Which of the following is a correct variation of the Joule's law equation? O A. P= I x R2 OB. P = V + OC. P = 12 V OD. P = V2 R​
Minchanka [31]

Answer:

P=\dfrac{V^2}{R}

Explanation:

Power is defined as the rate at which energy is dissipated.

Its mathematical form is given by :

P = VI

Where

V is voltage and I is current

Using Ohm's law :

I=\dfrac{V}{R}, R is resistance

Joule's law equation is given by :

P=\dfrac{V^2}{R}

Hence, the correct option is (d).

In experiment 1, how many moles of benzoic acid are present? how many moles of sodium bicarbonate are contained in 1 ml of a 10%
nexus9112 [7]

First, let us calculate the moles of solute or sodium bicarbonate is in the 1 ml solution.

<span>moles  = 1 mL * (1 g / 9 mL) = 0.11 moles</span>

 

The molar mass of sodium bicarbonate is 84 g/mol, therefore the mass is:

mass = 0.11 moles * 84 g/mol

<span>mass = 9.33 g</span>
