Answer asap with at least 3 or more sentences!

Answer:

no.

Explanation:

The reason this has

never happened is due to the source of magnetic fields: moving electric

charges. When electric charges (e.g. electrons) move in circles, they

produce a magnetic field. In a piece of iron, it is very easy to line up

these circles, getting all the little magnets to work together as one big

magnet.

For each of these circles, one side is the north pole and one side is the

south pole. Since each circle has two sides, each circle has a north and a

south pole. Even the smallest possible magnets (spinning electrons) have a

north and a south pole.

A reaction produces 0.883 moles of H₂O. How many molecules are produced?

prisoha [69]

The answer is 5.32 × 10²³ molecules

Avogadro's number is the number of units (atoms, molecules) in 1 mole of substance:
6.023 × 10²³ units per 1 mole

We have 0.883 moles.
If 1 mole has 6.023 × 10²³ molecules, 0.883 moles will have x molecules:
1 mole : 6.023 × 10²³ molecules = 0.883 moles : x

x = 6.023 × 10²³ molecules * 0.883 moles : 1 mole = 5.32 × 10²³ molecules

goblinko [34]

The balanced equation for

Ca(OH)2 + H3PO4→ Ca3(PO4)2 + H2O is

3 Ca(OH)2 +2 H3PO4→ Ca3(Po4)2 + 6 H2O

3 moles of Ca(OH)2 reacted with 2 moles of H3PO4 to form 1 mole of Ca3(PO4)2 and 6 moles of H2O

What term describes a carbon atom that has four different groups bonded to it?

oee [108]

A carbon which is attached to four different atoms or group of atoms with different environment is called as Chiral Carbon or Asymmetric Carbon.

Non-superimposable:
 The mirror image (molecule) of chiral carbon cotaining compounds are Non.Superimposable on each other. They are called enantiomers of each other.

Polarized Light and Chiral Carbon:
When a polarized light is allowed to fall on either enantiomer of chiral compound, it is rotated other clockwise or anti-clockwise.

Examples:
Below are three axamples of compounds containing chiral carbon.
