Answer:
False
Explanation:
They’re used cause they’re generally harder than pure metals
I think it's 231/90 Th
Whatever the decomposition equation yields ( X + He) needs to add up to the reactant (U)
Cr(NO3)3
because Chromium (III) formula is Cr2O3 And Nitrate formula is NO3
The answer is E. You must use the formula q=mCDeltaT to solve this equation. You must also use the formula that q(reaction)=q(solution) to solve this problem
I would honestly say C. All others have ingredients in them that makes them work, the combination of stuff to put out the fire, film is made from a certain material and drugs are an ovbious mixture. Looking at the stars is the only thing you don't need chemistry for.
