What does two bonded flurione atoms form?

Archy [21]

2 Fluorine atoms covalently bonded with each other, each sharing an equal number of a single, one valence electron to achieve a stable octet, would form a diatonic fluorine gas. It is a diatomic molecule, a molecule consisting of 2 atoms that are the same, in this case fluorine.

Rank the six combinations of electric charges on the basis of the electric force acting on q1. Define forces pointing to the rig

m_a_m_a [10]

Answer:

Explanation:

Let's define positive to be right. The net force on q2 is the

vector sum of the forces from q1 and q3.

The force has a magnitude of and points to the left.

Handling the signs correctly is critical. The negative signs

come from the direction of each of the forces (both to the left),

not from the signs of the charge.

2. Both charges 1 and 3 have 1 close

neighbor and 1 far neighbor. Will

they experience forces of the same

magnitude?

No, because both forces acting on charge 1 are in the same

direction, while the two forces acting on charge 3 are in

opposite directions. Thus, 1 > 3.

Both charges 1 and 2 have two forces acting in the same

direction. Will they experience forces of the same magnitude?

No, because one force acting on charge 1 is the same

magnitude as one acing on charge 2, while the second force

acting on charge 1 is smaller – it comes from a charge farther away

masha68 [24]

Answer:

The equilibrium law

Explanation:

According to the equilibrium law , when $\text{concentration}$ of any of the reactants or the products in the reaction at an equilibrium state, is changed, then it changes the composition of equilibrium mixture in order to minimize the effect of

Acetic acid (in excess) + $\text{alcohol}$ ⇄ $\text{ester}$ + water

$\text{Fischer esterification}$ is a reaction which involves the equilibrium. So to force the reaction towards the side of $\text{ester}$ , one of the reactant is taken in excess. All this can be explained easily by applying the equilibrium law.

How much volume will 8.8 moles of gas fill at 0.12 atm at 56*C

Neporo4naja [7]

Answer:

2000 L

General Formulas and Concepts:

Atomic Structure

Moles
Temperature Conversion: K = °C + 273.15

Gas Laws

Ideal Gas Law: PV = nRT

P is pressure
V is volume (in L)
n is number of moles
R is gas constant
T is temperature (in K)

Explanation:

Step 1: Define

[Given] 8.8 moles gas

[Given] 0.12 atm

[Given] 56 °C = 329.15 K

Step 2: Solve for V

Substitute in variables [Ideal Gas Law Formula]: $\displaystyle (0.12 \ atm)V = (8.8 \ mol)(0.0821 \ \frac{L \cdot atm}{mol \cdot K})(329.15 \ K)$
Isolate V: $\displaystyle V = \frac{(8.8 \ mol)(0.0821 \ \frac{L \cdot atm}{mol \cdot K})(329.15 \ K)}{(0.12 \ atm)}$
Multiply/Divide [Cancel out units]: $\displaystyle V = 1981.7 \ L$

Step 3: Check

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

1981.7 L ≈ 2000 L
