Answer:

physical

The zinc (which was already silver) coated the penny. The NaOH dissolved the zinc. (that was what made the water murky) And small pieces of zinc adhered to the penny (coated) It was a physical change because no NEW color was created.

What are ionic bonds composed of?
Sonbull [250]

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.

true or false: ionic bonding involves the shareing of electrons, oxide ions have a 2+ charge , electrons have a negative charge
Elis [28]
Ionic bonding does not involve the sharing of electrons, that one is false. In ionic bonding, the metal's electrons are given to the non-metal, so that they're both like the nearest noble gas (full electron shells.) They are then drawn together because one has a negative charge (the non-metal) and one has a positive charge (the metal.)

Oxide ions have a 2+ charge: This is false, oxide ions have a 2- charge.

Electrons do have a negative charge, this is true.

Hydrogen molecule: pretty sure this is true. We know this because both atoms are non-metals.

The last one is true: a covalent bond is a shared pair of electrons between two atoms, however be aware that there can be more than one covalent bond between two molecules.

Calculate the mass of sodium acetate trihydrate required to make 100. ml of a 0.100 m solution. as part of your preparation for
vova2212 [387]

Required moles of CH₃COONa.3H₂O = Molarity x Volume of solution in L

                                                            = 0.100 M x (100.0 mL)

                                                            = 0.100 M x 0.100 L

                                                            = 0.01 mol

Required mass of CH₃COONa.3H₂O = Required moles x Molar mass

                                                            = 0.01 mol x (136.08 g / mol)                                                                              = 1.3608 g
