When two fluorine atoms bond together in F2, what type of covalent bond do they form?

makvit [3.9K]

When two fluorine atoms bond together in f2 the type of covalent bond do they form is non-polar covalent bond.

Explanation

They are two type of covalent bond. that is non polar covalent bond and polar covalent bond.

Non polar covalent bond is formed when atoms share a pair of electrons with each other equally.

polar covalent bond is bond formed when atoms share a pair electrons unequally.

F2 is a non polar since it is made up of two same atoms which has the same electronegativity, therefore equal number of electrons exist in the orbital overlap.

Find the volume of a gas if 3.6 mols of the gas is at STP

Digiron [165]

Answer:

81 L gas

General Formulas and Concepts:

Ideal Gas Law

STP (Standard Conditions for Temperature and Pressure) = 22.4 L per mole at 1 atm, 273 K

Stoichiometry

Using Dimensional Analysis

Explanation:

Step 1: Define

[Given] 3.6 mols gas at STP

[Solve] volume (L) of gas

Step 2: Convert

[DA] Set up: $\displaystyle 3.6 \ mol \ gas(\frac{22.4 \ L \ gas}{1 \ mol \ gas \ at \ STP})$
[DA] Multiply [Cancel out units]: $\displaystyle 80.64 \ L \ gas$

Step 3: Check

Follow sig fig rules and round. We are given 2 sig figs.

80.64 L gas ≈ 81 L gas
