What are the two variables that affect the electric force between two objects?

Chemistry
1 answer:
givi [52]3 years ago
5 0

Explanation:

The electrical force between two objects is given by the formula as follows :

F=\dfrac{kq_1q_2}{d^2}

k is electrostatic constant

q₁ and q₂ are electric charges

d is distance between charges

So, the two force between two charged objects depends on the product of charges and distance between charges.

Calculate the volume in liters required to prepare a 5.00 m solution of nacl using 15.4 g of nacl
Vedmedyk [2.9K]
<span>52.7 ml First, determine how many moles of NaCl you have Atomic weight sodium = 22.989769 Atomic weight chlorine = 35.453 Molar mass NaCl = 22.989769 + 35.453 = 58.442769 g/mol Moles NaCl = 15.4 g / 58.442769 g/mol = 0.263505653 mol Now molarity is defined as moles/liter, so let's set up an equation for the number of liters we can make. molarity = moles/liter Substitute the known values 5.00 = 0.263505653/liter And solve for liters 5.00 = 0.263505653/liter 5.00* liter = 0.263505653 liter = 0.263505653/5.00 liter = 0.052701131 So you can make 0.0527 liters of the solution. Or 52.7 ml</span>

Consider the reaction: A (aq) ⇌ B (aq) at 253 K where the initial concentration of A = 1.00 M and the initial concentration of B
Ugo [173]

Answer:

The maximum amount of work that can be done by this system is -2.71 kJ/mol

Explanation:

Maximum amount of work denoted change in gibbs free energy (\Delta G) during the reaction.

Equilibrium concentration of B = 0.357 M

So equilibrium concentration of A = (1-0.357) M = 0.643 M

So equilibrium constant at 253 K, K_{eq}= \frac{[B]}{[A]}

[A] and [B] represent equilibrium concentrations

K_{eq}=\frac{0.357}{0.643}=0.555

When concentration of A = 0.867 M then B = (1-0.867) M = 0.133 M

So reaction quotient at this situation, Q=\frac{0.133}{0.867}=0.153

We know,  \Delta G=RTln(\frac{Q}{K_{eq}})

where R is gas constant and T is temperature in kelvin

Here R is 8.314 J/(mol.K), T is 253 K, Q is 0.153 and K_{eq} is 0.555

So, \Delta G=8.314\times 253\times ln(\frac{0.153}{0.555})mol/K

                           = -2710 J/mol

                            = -2.71 kJ/mol
