Answer:
Explanation:
Earthquakes are normally caused by underground rock breaking along a fault line. The seismic waves that cause the earth to shake are caused by this sudden release of energy. The plates or blocks of rock begin to move during and after the earthquake, and they continue to move until they become trapped again. As fluid near the center heats up, convection currents develop within the Earth's mantle. Particles pass more quickly as the core heats the bottom layer of mantle material, lowering its density and allowing it to rise. The convection current is started by the growing material.
Fats , oils , waxes and sterols are collectively known as lipidsand the true fats contain only carbon , hydrogen and oxygen
I'm not sure but I think it is A. image one has the most spread out particles like a gas, and b has closer together particles like a liquid or solid. since there are no choices that say A=gass and B=solid, so I am guessing it is answer A.
Answer:
A
Explanation:
matter has mass and undergoes a phase change
Answer:
because the product of CuO contains 2 molecules so it is unbalanced
Explanation:
to balance it 2Cu+2O=4CuO now it is balanced
