Answer:
A. maintain electrical neutrality in the half-cells via migration of ions
Explanation:
Salt bridge -
For an electrochemical reaction , involving an anode and a cathode , both the electrodes are connect via a salt bridge to complete the circuit for the reaction .
One of the very important use of a salt bridge is to maintain the electrical neutrality of the respective half cells , which is achieved by the movement of ions .
Hence , from the given options , the correct option is ( a ) .
The energy required is Ionization energy
The answer is D because large hydrocarbons have a higher number of carbon which means an increase in boiling point and also rate of flow decreases, so they become solids.
Answer:
ch4 + 2o2 gives co2+2h2o +891kj
Explanation:
becoz 891kj heat energy is given out
exothermic process means heat energy is given out/ released
Answer:
The answer for number one is (a)
The answer for number 2 is (b)
Explanation:
#1. Mass/volume=density
#2. The solution is basic and a solute is sugar so in order for it to be basic you would have had to add the sugar to something acidic, and with the ratio of the solute to solution the acidity is 3.8
