Why H2O is polar and CO2 is nonpolar? Both CO2 and H2O have two polar bonds. However the dipoles in the linear CO2 molecule cancel each other out, meaning that the CO2 molecule is non-polar. The polar bonds in the bent H2O molecule result in a net dipole moment, so H2O is polar. Which is […]
Which describes how a simple machine can make work easier?
Which describes how a simple machine can make work easier? Explain how a machine makes work easier. Machines make work easier by increasing the amount of force that is applied, increasing the distance over which the force is applied, or changing the direction in which the force is applied. What are three ways machines make […]

While we cannot stop global warming overnight, or even over the next several decades, we can slow the rate and limit the amount of global warming by reducing human emissions of heat-trapping gases and soot (“black carbon”). How you can stop global warming? How Can We […]
What are the general types of intermolecular forces?
What are the general types of intermolecular forces? The three major types of intermolecular interactions are dipole–dipole interactions, London dispersion forces (these two are often referred to collectively as van der Waals forces), and hydrogen bonds. What are the properties of matter influenced by intermolecular forces? As the intermolecular attraction increases, • The vapor pressure […]

Why do merry go round turn counter clockwise?
Why do merry go round turn counter clockwise? Traditionally, horses are mounted from the left side. This is because most warriors were right handed and kept their swords on their left side for fast access. In England, the carousels rotate clockwise so the horses can be mounted from the left, keeping with tradition. Why do […]
