Answer:
Fe is the limiting reagent
Explanation:
The Solar System may be divided by its components into three major regions: the inner system, the near outer system, and the far outer system. The near outer system might also be referred to as the middle system.
Our solar system consists of our star, the Sun, and everything bound to it by gravity — the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune, dwarf planets such as Pluto, dozens of moons and millions of asteroids, comets and meteoroids.
Goodluck my friend!!
Answer:
CH₃(CH₂)₁₀COONa
Explanation:
The compounds given are
NaCl
CH₃COOH
CH₃COONH₄
CH₃(CH₂)₁₀COONa
CH₃(CH₂)₁₀CH₃
CH₃(CH₂)₁₀COONa will form micelle . Micelle are formed by soap solution which helps in the removal of oily dirt from our clothes . They are spherical shaped tiny droplet of oil which contains the tail of long chain organic compound like salt of long chain fatty acids . The surface of the droplet is lined with the tip of the chain which consists of negative charge of the tail end . On the average , each micelle contains a specific amount of charge . Due to it , they make colloidal solution in the water and gets washed off my water . The oily dirt is thus removed .
CH₃(CH₂)₁₀COONa ⇄ CH₃(CH₂)₁₀COO⁻ + Na⁺
CH₃(CH₂)₁₀COO⁻ part which is long chain of fatty acid gets adsorbed by oily droplet formed by oily dirt and forming micelle .
Reaction.-
2H2 + O2 ---> 2H2O
Given,
Mass of Oxygen - 25.0 g
Mass of Hydrogen - 42.0 g
now we have to calculate moles
moles of O2 = 25/16 = 1.5625 moles
Moles of H2 = 42/2 = 21 moles
Hydrogen gas is in excess,
now using reaction
1 mole of oxygen gas forms 2 moles of H2O
1.5625 mole of Oxygen gas will form x mole of H20
x = 3.125 moles
molar mass of H2O is 18g
mass of 3.125moles of water = 3.125 × 18 = 56.25 g.
Hence the mass of water produced when 25.0g of oxygen gas react with 42.0g of hydrogen gas is 56.25 grams
