Answer:

The correct reaction is as follows:

2Mg + O2 → 2MgO

3. Synthesis

Explanation:

Chemical reactions are of different types depending on how they occur. One of these types is called SYNTHESIS OR COMBINATION REACTION. A synthesis reaction is that reaction in which two atoms of two elements are chemically combined to form a single molecule or compound. That is;

A + B → AB.

This is the case in this question where atoms of Magnesium (Mg) and oxygen (O) reacted to form a single compound of Magnesium oxide (MgO). Hence, it is said to be a SYNTHESIS REACTION.

How many grams are in 32.2 L of CO2?
Naddika [18.5K]

Answer:

63.25 grams of CO₂

Explanation:

To convert from liters to grams, we first need to convert from liters to moles. To do this, we divide the liters by 22.4, the amount of liters of a gas per mole.

32.2 / 22.4

= 1.4375 moles of CO₂

Now we want to convert from moles to grams. To do this, we multiply the moles by the molar mass of CO₂. The total molar mass can be found on the periodic table by adding up the molar mass of carbon (12) and two oxygen (32).

12 + 32 = 44

Now we want to multiply the moles by the molar mass.

1.4375 • 44

= 63.25 grams of CO₂

This is your answer.

Hope this helps!

How many moles of ions are produced by the dissociation of 1 mol of al2(co3)3?
zloy xaker [14]
Aluminium Carbonate on Dissociation produces Aluminium Ions and carbonate Ions as follow,

                            Al₂(CO₃)₃      →     2 Al⁺³  +  3 CO₃⁻²

Result:
          On dissociation Al₂(CO₃)₃ produces FIVE Ions in total. The Ions produced and there number are as follow;

                                              Al⁺²  =  2

                                            CO₃⁻²  =  3
