If a light bulb has a resistance of 10 Ohms, and it has 25 Amps of current flowing, what is the Voltage of its battery?V=IR

250 Volts.

Explanation:

Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.

Mathematically, Ohm's law is given by the formula;

Where;

Given the following data;

Resistance = 10 ohms

Current = 25 amps

Substituting into the equation, we have;

V = 250V.

Therefore, the voltage of its battery is 250 volts.

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
