Answer:
if you drop a water balloon onto the ground, its kinetic energy is converted mostly to thermal energy. If the balloon weighs 1 kilogram and you drop it from about 2 meters, it will heat up by less.
Explanation:
As you say, kinetic energy of large objects can be converted into this thermal energy. For example, if you drop a water balloon onto the ground, its kinetic energy is converted mostly to thermal energy. If the balloon weighs 1 kilogram and you drop it from about 2 meters, it will heat up by less than.
Answer:
K^+(aq) + Br^-(aq) -----> KBr(aq)
Explanation:
The net ionic equation shows the actual reaction that occurs in the system. The molecular reaction equation includes the spectator ions but the net ionic equation does not include the spectator ions.
Spectator ions do not participate in the main reaction going on in the system.
Hence, for the reaction of potassium hydroxide and ammonium bromide, we have;
K^+(aq) + Br^-(aq) -----> KBr(aq)

There are 3 significant figures. Significant numbers are the numbers that build up your total number. 1-9 always count, 0 only counts if it’s after another number. For example: 0,901 has 3 significant numbers as does 0,910. 9,10 also has 3. 0,09 has just 1.
