Reactions of metals with acids producing salts
Measure 50 cm 3 of dilute sulfuric acid using a measuring cylinder and pour it into the beaker. Warm this acid gently over a low, non-smokey, Bunsen flame. Turn off the Bunsen burner before the solution boils. Carefully remove the beaker of acid from the tripod as instructed by your teacher, and stand it on the heat resistant mat.

Overspændingsbeskyttere vs strømafbrydere: Hvad er forskellen?
A afbryder er en automatisk betjent strømbeskyttelsesafbryder, der bruges til at beskytte et elektrisk kredsløb mod skader forårsaget af overbelastning eller kortslutning. Den overvåger strømstrømmen og afbryder automatisk kredsløbet, når den registrerer, at strømmen overstiger en sikker tærskel. Hovedformålet med en afbryder er at forhindre overophedning af …
