circumnavigate the African continent.

Explanation:

From Google

Answer:

Let's look at the route between two major shipping ports, one in Europe (Hamburg) and one in Asia (Singapore).

Hamburg to Singapore via the Cape of Good Hope on the southern tip of Africa: 11,864 nautical miles

Hamburg to Singapore via the Suez Canal: 8,377 nautical miles

(A statute mile is 5,280 feet in length; a nautical mile is 6,076.11549... feet in length.)

That is a difference of 3,487 nautical miles. For the average ship steaming at 18 knots (18 nautical miles per hour), that's 193.72 hours or just over 8 days. So the Suez Canal literally saves over an entire week off of the transit from Europe to Asia.

That means money.

Less money that has to be spent on fuel to get the ship there, food for the crew for those 8 days not spend at sea, and less cost to shippers to send those good.

It also means more goods transported in a year, so manufacturers make more, shippers make more, and the consumer gets more and gets it faster.

Without the Suez Canal, everything increases in price. Not to mention the Cape of Good Hope is a notoriously dangerous shipping route with frequent and bad storms. That means not only does it take longer, but it's more dangerous.

A shorter route, a faster route, a less dangerous route, and a less expensive route. What's not to like?

(You can use this same analogy for the Panama Canal and transits around Cape Horn and South America)

Answers

Answer:

d i think hope it helps:)

Explanation:

Answer:

D. They all consist of large pieces of the lithosphere.

Explanation:

The "tectonic plates" are large pieces of the lithosphere, thus, they are also called "lithospheric plates." They're not of the same size nor shape. They come in various sizes that are massive and have irregular shapes. They are not only found under continents but some can also be found under the ocean (oceanic lithosphere).  

So, this makes choice D correct.
