What temperature of metal will burn human skin?
Metal can cause burns at temperatures as low as 50-60 degrees Celsius. Skin can suffer first-degree burns at this temperature, while more severe burns can occur at higher temperatures. It's essential to handle hot metal with caution and appropriate protective equipment to avoid burns.
What is the formula of the second compound if two oxides of a metal contain 27.6 percent and 30 percent of oxygen respectively and if the formula of the first compound is M3O4?
Formula of first oxide = M3O4 let mass of the metal be == x percentage of metal in M3O4 = (3x/ 3x+64) *100 but % age = (100-27.6) = 72.4 % so, (3x/ 3x+64)*100 = 72.4 or x = 56. in 2nd oxide, oxygen = 30%....so metal = 70% so, ratio :-- M : O 70/56 : 30/16 1.25 : 1.875 2 : 3 so, 2nd oxide = M2O3
