Science Experiments

Your seed crystal could be anything.

However, if you are trying to grow a "pure" crystal then you should choose something that is not going to be a problem with your final compound. For example, using a pure form of the crystal itself.

So seed salt water with SALT. But you might try a grain of salt to seed other crystals too.

J. J. Thomson experimented with cathode rays and discovered the electron, leading to the development of the plum pudding model of the atom.

J.J. Thomson is best known for his experiment with cathode rays, where he deduced the existence of negatively charged particles (electrons) in atoms. By measuring the deflection of these rays in a magnetic field, Thomson was able to determine the charge-to-mass ratio of the electron.

Adding vinegar to your dog's water will not prevent it from freezing. To prevent dog water from freezing, consider using a heated water bowl or changing the water frequently to ensure it does not have a chance to freeze.

Active transport requires energy because you are going against a gradient. Active transportation moving from low to high concentration, while passive transportation such as osmosis and diffusion go from high to low concentration.

One example of passive transportation is a river. Floating downstream does not require any energy. You are simply moving with the gradient. If you wanted to go upstream, you would have to paddle. This requires an input of energy similar to active transport.

yeah.. Tap water will evoporate faster since Carbonated water is usually containing salts, charged under pressure with purified carbon dioxide gas, used as a beverage or mixer which make it or requires much heat. While the Tap water which Water drawn directly from a tap or faucet can evaporate quickly.

I'm guessing you are asking about the SIX noble gasses.

They are very inert with respect to reactivity. However could potentially be dissolved in some solvents. Otherwise you would have to consider the basic polar/non polar properties. Like Methane, Ethane, Propane, Butane will all be more soluble in non-polar substances such as hexane, octane, pentane, benzine, toluene, etc.

Your Noble Gasses are:

Helium
Neon
Argon
Krypton
Xeon
Radon

Notes indicate that Helium is found in portions of approximately 2 nano-moles per kg of seawater, and that the other Noble Gasses are somewhat more soluble with Xeon being about 5 times more soluble than Helium.

There are many different things that are measured and tested by the data collected in an experiment. Color changes are one thing that can be measured and tested for example.

Hidden Calories In Human Beings!!!

Swallowing aluminum foil or small electronic components can cause a short circuit in the mouth, resulting in a spark that may resemble lightning. However, this is extremely dangerous and should not be attempted as it can cause serious injury, including burns and internal damage. It is not safe or recommended to try to create lightning in your mouth.

Rutherford's gold foil experiment was successful because it demonstrated that atoms have a concentrated nucleus with a positive charge. By observing how alpha particles scattered off the gold foil, Rutherford concluded that atoms are mostly empty space with a small, dense nucleus at the center.

The melting point of the epoxide of benzalacetophenone, commonly known as benzalacetophenone oxide, is approximately 90-95 degrees Celsius.

Yes, a golf ball typically has a lower mass than a balloon. A golf ball is made of dense materials like rubber and hard plastic, while a balloon is filled with air or helium, which is lighter. The mass of an object is determined by the amount of matter it contains, so the solid material of a golf ball will generally have a higher mass than the gas inside a balloon.

Yellow candles typically burn the fastest because they contain chemicals that help accelerate the burning process.

Pepper water does not freeze faster than tap water. The freezing point of water is 0 degrees Celsius, regardless of whether it contains pepper or not. The presence of pepper may affect the appearance of the ice crystals that form as the water freezes, but it does not impact the rate of freezing.

In a controlled experiment, the independent variable is the factor that is intentionally changed or manipulated by the researcher. This is done to observe its effect on the dependent variable, which is the factor being measured or observed. Controlling all other variables except the independent variable allows for a clear understanding of the relationship between the two variables.

J. J. Thomson observed that cathod rays are deflected by an electric field - and from this discovered the electron.

Well... using milk would be a scientifc breakthrough, but not a single scientist has find a way to use milf as a fuel. So therefore, the only way for milk being use as a fuel is in the future. The reason why scientist migh have to try it is when the earth is completely out of oils which would happen sometime in the future. email:jasonmassey2011_4@hotmail.com

Ps the water has to be boiling

Ernest Rutherford's famous gold foil experiment, which led to the discovery of the atomic nucleus, was conducted at the University of Manchester in England in 1909.

A rubber ball would generally bounce higher than a golf ball or a ping pong ball due to its elasticity and ability to store and release energy upon impact. Ping pong balls, being lightweight and hollow, can also bounce quite high but may not have the same level of bounce as a rubber ball. Golf balls are designed for low bounce as they are meant to stay on the ground when hit.

Yes, a balloon that is half-filled with air and the other half with helium will float because helium is lighter than air. The helium will cause the overall density of the balloon to be lower than the surrounding air, resulting in it floating.

Rutherford concluded that an atom has a small, dense, positively charged nucleus surrounded by mostly empty space where electrons orbit. This model later became known as the planetary model of the atom.

Water can be used to dissolve cornstarch, but more details would be needed to know what this particular experiment uses.
