Is anyone just falling apart? I have a friend who I love so much and shes angry with me for good reason. A friend that is like a brother to me and hes going into the Marines and I'm terrified bc my grandpa died in the Marines and I can't lose my bsf. My other bsf is busy and can't talk rn. I'm literally having an anxiety attack and id k what to do. I just want to give up but ik I can't. If you 3 are seeing this (not including my fam but i love you guys too lol) I love you guys so much, you dont even know.

What happened in 2012 and how does it illustrate the importance of understanding the sun and how it works?

Astudent is given a sample of a blue copper sulfate hydrate. he weighs the sample in a dry covered porcelain crucible and got a mass of 23.875 g for the crucible, lid, and sample. the mass of the empty crucible and lid was found earlier to be 22.652 g. he then heats the crucible to expel the water of hydration, keeping the crucible at red heat for 10 minutes with the lid slightly ajar. on colling, he finds the mass of crucible, lid, and contents to be 23.403 g. the sample was changed in the process to very light clue anhydrous cuso4. if there are again 100.0 g of hydrate, how many grams of cuso4 are in it? how many moles of cuso4? (hint: molar mass of cuso4 = 159.6 g / mole. what per cent of the hydrate is cuso4? you may convert the mass of cuso4 to moles.)

Iron (3) oxide will decompose in the presence of hydrogen gas and heater to produced iron and digydrogen monoxide white a balanced chemical equation
