To calculate the activity of carbon-14 in becquerels, we need a conversion factor to multiply to the value given above. Base on my research, I found that <span>1 Ci = 3.70x10^10 Bq. We convert as follows:
</span>54.7 μCi = 54.7 x 10^-6 Ci ( 3.70x10^10 Bq / 1 Ci ) = 2.02 x 10^6 Bq
Hope this answers the question. Have a nice day.
Answer:
Decomposition or cracking
Explanation:
Decomposition reaction is a chemical change in which a single compound is broken down into two or more simpler products.
For example;
A → B + C
The driving force of such reaction is the high positive heat of formation of the compound which indicates that they are highly unstable.
Some stable compounds also decompose when subjected to high temperature and pressure.
Answer:
C-14 => N-14 + β⁻
Explanation:
C-14 over time decays by beta emission to N-14. Before decay, C-14 nucleus contains 6 protons and 8 neutrons. It is accepted that a neutron (n°) is composed of 1 proton (p⁺) and 1 electron (e⁻). Beta emission indicates loss/discharge of a high energy e⁻ from the nucleus of C-14 leaving 7 protons and 7 neutrons. The number of protons defines the element, N-14 as a product of the decay process with the β particle (high energy electron) the other. To check, remember, the ∑mass Reactants = ∑mass Products (superscript numbers) and ∑reactant charges = ∑product charges (subscript numbers
₆C¹⁴ => ₇N¹⁴ + ₋₁e° or, C-14 => N-14 + β
Answer:
B it is decomposition reaction
