Answer:
(4,20)
Explanation:
Oxygen di-fluoride or OF2 is a polar molecule, formed through the covalent bonding between one Oxygen and two Fluorine atoms.
Oxygen has atomic no. 8 and its electronic configuration is as below:
Oxygen has 4 electrons in the valence shell. It has the ability to share two electrons with other atoms through covalent bond and get stable.
The atomic number of Fluorine is 7, and its electronic configuration is as:
So, Fluorine atom has the capacity to accept 1 electron to form 1 covalent bond or in the formation of the F- ion.
The structure of OF2 is a bent structure with O atom sandwiched by two fluorine atoms like F-O-F. So there are two electrons on oxygen atom that are taking part in the formation of covalent bond with each Fluorine atom (Please dot structure in figure).
Now we can easily calculate no of bonding and non-bonding electrons.
- No. of bonding electrons = 4 (two from oxygen and two from fluorine atoms each)
- No. of non-bonding electrons= 20 (6+6 from two Fluorine atoms and 6 from Oxygen atom)
Hope it helps! :)
<span>The chemical equation for the Vinegar & Baking Soda reaction is:
NaHCO3(s) + CH3COOH(l) → CO2(g) + H2O(l) + Na+(aq) + CH3COO-(aq)
with s = solid, l = liquid, g = gas, aq = aqueous or in water solution
Another reaction is:
NaHCO3 + HC2H3O2 → NaC2H3O2 + H2O + CO2
The chemical reaction actually occurs in two steps.
First, there is double displacement reaction in which acetic acid in vinegar reacts with sodium bicarbonate to form sodium acetate and carbonic acid:
NaHCO3 + HC2H3O2 → NaC2H3O2 + H2CO3
Then,Carbonic acid is unstable and undergoes a decomposition reaction to produce the carbon dioxide gas:
H2CO3 → H2O + CO2</span>
<span>On a molar a basis, the most effective bleaching agent kbro3 has more oxygen, but due to the bromine, it would make things look yellowish. The bromine would counteracts the bleaching effect. As we all know, bleach is naocl or hypochlorite</span>
Answer:
1. Covalent bonds can form between two nonmetal atoms.
2. Covalent bonds can form between atoms of the same element.
3. Covalent bonds can form between atoms of different elements.

Answer:
290 grams
Explanation:
Let's begin by writing the balanced chemical equations:
Then we calculate the number of moles in 97g of propane.
n(propane)=
According to the balanced chemical equation, one mole of propane produces 3 moles of carbon dioxide. So the available number of moles of propane must be multiplied by three to work out the number of carbon dioxide produced.
n(carbon dioxide)= 2.1995mol*3 = 6.5985mol
mass(carbon dioxide) = moles * molar mass
= 6.5985 mol * 44.01 g/mol
= 290 grams
