The answer is: (1) Cl2(g) + 2NaBr(aq)-->Br2(l) + 2NaCl(aq).
In this chemical reaction chlorine change oxidation number from 0 to -1 (reduction) and bromine change oxidation number from -1 to 0 (oxidation).
Chlorine is stronger oxidation reagent than bromine.
In VIIA or group 17 (halogen elements) there are six elements: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At) and tennessin(Ts).
They have high electronegativity because they have seven valence electrons in their outermost energy level, so they can gain an electron to have the octet rule.
Going down in the group, element are weaker oxidazing reagent and less reactive.
Electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.
The right answer is
Table A Organic solvent
No Perfume No Fuel No Anesthetic No Adhesive Yes
The answer is C. there are two potassium ions for each ion of sulfur
Answer:
All matter contains heat energy. Heat energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases. Heat energy can be transferred from one object to another. The transfer or flow due to the difference in temperature between the two objects is called heat.
