Finding the formula of magnesium oxide Aims When magnesium is heated in air‚ it reacts with oxygen. During this oxidation reaction‚ magnesium oxide is produced. This increases the mass. If we know the mass of magnesium at the start‚ and the mass of magnesium oxide produced at the end‚ we can work out the mass of oxygen which has been combined with the magnesium. We can use these masses to work out the formula of magnesium oxide. Eye protection must be worn Apparatus Crucible and lid

What is Magnesium chloride(MgCl2)? What is it used for and why? What does it look like? Magnesium chloride is the name of a chemical formula of MG CL two. This is a salt and they are a typical ion halide. halides are very soluble to water. magnesium chloride is used for deicing on highways in sidewalks and also parking lots it is a good source of de-icing. The color that it appears is white or colorless crystalline solid. What is magnesium or what is chloride? whare are they located? You can find

Using the circuit below‚ calculate the anticipated voltage drops across each resistor and record them below. Rt = R1 + R2 + R3 = 150Ω + 2.2kΩ + 3.3kΩ = 5650 x 10^3= 5.65kΩ I = V/R = 10V/5.65kΩ = 0.001769 x 10^-3 = 1.77mA Voltmeter1= 1.77mA x 150Ω = 0.2655 x 10^-3= 265.5mV Voltmeter2= 1.77mA x 2.2kΩ
