the correct empirical formula for C6H12O6 is CH2O...
hope it will help....
Radioactive isotopes eventually decay, or disintegrate, to harmless materials. Some isotopes decay in hours or even minutes, but others decay very slowly. Strontium-90 and cesium-137 have half-lives of about 30 years (half the radioactivity will decay in 30 years). <u>Plutonium-239 has a half-life of 24,000 years.</u>

<h3>What is radioactive decay? </h3>
Radioactive decay is the emission of energy in the form of ionizing radiation. The ionizing radiation that is emitted can include alpha particles, beta particles and/or gamma rays. Radioactive decay occurs in unbalanced atoms called radionuclides.
Elements in the periodic table can take on several forms. Some of these forms are stable; other forms are unstable. Typically, the most stable form of an element is the most common in nature. However, all elements have an unstable form. Unstable forms emit ionizing radiation and are radioactive. There are some elements with no stable form that are always radioactive, such as uranium. Elements that emit ionizing radiation are called radionuclides.

<u>Answer:</u> The time required for the conversion of benzoyl chloride to benzoic acid is 390 seconds.
<u>Explanation:</u>
The expression for the rate law of first order kinetics is given as:
......(1)
where,
= initial mass of isotope = 100 g
N = mass of the parent isotope left after the time = 100 - 25 = 75 g
t = time taken = 26 s
k = rate constant = ?
Putting values in above equation, we get:
Now, we need to find the time when 99 % of the reaction is complete. Using equation 1 again, we get:
= initial mass of isotope = 100 g
N = mass of the parent isotope left after the time = 100 - 99 = 1 g
t = time taken = ? s
k = rate constant = 
Putting values in above equation, we get:
Time required for the conversion of benzoyl chloride to benzoic acid = 416 - 26 = 390 s
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 .
