Which component is reduced during the electrolysis of brine?
water
What will happen to water molecule when electricity is passed through water during electrolysis?
when electricity is passed through water using electrolysis, it will decompose to form hydrogen (H2) and oxygen (O2) atoms
What is the relationship of volume of water to its mass?
volume in litres is equal to its weight in kgs 1000ltrs is equal to 1000kgs
Can a chemical reaction occur during the electrolysis of water?
yes. hydrogen and oxygen gas will be evolved
Is a body totally submerged in a liquid displaces a volume of water less than its volume?
A body which is totally submerged in a liquid displaces a volume of water equal to the volume of the body.
During water electrolysis does the water have to be warm?
No
Which component is reduced during the electrolysis of brine?
water
When body is immersed in water then water equal to the volume explain this?
The water displaced by the body is equal to its volume.
What is equal to the volume of water an object displaces?
volume of water an object displaces is equal to the volume of the part of the object inside it
What will happen to water molecule when electricity is passed through water during electrolysis?
when electricity is passed through water using electrolysis, it will decompose to form hydrogen (H2) and oxygen (O2) atoms
Why does using sodium bicarbonate as electrolyte when performing electrolysis of water produce less than one half volume oxygen for every one volume of hydrogen produced?
Because the electrolysis of water reaction always produces twice as much hydrogen (by volume or by mole) as they do oxygen. H2O(l) -> H2(g) + 1/2 O2(g)
What is the relationship of volume of water to its mass?
volume in litres is equal to its weight in kgs 1000ltrs is equal to 1000kgs
How do you use submerging method to calculate volume?
The volume of water displaced is equal to the volume of the object submerged into the water
How do you we measure the volume of an irregular shaped solid object?
Immerse it in water and its volume is equal to the volume of water displaced
How can an irregular volume be measured?
By placing the object in water and the volume of water displaced is equal to the volume of the object immersed
Can a chemical reaction occur during the electrolysis of water?
yes. hydrogen and oxygen gas will be evolved
How does the amount of buoyant force exerted by water vary with the volume of submerged solid?
The amount of buoyant force is equal to the weight of the displaced water. The VOLUME of the displaced water is equal to the part of the solid that is submerged - thus, the buoyant force is equal to this volume, times the density of the water.
