Electromagnet - the strong magnetic field produced inside a solenoid can be used to magnetize a piece of magnetic material like soft iron when placed inside the coil. the magnet so formed is called electromagnet. the magnetic effect remains only till the current is flowing through the solenoid.
Uses of electromagnetelectromagnet is used in electric bells
electromagnet is used in electric motors electromagnet is used in telephone diagrams
electromagnet is used in for sorting scrap metals

What is the sum of the coefficients of the balanced equation for:
Pb(NO3)2 + Al2(SO4)3 ----> Pb2SO4 + Al(NO3)3
Answer:
3 Pb(NO3)2 + Al2(SO4)3 = 2 Al(NO3)3 + 3 PbSO4
Explanation:
I think your equation is incorrect? This is balanced and the sum of coefficients is 9.
Balance the equation by putting the correct number in front of each compound. You can work this out mathematically or by drawing pictures on a piece of paper like the videos.

what statement best describes a mole
a- it is use mainly for writing chemical formulas
b- it is used for chemical equations that have reversible reactions
c- it is used for direct comparing the amounts of substances
d- it is used mainly for dealing with fluid substances
Moles are the unit of measurement that estimates the amount of the substance in a sample. It directly compares the amounts of substances. Thus, option c is correct.
What are moles?Moles are said to be the SI unit to estimate the number of substances like atoms, molecules, ions, etc., in a sample. It is used to measure the elementary entities that are small in size.
It is abbreviated as mol and is equivalent to 6.02214076 × 10²³ particles (Avogadro number). It can be calculated by mass and the molar mass of the substance and is shown as,
Moles (n) = mass ÷ molar mass
Where mass is given in grams and molar mass in grams/ mol.
The moles are used to estimate the molarity and are also used in the ideal gas equation. The moles will be more in the substance with less molar mass and vice versa.
Therefore, option c. moles directly compares the amounts of substances.

Answer:
62.15 m (squared)
Explanation:
We know that the Area of the square is 5.5 x 4= 22
so 90 degree to 30 degree is divide by 3
so u divide 22 by 3 and get 7.3 wich is the semi circle thing
now 7.3 x 5.5 = 40.15
22 + 40.15 = 62.15 m (squared)

Which of the following best explains what happens when salt dissolves in water?
Answer:
The answer Is the polar solvent molecule surrounds the positive sodium ions and the negative chloride ions.
The highly polar molecule covers the positive ions of sodium as well as the negatives chloride ions whenever salt dissolves in water.
What is solubility?The ability of a material, the solute, to combine with that other substance, the solvent, is known as solubility in chemistry. Insolubility, or the solute's inability to create such a solution, is the opposite attribute. The concentration of both the solute inside a saturated solution—a solution whereby no more solute could be dissolved—is typically used to gauge the degree of a substance's solubility in a particular solvent.
For some solutes as well as solvents, there might not be any such limit, in whose case these two substances are referred to as "miscible in any quantities". The highly polar molecule covers the positive ions of sodium as well as the negatives chloride ions whenever salt dissolves in water.
Therefore, the highly polar molecule covers the positive ions of sodium as well as the negatives chloride ions whenever salt dissolves in water.
