What is calcium hydroxide equals calcium oxide+water in symbols

Ca(OH)2> CaO +H2O

Ca(OH)2CaO + H2O

Explanation:

looking at the equation it is balanced so this is the right equation for the reaction

you probably might be wondering how I got their compound formula right?

well its simple

for calcium hydroxide you have

calcium Ca^2+

hydroxide OH^- note those charges are their valency

so the valencies cross to be a sub scripts

so we have

Ca(OH)2

same is applicable to others

that's all

chemical energy --> gravitational potential energy --> kinetic energy --> elastic potential energy --> gravitational potential energy

explanation:

when emma starts the hike, the chemical energy stored in her body is used to climb up the mountain, and so she gains gravitational potential energy (because at the end, she will be at a higher height h above the ground). then she goes bungee jumping: as she falls, this gravitational potential energy is converted into kinetic energy (because her speed increases as she falls down), until the point when the rope stretches, and she stops moving. at that moment, all the kinetic energy is converted into elastic potential energy due to the stretching of the rope. then, this energy is released because the rope returns to its natural length, and emma gains a small increase in altitude , so she gains some gravitational potential energy.
