i hope so

can i ask u where do u live???

 

[L-Girl]

i hope not!

hey do u know why when salt is added to water, rust occurs faster?

 

[L-Girl]

can i ask u where do u live???

yes u can

 

[IGCSE O/L student]

paper 6 is harder

down goes the gt!

 

[white rose]

yes u can

so tel me....

 

[L-Girl]

so tel me....

egypt and u

 

[white rose]

egypt and u

hey do u know why when salt is added to water, rust occurs faster?

i wrote the stupidest answer ever: salt contains hydroxide ions and so contributes to rusting because rust is hydrated iron

hey do u know why when salt is added to water, rust occurs faster?

it is because salt is an impurity and rusting get speeded up because of impurity that is what our teacher told us

i told you my answer was wrng

 

[L-Girl]

i wrote that it would help water to conduct better :s better conductivity :S

i rote....bcoz salt is ionic cmpnd & so contibute to da rusting.....sm wht i dat

The right answer is that the water will contain ions which speeds up the rusting process

I wrote there will be more electrons...can it be okk??

water???
they said salt!
how do you know that's the right answer!

 

[L-Girl]

The right answer is that the water will contain ions which speeds up the rusting process

what about my answer?

 

[white rose]

The right answer is that the water will contain ions which speeds up the rusting process

yeah i meant da same

 

[Mohamed123456789]

I wrote there will be more electrons...can it be okk??

There will be no more electrons u r just adding ions

 

[svenas]

water???
they said salt!
how do you know that's the right answer!

I wrote there will be more electrons..but I don't think it ok

 

[L-Girl]

I wrote there will be more electrons..but I don't think it ok

who knows! it might be correct
