Jane has a weight of 500 N. The area of her two feet is 250 cm2. [2] The pressure when she is standing is Pressure = 500/250 = 2 N/cm2.

Jane wears stiletto heels. The area of one stiletto heel is 2 cm2.

Calculate the pressure on the floor when Jane puts all her weight on one heel. Show your working

Sulfuric acid is a polyprotic acid. write balanced chemical equations for the sequence of reactions that sulfuric acid can undergo when it's dissolved in water.

Astable electron arrangement for an atom is one that does not easily change. how is this arrangement arrived at? a. valence electrons are transferred or shared to create a full outer shell of electrons. b. valence electrons are discarded into space to create a full outer shell of electrons. c. protons (positive charge) pair with valence electrons (negative charge) to create a strong bond. d. outer shells with valence electrons are transferred or shared.

The polarity of an oxygen-hydrogen bond is higher than the polarity of a nitrogen-hydrogen bond, allowing amines to be more soluble than alcohols.
