"well, in the compound, it has 27.765grams, of which the metal is (27.765-2.809) grams, and the Br is 2.809 grams. " i dont understand this as you said br is 2.809 but the question says the unknown element is 2.809 grams?

**chemistry - ASAP**

An unknown element reacts with bromine to give bromide, MBr3. If 2.809g of the unknown element gives 27.765grams of MBr3, what is the element? ( give the symbol ) I dont understand the M in the MBr3...can someoen please help me with this question ASAP thanks a lot

and the other question is km/h the units i mean so the question is in an 8.00km race, one runner runs at a steady 11.8km/h and another runs at 14.5km/h .How far from the finish line is the slower runner when the faster runner finishes the race?

figure out its derivative so it will be chain rule so its 2(x^2+5x+2)^1(2x + 5) << this is the derivative of the inside and when u have this just sub in 5 so its 2(25+25+2)(10+5) = 1560
