Hydrochloric acid and sodium hydroxide react to produce water and sodium chloride in an endothermic reaction. Which
statement must be true of the reaction? (1 point)

More bond energy is absorbed on the reactants
side than is released on the products side.

The bond energy used to break the bonds in
hydrochloric acid and sodium hydroxide is less
than the energy released to form the bonds in
water and sodium chloride.

The energy of each bond in water and sodium
chloride is greater than the energy of each bond in
hydrochloric acid and sodium hydroxide.

The total bond energy of water and sodium
chloride is greater than the total bond energy of
hydrochloric acid and sodium hydroxide.

You and a friend (alex) are at a a tree-top adventure park .. . part of the course requires you to climb up a rope. you both climb the same rope in the same amount of time. however, the tension in the rope is greater when alex climbs. who did the most work? alex did - more tension means more force - more force means more work was done you did - less tension means less force - less force means more work was done to find the work done, the force exerted and distance moved are multiplied. a couch is moved twice before you are happy with its placement. the same force was used to move the couch both times. if more work is done the first time it is moved, what do you know about the distance it was moved? when more work was done, the couch was moved less. when more work was done, the couch was moved further. when more work was done, the couch wasn't moved at all. when more work was done, the couch was moved the same distance.

The seven sisters, seven stars located more than 400 light-years away in the taurus constellation can be seen here with venus and another constellation, orion. the seven stars stay grouped together but seem to move, like the planet venus. why do stars seem to move like planets in the night sky?
