Which radioisotope has the fastest rate ofdecay? (1) 14C (2) 37Ca (3) 53Fe (4) 42K
Answers
Answer 1
Answer:
The correct answer is 2. 37Ca.
The fastest rate of decay in radioisotope is 37Ca. Another name for radioisotope is radioactive of isotopes which are of given element.
The different number of neurons and the same number of protons are present on the same element with different isotopes. Radioisotopes are considered to have an unstable combination of neutrons and protons.
Answer 2
Answer:
The correct answer to this question is (2) 37Ca . The radioisotope that has the fastest rate of decay is 37Ca. Radioisotope or also known as radioactive isotopes of a given element. Same number of protons but different number of neurons are present on different isotopes of the same element. They are considered as atoms that have unstable protons and neutrons combination.

Chlorine has two naturally occuring isotopes - chlorine-35 and chlorine-37. Elaborate on how the atomic mass is determined given that chlorine-35 has an abundance of 75.78% and has a mass of 34.969 amu and that chlorine-37 has an abundance of 24.22% and a mass of 36.966 amu.
Answers
because the gmm for chlorine is 35.5 which is the average of all of those combined, so the percentages reflect how much of each isotope is needed to make the average that specific mass per mole

Which two substances bind using a lock-and-key mechanism?enzyme and substrate reactant and substrate substrate and product reactant and product
Answers
The answer is the first option. Enzyme and substrate bind using a lock-and-key mechanism. Enzymes act on a specific substrate and a substrate needs a specific enzyme, this is what is called a lock-and-key mechanism. Enzymes and substtates are like a key and a lock, one is for each other.
it would be A: enzyme and substrate
What can the arrow in a chemical reaction be translated to mean?
Answers
When a chemical equation is written out, there will be an arrow to represent the chemical reaction occurring. In the equation 6H20+6CO2-->6C12H6O+6O2, the part before the arrow is what you start out with. Next comes the arrow, or the reaction. After the reaction, you have the end product.
Answer:
The arrow means "yield" or "react to form".
Explanation: The arrow means "yield" or "react to form".
Which chemical class does phenobarbital belong to?
Answers
Phenobarbital is derivative of Barbituric Acid and Barbituric Acid is derivative of Urea. (structures shown in Fig below)
Urea has H₂N- group attached to Carbonyl Group (C=O), and such class of comounds conataining H₂N-C=O bond are called as Amides.
