Answer:
It has 3 sigma bonds
Explanation:
A sigma bond is a covalent interaction between two atoms, these bonds are the strongest type of covalent bonds and they are formed by the overlap of atomic orbitals.
The nitrogen is bond to the bromine atoms through sigma bonds, which means that exist 3 sigma bonds in the molecule.
this molecule has a trigonal pyramid geometry due to the free pair of nitrogen electrons.
Answer:
A pathway by which counter ions can flow between the half-cells without the solutions in the half-cell totally mixing.
Explanation:
Salt bridge is a link between oxidation half and reduction half of a galvanic cell.
Functions of salt bridge are:
Maintaining electrical neutrality
Preventing cell from reaching equilibrium
For creating salt bridge, a U shaped glass tube is filled with an inert electrolyte. Electrolytes used in the salt bridge generally do not reacts with the cell chemicals.
Cations and anions of the electrolytes have same ionic conductivity and hence, migrate with the same speed.
Most commonly potassium chloride, sodium chloride and potassium nitrate are used as an electrolyte in salt bridge.
Electrolyte are generally mixed with agar agar to prevent mixing of chemicals in the two half cells.
I think the answer is 2Mg + H2O4 = Cu12O4 + 2H
I’m really not sure though so it might be wrong… I’m not the best at balancing equations lol
Answer:1 grams Magnesium Hydroxide is equal to 0.017146870490373 mole.
Explanation:The molecular formula for Magnesium Hydroxide is Mg(OH)2. The SI base unit for amount of substance is the mole.
2mg(s)+02(g)=2mg0 that was the correct answer
