<em><u>Microwaves are very widely used in today’s world. They are used for point-to-point communication links, wireless networks, microwave radio relay networks, radar, satellite and spacecraft communication, medical diathermy and cancer treatment, remote sensing, radio astronomy, particle accelerators, spectroscopy, industrial heating, collision avoidance systems, garage door openers and keyless entry systems, and for cooking food in microwave ovens.</u></em></h3>
Petrol is primarily characterised by its octane number which defines its ability to burn efficiently and produce more energy per unit. A low octane petrol particle blast inside the engine instead of burning from spark this is called knocking as it produces knocking sound in the engine, to counter this an anti-knocking agent is added to petrol. Earlier Lead was used as an anti-knocking agent but it is highly toxic ,also the researchers who experimented lead with petrol died unnatural death. In later stages when effects of lead toxicity started showing up lead was replaced by benzene compounds as anti-knocking agents this is know as Unleaded petrol. Benzene is carcinogenic and started showing its ill effects after few years especially in densely populated cities. Govts have reduced the concentration of benzene in petrol thereafter and emphasised on implementation of Euro iv standards.
Answer:
114.4 grams of P₄O₁₀
Explanation:
P₄ + 5O₂ → P₄O₁₀
50 grams of P₄ are (50 g / 123.88 g/m) = 0.403 moles
Ratio is 1:1 so 0.403 moles of phosphorus can produce the same amount of P₄O₁₀.
Molar mass P₄O₁₀ = 283.88 g/m
0.403 moles . 283.88 g/m = 114.4 g
