Answer:
When a substance is heated, it gains thermal energy. Therefore, its particles move faster and its temperature rises. When a substance is cooled, it loses thermal energy, which causes its particles to move more slowly and its temperature to drop.
1. New moon, waxing gibbous, Full moon, and waning crescent are the main ones but there are more.
2. The revolution of the Earth is 365.25 days while the revolution of the moon is 28 days. Also, the Earth orbits the sun while the moon orbits the Earth and vaguely orbits the sun due to the orbit of the Earth.
3. Tidal waves, seasons, and the lunar cycle.
4. Moonlight is light that is reflected off the moon's surface that comes from the sun. This "lights" the moon up. Sunlight is light that comes from the sun which is made by a bunch of chemical reactions.
Good luck!
Zn+2HCl ----> 2ZnCl2 + H2
For 2.50 g of Zn
Mass per mol = 2.50/molar mass of Zn = 2.50/65.38 = 0.0382 g/mol
There are two moles of ZnCl2 and total mass = 2*0.0382*molar mass of ZnCl2 = 2*0.0382*136.286 = 10.42 g
For 2 g of HCl
Mass per mol = 2/2*molar mass of HCl = 2/ (2*36.46) = 0.0274 g/mol
For the two moles of ZnCl2, mass produced = 2*0.0274*136.286 = 7.48 g
It can be noted that 2 g of HCl produced less amount of ZnCl and thus it is the limiting reagent.
Answer:
Answer :-
Explanation:
Heat is the total energy of the motion of the molecules of a substance, whereas the temperature refers to the measure of the average energy of the motions of the molecules in the substance.

Answer:well it should stay the same since nothing was taken away or
Moved. When it comes to liquids, only the property of shape can change unless you physically take away or add some.
