You are doing a lab in which you use hydrochloric acid. What kind of safety equipment should you wear?
I think it's wrong to be upset. I can see you being upset for people not wishing you happy birthday but seriously for an iphone? Do you not realise how much an iphone cost, not only that but you have to pay a monthly bill and smart phones are expensive on the bill because of the amount of data it uses. Your sister probably got decorations because she has been gone. But your parents will most likely NOT buy you an iphone because if its a birthday present, why do they want to pay $80+ just for you every month when your birthday is only once a year. You should ask for an ipod instead.
that's from the sun and there is not much that will remove it. We always just replaced them, because usually they were brittle too and no longer viable as a safety device. besides riding is the shield sit in the sun a lot ?
