The graph line that doesn't change in amounts.
Explanation:
Meaning if its a straight line horizontally across it is in equilibrium. If you don't know what I mean, search up equilibrium graph, and it will show you what I am talking about.
Answer:
A. Brahe and Kepler
Explanation:
The Copernican model was a heliocentric model of the universe. Copernicus thought that the Sun is stationary, and the Earth and the other planets are orbiting around it. He also noted that the stars are further away from the Sun compared to the distance between the Earth and the Sun. Three very important hings in his theory are that he thought that the Earth rotates around its own axis, revolves around the Sun, and has annual tilting of its axis. At some things, Copernicus was right with his theory, at some he wasn't, but anyway he made one giant step forward in the understanding of the universe. His theory was supported by many, though mostly after his death, with one of the most noticeable supporters of him being Ticho Brache and Kepler who made model of his theory, as well as improving it.
Explanation:
Covalent bonds:
- They are bonds that are formed by atoms that shares their valence electrons.
- They are formed by atoms with very low electronegativity difference.
- It is usually a bond between non-metals.
Covalent bonds are bonds formed when two atoms jointly shared their valence electrons in order to form a bond.
For the formation of this bond type, each of the atom requires odd or unpaired electrons.
To form a covalent bond, each of the two participating atoms would put down an unpaired electron to be used in forming a shared pair of electrons between them.
