Lower left corner and the upper right corner before the noble gases

Number of valence electrons

Explanation:

The most reactive elements are the most electropositive and electronegative elements.

Francium is the most reactive metal and flourine the most reactive non-metals.

Francium is the most electropositive metal and fluorine is the most electronegative non-metal.

Electropositivity is the ability of an atom to willingly lose its valence electrons. This is typical of metals.

Electronegativity is the ability of atoms to attract the shared electrons to themselves in a bond.

An element is more reactive than another based on the number of valence electrons it has.
The valence electrons determines how reactive an atom is or would be.
Elements that requires just one or two electrons to complete their octet would be highly reactive and dire need to find such electron.
Also, elements with just an electron above the stable configuration will easily want to lose it.
Elements with a complete configuration will not be reactive.

The valence electrons are the electrons in the outer most shell of an atom used in chemical bonding.

Bread dough rises due to the formation of gas.

Explanation:

If we observe the outer part of the bread, which contains tiny hole like structure, due to the gas formation inside the bread dough.

In the bread dough rising process, the industries are using the yeast, which makes the gas that separates the protein particles in the bread move apart and makes the dough of the bread rise.

In this reaction, the yeast utilizing the carbohydrate to make a gas namely carbon-di-oxide gas which makes the dough to rise

When 3.00 g of sulfur are combined with 3.00 g of oxygen, 6.00 g of sulfur dioxide (SO2) are formed. What mass of oxygen would b

bazaltina [42]

Actually, we can answer the problem even without the first statement. All we have to do is write the reaction for the production of sulfur trioxide.

2 S + 3 O₂ → 2 SO₃

The stoichiometric calculations is as follows:

6 g S * 1 mol/32.06 g S = 0.187 mol S
Moles O₂ needed = 0.187 mol S * 3 mol O₂/2 mol S = 0.2805 mol O₂
Since the molar mas of O₂ is 32 g/mol,
Mass of O₂ needed = 0.2805 mol O₂ * 32 g/mol = 8.976 g O₂
