Answer:
SF4 -Covalent bond
BaBr2 - Ionic bond
Ca - Metallic bond
Explanation:
Sulphur and fluorine are non metals. Nonmetal atoms combine by the sharing of electrons. This is also called a covalent combination(bond).
In BaBr2, a metal is combined with a nonmetal. This combination involves a transfer of electrons from the metal to the nonmetal forming an ion pair. This is otherwise called an ionic bond.
Atoms of a metal are held together by strong metallic bonds that involves positively charged cations and a cloud of electrons.
Answer:
Explanation:
The answers are all written in the attachment below. Pardon the writing
PE= weight x height. (remember weight is the force of gravity acting on objects...NOT the same as mass)
PE=3*2*9.8
PE=6*9.8
PE=58.8 J (for joules which is the unit for both Kinetic and potential energy)
Hope this helps :D
What kind of energy transfer
The correct response is C. Chlorine forms 1 covalent bond while Oxygen forms 2 covalent bonds.
