way for seeds to sprout?

[NowhereMan]

Im new to growing, i got my seeds and i soaked them in water, some seeds sprouted but i still have a lot that haven't sprouted. How do i make sure they grow? should i use a heat mat? i atached a picture of how the seeds currently are.

dont wait on the rest
put them in soil let them start growing
if ya dont
they will die
.and some seeds will never germinate
they do,or they dont
peace
