The products that would be formed if chlorine gas was bubbled <span>through a solution of sodium bromide would be sodium chloride and bromine gas. The reaction would be written as:
2NaBr + Cl2 = 2NaCl + Br2</span>
Answer:
Valence electrons are the outermost electrons of an atom and are normally the only electrons that participate in chemical bonding. Atoms with full valence electron shells are extremely stable and therefore do not tend to form chemical bonds and have little tendency to gain or lose electrons.
Answer:
yes....
Explanation:
Let me explain the molecular orbital diagram of N2 using its diagram.
one atom of nitrogen has 7 electrons so a N2 molecule will have 14 electrons
so first 2 electrons go in 1s sigma bond
next 2 in 1s sigma anti bond orbital
next 2 in 2s sigma bond orbital
next 2 in 2s sigma anti bond orbital
next 2 in 2pz sigma bond( assuming that z axis is the internuclear axis ) orbital
Why are open systems inappropriate for studying the conservation of mass?? The sample may become contaminated. Matter may be created or destroyed within the system. Heat can escape from or enter the system. Matter may be lost to or gained from the surroundings.
