Answer:
The symbol of isotopes used for blood flow analysis is
<u>Explanation:
</u>
- Isotopes are the substances that exhibit the same atomic number but has a different mass number of an element.
- The atomic number explains the number of protons present in the element and mass number explains the number of neutrons available in the element.
- For blood flow analysis, the isotope element is cerium-141 and it is used in the chemical examination of blood flow particles.
- Symbol used for this isotope is
, where 141 indicates the amount of mass present and 58 indicates the proton number and 83 indicates neutron number present in that element.
- The amount of mass in an atom is calculated by the sum of protons and neutrons present in it. Thus mass of isotope is 141 obtained by the sum of 58 protons and 83 neutrons present in that isotope.
Answer:
42686.04375
Explanation:
847.3219*34.6=2317.33774 multiply this by the next number 1.4560 to get 42686.04375
Answer:
no one can answer your question because you have shown no arrows.
B and D is out. It cant be A because heat of combustion is substance not compound. So the answer is D.
This statement would be best characterized by the law of conservation of momentum—choice C.
