The answer is:  [C]:  "4" .
___________________________________________________
Note:  To balance this equation, the coefficient, "4", should be placed in front of the PCl₃ ;  and the coefficient, "6", should be placed in front of the Cl₂ .
________________________________________________________
The balanced equation is:
__________________________________________________
             P₄ (s) + 6 Cl₂ (g)  <span>→ 4 </span>PCl₃ (l)   .

Reil [10]

Answer:

Yes

Explanation:

When an object has more mass it takes more gravity to keep it down therefore producing friction which in return reduces the amount of kinetic energy created. A change in an object's speed has an greater effect on its kinetic energy. than a change in its mass has, because kinetic energy is proportional to.

Two positive charges of 2.8 x 10^-6 are separated by 0.50m. What force exists between the two charges?
Damm [24]
F = k(Q₁Q₂)/r²
where k is Coulomb's constant 8.99e9 
F = 8.99e9(2.8e-6)²/0.5² = 0.2819N

An uncharged 30.0-µF capacitor is connected in series with a 25.0-Ω resistor, a DC battery, and an open switch. The battery has
kolezko [41]

Answer:

(a) Maximum current through resistor is 1.43 A

(b) Maximum charge capacitor receives is 1.50\times 10^{-3}\text{ C}.

Explanation:

(a)

In an RC (resistor-capacitor) DC circuit, when charging, the current at any time, <em>t</em>, is given by

I(t) = I_0e^{-t/\tau}

Here, I_0 is the maximum current and <em>τ</em> represents time constant which is given by RC (the product of the resistance and capacitance).

The maximum current is given by

I = \dfrac{V}{R_\text{eff}}

<em>V</em> is the emf of the battery and R_\text{eff} is the effective resistance.

In this question, R_\text{eff} = 10.0 Ω + 25.0 Ω = 35.0 Ω

I = \dfrac{50.0\text{ V}}{35.0\ \Omega} = 1.43\text{ A}

(b) The maximum charge is given

<em>Q</em> = <em>CV</em>

where <em>C</em> is the capacitance of the capacitor

Q = (30.0\times10^{-6}\text{ F})(50.0\text{ V}) = 1.50\times 10^{-3}\text{ C}

Calculate the capacitance of a system that stores 9.4 x 10-10 C of charge at
natka813 [3]

Answer:

A. 1.88\times 10^{-11}\,F.

Explanation:

By definition of Electric Capacitance, the capacitance of the system (C), in farads, is described by the following formula:

C = \frac{q}{V} (1)

Where:

q - Electric charge, in coulombs.

V - Voltage, in volts.

If we know that q = 9.4\times 10^{-10}\,C and V = 50\,V, then the capacitance of the system is:

C = \frac{9.4\times 10^{-10}\,C}{50\,V}

C = 1.88\times 10^{-11}\,F

The correct answer is A.
