 okay so this one says write the balance equation showing all states which represents the complete dehydration of the compound magnesium sulfate have the have to hydrate so magnesium sulfate have to hydrate it looks like that they say it's a solid and they want to show the complete dehydration reaction to here on the video so in order to show the complete dehydration remember we're going to keep this thing shut and show the equation so MGS04 solid that's what's left that's the remnants of what's left so that's the first step to doing these grab a metric analysis problems you're gonna be on the video so remember you're gonna have to figure out those reaction equations first we'll continue along with this one next
