An electromagnet is a magnet that is created using an electric current -- created by electricity. Since electricity can be turned on and off, so can an electromagnet. It can even be weakened or strengthened by decreasing or increasing the current. Also when charges, like electrons or protons, are stationary, they produce electric forces. But when they're moving, they produce magnetic forces.

Well I'm sure many a time you've seen on some science experiment someone wrap a copper wire around a nail well thats generally the idea for electromagnets you get a solid piece of iron which is the only metal that is magnetic and you wrap a copper wire around it and the idea is to make two opposing magnetic poles by aligning the molecules with a electrical charge (a battery) so now with all three pieces assembles you have a copper wire attached to two sides of a battery and wrapped around a nail

Answer:

Methyl group

Explanation:

From the diagram shown, we can see that the family group CH3 is attached to the structure.

This is simply called a methyl group because it is derived from me than and written that way to show the direct bonding between carbon and the 3 hydrogen atoms.

The chemical formula for baking soda is NaHCO. Does baking soda contain metallic or non-metallic elements? Which one is which?

Fed [463]

Answer:

Both metals and non metals.

Explanation:

The correct formula of baking soda is NaHCO₃,

An element is considered to be metal if it is able to give electron easily due to very low ionization energy.

A non metal is ready to accept electron easily due to high electron affinity.

In sodium bicarbonate :

Na: Sodium : metal

H : Hydrogen: non metal (although placed with first group, alkali metals, in the periodic table as it readily loses electron like metals)

C: Carbon: Non metal

O : Oxygen : Non metal.

So the compound contains both metals and non metals.

An organic chemist measures the temperature T of a solution in a reaction flask. Here is the result. T = 149.206 °C Convert T to

jolli1 [7]

Answer: The temperature of the solution in Kelvins is 422.356 K

Explanation:

Temperature is defined as the measure of coldness or hotness of a body. It also determines the average kinetic energy of the particles in a body.

This term is expressed in degree Celsius, degree Fahrenheit and Kelvins. All these units are interchangeable.

The S.I unit of temperature is Kelvins.

We are given:

Temperature of a solution = $149.206^oC$

Conversion used to convert degree Celsius and Kelvins is:

$T(K)=[273.15+T(^oC)]$

$T(K)=273.15+149.206\\T(K)=422.356K$

Hence, the temperature of the solution in Kelvins is 422.356 K

Which type of reaction produces the most dangerous radioactive waste?

k0ka [10]

The correct answer to the question above is fussion of uranium. The fussion of uranium is the only type of reaction in which produces the most dangerous radioactive waste. The fusion of uranium means the binding of their atoms and produce a radioactive waste.
