Molecules are made up by chemically bonding two or more atoms of the same element or different elements, they don’t have charge, and the atoms are bonded by covalent bonds. <span>Lattices have a three- dimensional ordered arrangement of basic units (that can be an atom, molecule or an ion). Lattices are crystalline structures with these repeated basic units. When ions joined with ionic bonds, they form ionic crystals. The formula unit tells us that aluminium hydroxide has a crystal structure made from molecules. </span>
Answer: inference because she drew a conclusion based on evidence.
why?:
Because the evidence was that she heard the crashing sound, and then when she came into her room saw the broken window and baseball.

The shape that is formed by the free surface, which is called a hyperboloid, or "Gabriel's Horn". The core of a vortex in air is sometimes visible because a plume of water vapor that is caused by condensation in the low pressure and low temperature of the core. An example of this is the sprout of a tornado. Vortices form in stirred fluids and could be observed in phenomena such as smoke rings, whirlpools in the wake of a boat, or the winds surrounding a tornado or dust devil.
I think it is true because that seems like the right answer
