Pythagoras was the first ancient astronomer to suggest that there was a harmony of the spheres, and that the movement of the planets, sun, moon and stars could be described by whole numbers and mathematical precision. His other discovery was that the morning and evening star are the same thing, the planet Venus.
Explanation:
if im right plz give me brainliest !! :)
Mass/moles x mr
so you need to work out the rfm of Ca(OH)2= 40(16+1)2= 40+34= 74
and then use the formula= moles x mr
6.25 x 74= 462.5
Answer= 462.5g
Answer:
Hot material near the core is less dense and rises, when it cools, it becomes more dense and sinks.
Explanation:
This best explains how heat plays a role in the movement of materials within Earth's interior because it's how convection works. Convection is the circular motion that happens when warmer air or liquid which has faster moving molecules, making it less dense rises, while the cooler air or liquid drops down. Convection currents within the earth move layers of magma, and convection in the ocean creates currents.
You forgot one...and that happens to be the answer---> Accuracy
