Ca(s) + 2 H2O(l) Ca(OH)2(aq) + H2(g)

Question

acid-base
double-displacement
gas evolution
oxidation-reduction
precipitation
single-displacement
synthesis

whichs one(s) is it??

thanks

Answer 1

gas evolution

Answer 2

Also a redox reaction.

Answer 3

its not also a precipitation os single-displacement??

Answer 4

or acid- base? because i did gas evolution
oxidation-reduction
precipitation
single-displacement

but got it wrong so I am thinking either one of those has to be taken out and/or acid-base added

Answer 5

Depending upon how much Ca reacted, it could be pptn since Ca(OH)2 is not all that soluble.
And it can be single replacement. You are replacing H with Ca.

Answer 6

could it also be an acid-base?

Answer 7

I got it:) it was just not a precipitate:)

Thankyou sooooo much:)

Answer 8

If you use the right definition, yes it can be an acid/base reaction.
