How many grams of copper does it take to kill you?
10 grams of copper can kill you. But copper sulphate won't kill you. So don't freak out!
How many pennies does it take a copper bar?
You need to know 2 things - what is the weight of the copper bar, and what are the dates on the pennies?The reason you need to know the dates is that pennies have very different amounts of copper in them depending on when they were made. Lincoln cents from 1909 till 1942, and from 1944 to the middle of 1982 were made of 95% copper and weighed 3.11 grams, so each one has 2.955 gm of copper in it. But pennies made from the middle of 1982 to the present are mostly zinc - they weigh 2.5 gm and are 2.5% copper, so the only contain 0.0625 gm of copper apiece.That means if you have modern (1983 and later) pennies, you'd need A LOT of them. Say the bar weighs 500 gm. You'd need 500 / 0.0625 = 8000 pennies ... plus you'd have to melt them down and separate the zinc from the copper first!
How many minutes does it take for water to get 80 degrees F?
It depends entirely on what the initial temperature and volume of the water is and how much heat is applied.
How many new pennies make a pound of copper?
One modern cent weighs 2.5 grams and contains 2.5% copper, which is 0.0625 grams or about 0.000138 lbs of copper per penny. To get one full pound of copper, it would take 7,246 pennies.

Average time to melt milk chocolate?
It varies based on how you melt it and how much chocolate you are melting with what heat amount. In the microwave, it will take 2 to 3 minutes (stirring at 30 second intervals). In a double-boiler method over medium-high heat, it should take 5 to 10 minutes.

How long does it take to melt pure silica?
It takes about 3,100 degrees feirenheit to melt pure silica Pure silica (SiO2) has a "glass melting point"- at a viscosity of 10 Pa·s (100 P)- of over 2300 °C (4200 °F). The amount of time it would take to melt would depend on how much heat you applied.
