The combustion of acetylene gas is represented by the following chemical equation: 2C2H2(g) + 5O2(g) ---> 4CO2(g) + 2H20(g)

1. How many liters of CO2 are produced when 5.20 L of C2H2 burn in oxygen?

2. How many liters of oxygen are required to burn 3.50 L of acetylene?

P4O10 > 4P + 5O2

3. How many moles of phosphorus would be produced if 2.5 mol of P4O10 reacted?

4. How many grams of oxygen would be produced if 1.6 mol P4O10 reacted?

4 Al + 3O2 > 2Al2O3

5. How many moles of Al are needed to form 2.3 grams of Al2O3?

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."

lol for the pointsss
