Soldering guns often use a soft solder alloy composed of 35.5% lead. If you are soldering parts onto a wagon and are only allowed to have a maximum of 2.51 g of lead in the finished product, how much solder can you use to attach all of the parts?

7.07g of solder

Explanation: This can be represented by the equation 2.51 = 0.355x with x being the grams of solder. To solve this we divide by 0.355. 2.51/0.355 = 7.07 (three sig figs).

answer: you could do some invislibe ink.

explanation: i will tell you how to if u answer my question.

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
