Answer 2

Answer:

A chemical reaction can be expressed as an equation. A chemical equation shows the chemicals that react (the reactants) followed by an arrow followed by the chemicals that are produced by the reaction (the products). Here is an example of a chemical equation: Al + O2 --> Al2O3.Mole Ratios

Aluminum reacts with oxygen to produce aluminum oxide as follows: 4Al + 3O2 → 2Al2O3 a.Answer. 1g of oxygen will react with 1 g of calcium and form calcium oxide. 2Ca+O 2 = 2CaO.Aluminium does not burn. ... Aluminium powder burns, and possibly extremely thin foil. But so does iron powder; that's why you see sparks coming off a grinding wheel. In fact, most metals, except for the noble ones, burn when exposed to conditions that are oxidizing enough, and with a high enough surface-to-volume ratio.sodium reacts with oxygen producing a lot of heat and light after the reaction is over, sodium oxide will be left. sodium(S) + Oxygen (O2) --> Sodium oxide (Na2O)It is present in the environment combined with other elements such as oxygen, silicon, and fluorine. Exposure to aluminum is usually not harmful, but exposure to high levels can cause serious health problems. If you think you have been exposed to high levels of aluminum
