Science Experiments

Perhaps the yellow candle contains hydrocarbons with a smaller carbon backbone. The smaller the carbon backbone, the faster the molecule (and hotter) will burn. Methane, Ethane, Propane, Butane.... Octane, Ethane (used in creation of ethanol) burn hotter than octane, but are all used for fuel. The larger (longer) the carbon backbone, the less volitile the hydrocarbon. See Web Links See the Web Links for "Wikipedia: List or inorganic compounds" to the bottom for the answer. Any chemical compound without a carbon is an inorganic compound.

In general, a compound that contains a carbon atom is an "organic" compound. There are exceptions: oxides of carbon like carbon dioxide and carbon monoxide; salts of carbon, like cyanide, cyanate, and thiocyante. See http://en.wikipedia.org/wiki/Inorganic_compounds_by_element for a detailed listing inorganic compounds by element.

A few examples of common inorganic compounds:

Carbon Dioxide, CO2

Hydrogen Chloride, HCl (when dissolved in water becomes Hydrochloric acid, aka stomach acid) Sulphuric acid, H2SO4

Everything you need to conduct the experiments you are interested in.

A basic chemistry lab would consist of test-tubes, burettes, pipettes, chemicals, washing sinks, crucibles, tripod stands, Bunsen burners, etc.

A biology lab might consist of petri dishes, agarorse gel, PCR machines, etc.

A physics lab might consist of retort stands, springs, weights, thread, etc.

The more complex the experiments the lab is intended for, the more sophisticated the equipment (thought not necessarily more). For example, you would not expect electron microscopes to be found in a primary school laboratory.

The answer to this question most likely has to do with the albedo of crayon (wax, charcoal, etc). Albedo is the extent to which an object diffusely reflects light from light sources, measured as a ratio. The lower the albedo, the more light/energy is absorbed into the object. Since darker colored objects absorb more energy, the albedo of a darker crayon is probably lower than the albedo of a lighter crayon. This means the darker crayon, while absorbing more energy, will heat up faster than the lighter crayon.

This is why snow around a tree typically melts much faster and earlier than snow with nothing around it -- because of the tree bark's albedo is much lower than snow/ice and thus can absorb more energy faster, and heat up whatever is around it quicker.

The excretory system removes liquid wastes.

Metal transfers heat fastest. In fact, heat flows from a hotter body to a colder body when the two bodies are brought together. This transfer of energy usually results in an increase in the temperature of the colder body and a decrease in that of the hotter body. A substance may absorb heat without an increase in temperature as it changes from one phase to another that is, when it melts or boils.

Water manages to get into a crack in a rock, and with cold temperatures, freezes. When transferring from a liquid to a solid, the molecules of water expand by crystallization, widening the crack in the rock.

To start, the ball has potential energy. When you put it on a ramp (any size) its potential energy is turned into kinetic energy. When you put it on a higher ramp, there is more potential energy, because the ball is higher up. Think about going to the top of a tall building. You start at the lobby, and let's say you take the elevator to the penthouse. You may notice feeling heavier. The same thing happens to the ball, and that's why balls on higher ramps go farther.

You get aspects of each trait displayed. Like, if one cat had a solid colored orange fur, and it's mate was brown, you could get a mottled cat. Or if one parent has brown eyes, and the other green, hazel eyes could occur.

1 gram = 1,000 milligrams

20 grams = 20,000 milligrams

I am a chemist at the university of south carolina and i have been experimenting on the melting point of oxygen. Oxygen at its melting point acts very stable . it dosnt act uncontrolable.

there is only one manipulated varable in an experiment otherwise it would not be a controlled experiment

A type of mixture in which different materials are spread out unevenly is known as a heterogeneous mixture. It is a combination of substances with no uniform composition or properties.

it is the condensed water vapour and gas.

Even if objects did absorb energy continuously, since everything is made of smaller things, when they reached a certain temperature they would simply dissociate into their constituents. So instead of 1 very hot object you get several moderately warm objects.

The outward appearance of a trait is called a phenotype.
the alternative form of a gene is called an "allele." Alleles occur at the same locus on homologous chromosones, thus govern the same trait. This term is sometimes used sysnonymously with "gene."

Yes the sun is where algae gets its energy.

Well, there are two poles to a magnet. A negative one and a positive one. Since metals are good conductors of charge and the paper clip is a metal object, they will attract. The charge of the paperclip is opposite the charge to one of the poles of the magnet.

Ah, I actually asked the same exact question about 3 years ago! I did a scientific experiment in my science class and to cut it short, glass. But your gonna have to do the rest of the work on your own. ;)

Mitochondria because this releases energy from stored food molecules which is used for power growth, development, and movement. muscle cells have a greater demand for this than any other body cells.

The back and forth movement of an object is called undulation, more commonly referred to as swaying or rocking. An object's undulation is measured in cycles (e.g. the number of times an object moves back and forth) per unit time. Ex. the undulation of a pendulum (such as in a grandfather clock) is usually measured in cycles per second.

A1 Because water is a solvent, and as long as the material, in this case salt, has less density than the liquid itself, it should sink. But, other solutes like sugar, are denser and water, and will simply sink.

A2 Strictly, there are many many salts, and common table salt, NaCl is the one we meet most commonly. This dissolves readily in water as you remark.

Copper Sulphate 'bluestone' is another salt. Some salts are essentially insoluble, such as many of the Mercury salts - especially the Mercurous ones.

The overall charge of a nucleus is positive.

The nucleus is consisted of protons and neutrons. Protons have a positive charge and neutrons have a neutral charge. Electrons have a negative charge but are located in the shell orbiting the nucleus, so their charge is not included in the nucleus' charge. Since the only particles in the nucleus either have a positive or neutral charge, the nucleus will always be positive.

both. the clothes becomes wet which is a physical change and the chemicals in the soda going through the fabric of your clothes is a chemical change.
