Balance this equation. If a coefficient of "1" is required, choose "blank" for that box.

C + Fe ₂ O ₃ → CO ₂ + Fe

the respiratory system brings oxygen to the circulatory system, which delivers oxygen to the muscular system

Answer:

Answer: Think of a thunderstorm, sometimes it depends on the magnitude of a push or pull to move an object even without touching it. When a object is sitting still, it means the normal force and the gravitational force are balanced, when one force becomes greater, it takes over.

Explanation:

I'm new to brainly but I hope I could help!

Answer: technically it is chemical and physical change

Explanation: chemical bc it’s burning and physical bc it’s going from a log to ashes

Answer:

C! New substances are formed.

Explanation:

The burning log will release carbon dioxide, which is a new substance that was never there in the first place.

Answer:

If I were to be a scientist, I'd be a botanist. A botanist is a scientist who studies plants. For example, they study many different aspects like their genetic, physical structure, and the distribution. They also study the relationship between plants and their different environments.

I would choose to be a botanist, because they help save our plants which are very important. They also help with telling others what exactly causes pollution and possible ways to stop it. Botanist also help with providing human resources like food. Without botanist, we would have a lot less of resources that we use in everyday life.

I can see my life as a botanist in many different ways. I might be put in the chemical based section or I might be put in the analysis of plants. Overall if I were to see myself as any kind of scientist, It would have to be a botanist.

Answer:

A wave e transports energy without transporting matter

Answer:

the answer is A. a wave transpory energy without transporting matter

Answer:

"Yes," a moving skateboard has energy.

When the skater seems to be in motion or throughout a movement, the potential energy converts itself into the kinetic form of energy, and then it becomes potential energy again.

Furthermore, somewhere after every movement, the same skateboarder was around a similar height, — in other words thus every time it is equally powerful.

The response is thus the right one.

Explanation:

Answer: the first paragraph is rain forest biome and the 2nd one is arctic tundra biome and finally the last paragraph is ocean or marine biome

Explanation:

rain forests have warm temperatures and include alot of animals and plants , artctic tundra biome includes cold temperatures ice stuff and all that and ocean or marine biome is pretty much just the ocean with seals , whales and marine life yk.

Answer:

Table sugar has more calories than aspartame. A teaspoon of table sugar (4 grams) contains approximately 16 calories, while a teaspoon of aspartame (0.5 grams) contains only 0.4 calories. This is because table sugar is a carbohydrate and contains four calories per gram, while aspartame is a non-nutritive sweetener and is virtually calorie-free.

Answer:

+6.

Explanation:

So, a chromium atom here has an oxidation number of +6.

Seafloor spreading is simply the idea that volcanic activity forms new oceanic crust.

In order to understand what seafloor spreading is in depth, it's important that we understand a few concepts and terms.

If we can understand these terms, we can easily comprehend what seafloor spreading is.

If we take a look at the attached image, the image represents what occurs during sea floor spreading. First we must note that sea floor spreading occurs in mid ocean ridges. Because we know that mid ocean ridges is a continuous range of underwater volcanoes , we know that the mid ocean ridges are formed on divergent boundaries (as volcanoes under water are formed by divergent boundaries) . As we know, at divergent boundaries, the tectonic plates move away from each other. As the tectonic plates move away from each other, magma pushes itself up and as the magma touches the water it cools and hardens forming the crust as shown in the image. (Note that this takes several years to happen)

Answer:

animals unlike us adapt faster to heat/cool weather or water

Explanation: Let's use fish as an example because that's the main water pet, so when you get a new fish and you have to put it in the water for about let's say 15 minutes. It's so it can adapt to the water. Water for us needs to be hot enough for us to actually feel the heat so therefore animals can adapt not only faster to heat but to cool air/water a lot faster than we can. I don't know if this helps or makes sense but it's what I know and have seen :P

Hope this helps. Can u give me brainliest

Explanation:

Answer:

If you are looking for like a drawing say less.

Answer:

The fact that hot air rises and cold air sinks.... Because Gases move from high-pressure areas to low-pressure areas. And the bigger the difference between the pressures, the faster the air will move from the high to the low pressure. That rush of air is the wind we experience.

Answer:

It is the first option

Why?

Because hot air rises and cold air rushes to land which causes wind. This type of wind is called land breeze. The thing is that lower the pressure, higher the wind speed

This is why you see with a barometer in storms that the air is in low pressure.

Answer: The mass of silver is 1.19 X 10^14 M g

Explanation: The volume of the truck is 402 cubic feet or 1.138 x 10⁷ mm.

The density of silver is 10.49 g/mL.

We need to find the mass of silver that will fit in this moving truck. Density equals mass divided by volume. So,

M=119376200 g  1 gram=10⁻⁶ Megagram 119376200= 1.19 X 10^14 Mg hence the mass of silver is 1.19 X 10^14 M g hopefully this will help you please mark me as brainlist

Answer: Heat\pressure control

Explanation: In order to create metamorphic rock, it is vital that the existing rock remain solid and not melt. If there is too much heat or pressure, the rock will melt and become magma.

Answer:

It also helps them understand how life works. It even helps them predict how new materials will behave. In 1869, Dmitri Mendeleev, a Russian chemist, proposed the periodic law and his first periodic table. He published this periodic table two years later in a textbook, The Principles of Chemistry.

Explanation:

Answer:

Dmitri Mendeleev, To summarize, the periodic table is important because it is organized to provide a great deal of information about elements and how they relate to one another in one easy-to-use reference. The table can be used to predict the properties of elements, even those that have not yet been discovered
