I have a min pin that is 3 months old, he has been sleeping a lot lately and I just noticed that his breath smells like blood is there something serious going on with him? Should I take him to the vet?

I am a little paranoid about being pregnant because my belly is getting bigger around my abdomen area and my breasts have been getting bigger but nothing else has, so my question is can you be pregnant if you are bleeding?

Fiance is filing taxes but he is in the last part of his divorce. She doesn't work but she has the child. The child is disabled, he doesn't live at home so he pays for both households. Can he file "HEAD OF HOUSEHOLD" or "SINGLE" or does he have to file "MARRIED BUT SEPARATE" even though he pays for everything including her living expenses

My fiance and are are arguing over who's family pays for what at the wedding. What does the Grooms parents pay for? What does the Brides parents pay for?

any help with this is life saving please explain the answer I don't want just the answer how does this conversion work??? THANKS IN ADVANCE FOR YOUR HELP!!!!!!!!!!!!!!!!!!!!

A. 1.76x10^-3 mol of Cesium

B. 0.0125 mol of Neon

C. 5.29 x10^3 mol of Lead

D. 0.00000122 mol of Sodium

E. 5.51 millimol of Arsenic

F. 8.72 mol of Carbon

ok here is the problem and as I look through my book I'm not really sure that any of it helps me understand what this is saying:

"Ammonium nitrate is a high explosive if not handled carefully, breaking down into nitrogen gas, oxygen gas, and water vapor. The expansion of the three gases produced yields the explosive force in this case. Write the unbalanced chemical equation for this process"

Please help me if you can I don't understand how to start or finish this I missed this day in class so i'm tryin to catch up please explain...

Thank you
