What is N2O5?

Dinitrogen pentoxide exists as a colorless solid that is formed when phosphorus oxide reacts with nitric acid. It is unstable at temperatures higher than room temperature and breaks down into N204, dinitrogen tetroxide, and O2, an oxygen molecule.\nAccording to Reference.com, dinitrogen pentoxide is a potentially dangerous oxidizer that was previously used as a reagent for nitration. It has since been almost entirely replaced in this capacity by NO2BF4, nitronium tetrafluoroborate.

What is an example of a mixture?

A mixture can be homogeneous or heterogeneous. A homogeneous mixture is a mixture which has the same composition and appearance throughout it. These mixtures are often referred to as solutions. The term solution is used most often when at least one of the components is a liquid. An example of a homogeneous mixture in the solid phase is a metal alloy. A heterogeneous mixture contains different substances that stay physically separate.

How do fish have babies?

In some fish, such as sharks, the embryos are nourished by a placenta-like organ until they're developed, at which time the mother births live young. Some fish, such as codfish, which release eggs and sperm into the water, don't offer their young or eggs any parental care. Others, like Siamese fighting fish, build nests to protect the eggs. Some sharks that hatch inside their mother eat their siblings and other eggs before they're born.

What is an example of a compressional wave?

A compression wave is a mechanical longitudinal wave. The longitudinal wave constitutes the movement of the compressed region of matter in one direction. The particles of which that matter consists, however, do not move along with the wave. They are displaced in the direction parallel to that in which the wave propagates.To visualize a compressional wave in a nonwave example, picture a slinky toy. The compression of the spiral rings appears to be a wave traveling from one end of the slinky to another, while individual rings simply oscillate around their original points of rest.One example of a..

How do bryophytes differ from vascular plants?

Bryophytes include mosses, liverworts and hornworts. All these groups require abundant water to live. Every plant alternates between what is known as a gametophyte stage, with only one set of chromosomes, and a sporophyte stage, with two matched sets of chromosomes. In higher plants such as ferns and angiosperms, the sporophyte is the large, leafy form. In bryophytes, this situation is reversed, with the gametophytes being the photosynthetic, more visible stage.\nThe most common type of bryophytes are the mosses. There are more than 15,000 known species of mosses. The life cycle of mosses begi..

Which states require smog checks?

Smog checks are mandatory in many states and are strictly enforced, according to the DMV. A smog test can let the car owner know if the car is burning fuel efficiently, or if the car is required to get repairs to meet legal emissions standards. Smog testing contributes to the reduction of air pollution in states where it is implemented. Air pollution has a major impact on the health and well-being of citizens. For instance, California requires car owners to get annual smog tests on vehicles. The state's vigilance has paid off by removing a large amount of pollutants from the air that Cali..

What are the ligaments of the foot?

The dorsal ligaments, located at the top of the foot, are divided into the dorsal tarsometatrsal ligaments and dorsal metatarsal ligaments. They include the dorsal talonavicular ligament, dorsal cuboideonavicular ligament, dorsal navicular cuneiform ligament and dorsal intercunieform ligament. The plantar ligaments, located at the bottom of the foot, include the plantar fascia, long plantar ligament, plantar intermetatarsal ligament, plantar calcaneonavic ligament and plantar cuboideonavic ligament. The interosseous ligaments are located between the bones in the foot and include the bifurcated..

What is the molecular weight of citric acid?

To determine the molecular weight of C6H8O7, the sum of the atomic weights of the atoms in a single molecule need to be determined. There are six carbon, eight hydrogen and seven oxygen atoms, and their atomic weights, as found in the Periodic Table of the Elements, are 12.011 g/mol, 1.00784 g/mol and 15.9994 g/mol respectively. Adding (6 x 12.011 g/mol), (8 x 1.00784 g/mol) and (7 x 15.9994 g/mol) yields 192.12 g/mol, which is the molecular weight of citric acid.

Why do earthquakes and volcanoes happen mostly in the same place?

Earthquakes are caused when tectonic plates shift and push over each other. The place where this happens is called a fault line. The shifting of the plates causes movements on the surface of the Earth that feel like an earthquake, and as the plates are constantly in motion, they naturally bump against each other over time.\n\nVolcanoes are formed when magma from the interior of the Earth works its way up to the planet's surface. The excessive movements of the plates along the Ring of Fire causes the rock to melt into magma more easily, leading to more regular volcanic eruptions.

How do you make a volcano science project?

Mix flour, salt, cooking oil and waterUsing a container, mix 6 cups of flour, 2 cups of salt, 2 cups of warm water and 4 tablespoons of cooking oil. This should create a substance that has a doughy texture and consistency.\nMold the mixture into a conePlace the soda bottle in your pan. Use the mixture you just created to make a cone shape around the outside of the bottle. Make sure the hole remains unsealed during this process.\nFill the bottlePour some of the water and food coloring into the bottle until it's almost completely full. Then, add in 6 drops of detergent and 2 tablespoons of ..
