Answer:
True.
Explanation:
An exothermic reaction has a positive enthalpy (heat) of reaction. However, it can be negative in some circumstances.
The general form would be
Reactants ---> Products
Answer:
quantum mechanical model: A model of the atom that derives from the Schrödinger wave equation and deals with probabilities. wave function: Give only the probability of finding an electron at a given point around the nucleus. The quantum mechanical model of the atom also uses complex shapes of orbitals (sometimes called electron clouds), volumes of space in which there is likely to be an electron. So, this model is based on probability rather than certainty.
The heat in particles travels through convection at a certain speed depending on what density a mass has.
Answer:
Transition elements are elements which have partially filled d-orbitals and form at least one or more stable ions.
