1.)
chemical equilibrium is described as being dynamic because

the mass of the reactants changes to equal the mass of the products

the concentration of the reactants changes to equal the mass of the products

opposing reactions are constantly occurring at an equal rate

it cannot be changed
3 points

2.)
a reversible reaction at equilibrium can counteract the stress of an increase in pressure by

favoring the formation of more moles of gaseous products

favoring the formation of fewer moles of gaseous products

favoring the formation of more liquid products

favoring the formation of more solid products

Read "who built the pyramids? ”. leave this link open while you answer the questions throughout the assignment. give at least two reasons why some people claim the pyramids of giza were constructed by aliens.

Movement that is like a t a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. transfers energy from one location to another a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave
