Sorry if I'm wrong but it's 1) learner engages in scientifically oriented questions. 2) learner gives priority to evidence in responding to questions. 3) learners formulate explanations from evidence. 4) learner connects explanations to scientific knowledge. 5) learner communicates explanations.
A pendulum. Hold it high and it has potential energy but no kinetic energy because it is still. As it moves down when you drop it, it changes to kinetic energy and moves faster and faster until it's at the bottom where it has no potential energy. However, it still has momentum, so now it is changed to potential energy as it moves up the other side
The metal compound in period 3 is a group 1 metal - Na.
the compound is Na2O, the base annyhdride of NaOH :)
Answer:Ionic compounds are compounds composed of ions, charged particles that form when an atom (or group of atoms) gains or loses electrons. (A cation is a positively charged ion; an anion is a negatively charged ion.) Covalent or molecular compounds form when elements share electrons in a covalent bond to form molecules.
Answer: 
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
The balanced chemical equation for showing hydrogen peroxide decomposing into hydrogen and oxygen is:
