Image result for What happens to sodium chloride when it dissolves in water
Explanation: On addition to water the Na+ section of NaCl is attracted to the oxygen side of the water molecules, while the Cl- side is attracted to the hydrogens' side of the water molecule. This causes the sodium chloride to split in water, and the NaCl dissolves into separate Na+ and Cl- atoms
Answer:
in physics we never work with minutes only seconds.
The red diamond tells how flammable the chemical compound is or how easily it catches fire.
The yellow diamond tells about reactivity how quickly the compound reacts with other materials.
Answer:
HBr + Mg(OH)2 —> MgBr2 + H2O.
To balance the above, we must do a head count of the individual atoms present to ensure they balance on both sides of the equation. To get the balance equation, add 2 in front of HBr and 2 in front of H2O as shown below:
2HBr + Mg(OH)2 —> MgBr2 + 2H2O
We can see clearly that the numbers of the individual atoms on the left side is the same on the right side
