Chemistry! please help i mean really!?

when atom has positive charge, means lost electrons, has empty spaces bond other electrons. (h+, example, hydrogen no electron) number in front of + relative how many electrons lost. mg 2+ lost 2 electrons.
find total positive charge, have figure out how draw atom (lewis structure works best this). if have spaces no electrons, have positive charge. if have non binding electrons, have negative charge.
a, magnesium chloride, , because bonds 2 cl- (ions) neutral, has no charge.
magnesium sulfate bonds sulfate (sulfur , 4 oxygen) negative molecule (2-), again, molecule neutral.
try , figure out last 1 on own!
luck

if magnesium ion has charge of 2+ (mg^2+), total positive charge represented 1 formula unit of each of compounds:
a. mgcl^2
b. mgsov4
c. mgv2(pov4)v2

Is there such thing called a winged spider?

-
of all's answers comical, least. however, have clarify things amateur biologists, here. arachnids classified such having 2 segments bodies, not number of legs.solpugids arachnids, yet have ten legs, , no venom. solpugids include such animals "sun spiders" , "camel spiders" (which massive, , qualify writers call "nightmare fuel"... trust me... few tours in iraq, have seen several of these things). insects have 3 segments bodies. insects have 4 legs... 6-legged flying instects have 8 (yep... wings count "legs") or 10, depending on number of wings. pic in question, photoshopped, sure. no species of arachnid has wings. , if closely, hymenoptera wings.... bee wings, actually. if recall opening monologue "bee movie" (shut up... have kids), you'd recall line says "wings small, , wrong shape", or words effect. if bee can barely manage flight, spider similar wings wouldn't able waft own farts (if spider digestive...
