Answer: atoms
Explanation:
All matter is made up of smaller indivisible particles called atoms. These atoms are the smallest units of matter ACCORDING to the Dalton's Atomic theory.
Molecules are combined atoms, while cells and phospholipids are complex combination of atoms.
Therefore, atoms is the answer
Answer:
a. 0.933 M⁻¹.cm⁻¹
b. 0.003 M/s
Explanation:
a. The molar absorptivity coefficient (ε) is the ability of 1 mol of the substance to mitigate the light of a wavelength. It means that it's a measure of how strong a substance can absorb radiation. It can be calculated by the absorbance (A), the concentration (c) and the length of the cuvette (l).
ε = A/(c*l)
Thus, at t = 0, for the blue reactant, A = 0.77, c = 0.75 M, l = 1.10 cm.
ε = 0.77/(0.75*1.10)
ε = 0.933 M⁻¹.cm⁻¹
b) The rate of the reaction can be found by the rate of desapering of the blue reactant. Let's find the concnetration when t = 30.00 s:
ε = A/(c*l)
0.933 = 0.67/(c*1.10)
1.10c = 0.67/0.933
1.10c = 0.7181
c = 0.65 M
Thus, the rate is the variation of the concentration divided by the time variation:
r = (0.75 - 0.65)/30
r = 0.003 M/s
Because the coefficient of the blue reactant is 1, the rate of reaction is equal to the rate of disappearing of B, 0.003 M/s.

उस पदार्थ या यौगिक को अभिकर्मक (reagent) कहते हैं जो किसी तंत्र में रासायनिक अभिक्रिया उत्पन्न करने के लिये डाला या मिलाया जाता है। उस पदार्थ को भी अभिकर्मक कहेंगे जिसे यह जांचने के लिये मिलाया जाता है कि कोई अभिक्रिया होती है या नहीं। इस तरह के कुछ वैश्लेषिक अभिकर्मक हैं - फेहलिंग का अभिकर्मक (Fehling's reagent), मिलॉन का अभिकर्मक (Millon's reagent) तथा टॉलीन का अभिकर्मक (Tollens' reagent)।
