When a light bulb is turned on, it is powered by electricity and manages to produce both light and heat. This is something as persons we know from experience. Thus when a light bulb is turned on, ELECTRICAL ENERGY IS TRANSFORMED INTO LIGHT AND HEAT ENERGY. (Option B)
Answer:
Molar volume of gases
One mole of any gas has a volume of 24 dm3 or 24,000 cm3 at rtp (room temperature and pressure). This volume is called the molar volume of a gas.
This equation shows how the volume of gas in dm3 at rtp is related to the number of moles:
volume of gas at rtp = number of moles × 24

Answer:
Mass of ammonia = 34 g
Explanation:
Given data:
Number of molecules of ammonia = 1.204 × 10²⁴
Mass of ammonia = ?
Solution:
First of all we will calculate the number of moles.
one mole of ammonia = 6.022 × 10²³ molecules
n = 1 mole/6.022 × 10²³ molecules × 1.204 × 10²⁴ molecules
Number of moles = 2 mol
Mass of ammonia:
Number of moles = Mass / molar mass
Mass of ammonia = number of moles × molar mass
Mass of ammonia = 2 mol × 17 g/mol
Mass of ammonia = 34 g
