What is the chemical formula for snow?

A snowflake is either an individual snow crystal or a series of snow crystals stuck together; therefore, its chemical formula is the same as water. Snowflakes have symmetrical patterning, unlike sleet particles which do not have this type of patterning. The ice crystals that make up snow are a six-fold symmetrical pattern. They resemble hexagonal prisms. As snowflakes grow, they tend to branch out and make more complex shapes than simple hexagonal prisms.

Why is the circulatory system important?

The main organ of the circulatory system is the heart, which is responsible for pumping oxygenated blood throughout the body. Without the heart, a human cannot live. Other parts of the circulatory system include the blood and blood vessels, such as arteries and veins. Arteries are responsible for carrying blood away from the heart, and veins are responsible for carrying blood toward the heart.\nCapillaries are also blood vessels; they are the structures that connect arteries to veins throughout the body. The blood itself has many different types of cells that help the body function, such as re..

Where can you find a price guide for recycling aluminum can tabs?

Aluminum can tabs can be sold by the pound or ton for recycling. One pound of scrap aluminum requires over 1,200 can tabs. Scrap metal prices, including aluminum can tab prices, fluctuate constantly, so check an up-to-date chart such as the one on MetalPrices.com to determine the current scrap value. Some scrap metal places pay more per pound for larger quantities of metal, since the actual value of scrap aluminum is minimal. Some companies that accept scrap metal pay the same scrap aluminum price for the tabs and their associated cans.\nOrganizations that collect tabs to help offset expenses ..

What is the importance of segregation of wastes?

Biodegradable wastes are quickly broken down by microorganisms in normal environmental conditions. This category is mainly food scraps. It is further split into animal-derived and plant-derived waste. Animal waste must be handled separately from plant waste, especially if the food waste is intended for animal feed. In addition, the organisms that help break down biodegradable waste are different for animals and plants, with animal-derived waste posing a greater health risk.\nNon-biodegradable waste is the source of much of humanity's waste disposal problem. Paper, metals, glass, plastic a..

What is a Tornado Intercept Vehicle?

The original TIV was a 1997 Ford F-Super Duty truck which was armored with 1/4-inch steel plate and fitted with bullet-resistant polycarbonate windows. It was featured on the Discovery Channel's TV show "Storm Chasers." Casey replaced this vehicle with the TIV2, a Dodge Ram truck converted to six-wheel drive and fitted with similar armor as well as hydraulic skirts which deflect wind away from the TIV2 and protect it from debris. The TIV2 was the vehicle that drove into the tornado in May 2013.

What is the word equation for neutralization?

When sodium hydroxide reacts with hydrochloric acid, the products formed are water and sodium chloride. Sodium chloride is common or cooking salt. Similarly, when magnesium hydroxide reacts with sulphuric acid, the products formed are water and magnesium sulphate. When aluminium hydroxide reacts with nitric acid, the products formed are aluminium nitrate and water.

Why do ice cubes float to the top of a glass of water?

Ice's expansion at its freezing point is due to the polar structure of water molecules. In the liquid phase, water molecules are always in motion and can be packed closely together. As the temperature drops, however, the molecules begin to form hexagonal crystals. The hydrogen bonds created in these crystals arrange the molecules in such a way that more space exists between them than in the liquid phase, resulting in an expansion of around 8.3 percent in volume. Since the water the ice displaces now weighs less than the ice itself, ice is buoyant and floats.\nThis unique property is impor..

How wide is lightning?

The air temperature in the core of a lightning bolt is estimated to be a staggering 54,000 degrees Fahrenheit. There are an estimated 1.4 million flashes of lightning each year on Earth. Lightning is typically produced from cumulonimbus clouds with a base 1 mile above ground and a top 9 miles above ground. The main types of lightning discharges take the form of being either cloud to ground, cloud to cloud or cloud to air.

Is nitrogen harmful to humans?

Decreased thyroid function and vitamin A shortages are both caused by nitrate. Nitrite reacts with hemoglobin in the blood, causing it to not carry oxygen as well. Both nitrates and nitrates cause the formation of nitroamines, which are known carcinogens.\nWhile there are negative consequences of nitrogen, it is an important molecule within the human body that functions in the cardiovascular, immune, and central and peripheral nervous systems.

What are some retailers that sell nitric acid?
