Some single displacement reactions involve one halogen replacing a less reactive halogen.
Cl2, replaces iodine in Nal, producing I2and NaCl. Write the balanced single displacement reaction with the simplest
whole number coefficients.
• Do not include the states of the reactants or products.

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

answer: option (a) is the correct answer.

explanation:

the measurement of hydrogen ions in a solution is known as ph.

if ph of a solution is less than 7 then the solution is acidic. if ph of a solution is greater than 7 then the solution is basic.

when the ph of a solution equals 7, then the solution is considered as neutral.

the ph of pure water is 7, therefore, it means that concentration of hydronium ions equals that of hydroxide ions.
