Someone please help asap What general trend does electronegativity follow on the periodic table?
Dahasolnce [82]
On the periodic table, electronegativity generally increases as you move from left to right across a period and decreases as you move down a group. As a result, the most electronegative elements are found on the top right of the periodic table, while the least electronegative elements are found on the bottom left.

Two spherical shells have a common center. A -1.50 × 10-6 C charge is spread uniformly over the inner shell, which has a radius
Murrr4er [49]

Answer:

a) At 0.20 m, the magnitude of the field is 675.0 kV

The direction of the field is acting outwards from the center of the charged spheres

b) At 0.10 m, the magnitude of the field is 135 kV

The direction is acting outwards from the center of the charged spheres

c) At 0.025 m

The magnitude of the field, V = -270.0 kV

The direction of the field is inwards, towards the center of the charged spheres

Explanation:

The charged spherical shell parameters are;

The charge on the inner sphere, q₁ = -1.50 × 10⁻⁶ C

The radius of the inner shell, R₁ = 0.050 m

The charge on the outer sphere, q₂ = +4.50 × 10⁻⁶ C

The radius of the outer shell, R₂ = 0.15 m

Let 'r', represent the distance at which the electric field is measured, the following relationships can be obtained;

When r < R₁ < R₂,

V = k \cdot \left( \dfrac{q_1}{R_1} + \dfrac{q_2}{R_2} \right )

When R₁ < r < R₂,

V = k \cdot \left( \dfrac{q_1}{r} + \dfrac{q_2}{R_2} \right )

When R₁ < R₂ < r,

V = k \cdot \left( \dfrac{q_1  + q_2}{r^2}  \right )

a) When r = 0.20 m, we have;

R₁ < R₂ < r, therefore

V = k \cdot \left( \dfrac{q_1  + q_2}{r^2}  \right )

By plugging in the values, we get;

V = 9 \times 10^9 \times \left( \dfrac{-1.50 \times 10^{-6} + 4.50\times 10^{-6} }{0.20^2}  \right ) = 675.0 \ kV

Therefore, the magnitude of the field, V = 675.0 kV

The direction of the field is outwards

b) When r = 0.10 m, we have;

When R₁ < r < R₂, therefore;

V = k \cdot \left( \dfrac{q_1}{r} + \dfrac{q_2}{R_2} \right )

By plugging in the values, we get;

V = 9 \times 10^9 \times \left( \dfrac{-1.50 \times 10^{-6}  }{0.10}  + \dfrac{4.50\times 10^{-6}}{0.15} \right ) = 135 \ kV

Therefore, the magnitude of the field, V = 135 kV

The direction of the field is outwards from the center

c) When r = 0.025 m, we have;

When r < R₁ < R₂, therefore;

V = k \cdot \left( \dfrac{q_1}{R_1} + \dfrac{q_2}{R_2} \right )

By plugging in the values, we get;

V = 9 \times 10^9 \times \left( \dfrac{-1.50 \times 10^{-6}  }{0.05}  + \dfrac{4.50\times 10^{-6}}{0.15} \right ) = -270 \ kV

Therefore, the magnitude of the field, V = -270.0 kV

The direction of the field is inwards, towards the center of the charged spheres.

A neutral boron atom has 6 neutrons and 5 electrons. How many protons does it have?
frez [133]
5 because there is 5 electrons. In order for an atom to be neutral it has to have the same amount of positive and negative charges.

A system does 506 kj of work, and loses 266 kj of heat to the surroundings. what is the change in internal energy of the system?
babunello [35]

Answer:

The change in internal energy of the system = -772kJ

Explanation:

Given :

Heat lost by the system , a = -266KJ

Workdone by the system, W = -506KJ

The first law of thermodynamics states that:

Change in internal energy = q + w

Substituting values into the equation

Change in internal energy = (-266KJ) + (-506KJ)

Change in internal energy = -722KJ
