Answer:
The same element that contain equal number if protons but different number of neurons in their nuclei and hence differ in relative atomic mass
Calculate the mass defect and nuclear binding energy of an atom ... To convert to joules per nucleon, simply divide by the number of nucleons.
Answer: 
Explanation:
A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.
Spectator ions are defined as the ions which does not get involved in a chemical equation or they are ions which are found on both the sides of the chemical reaction present in ionic form.
The given chemical equation is:

The complete ionic equation is:

The ions which are present on both the sides of the equation are lithium and chlorate ions. and hence are not involved in net ionic equation.
Thus the net ionic equation is:

Answer:
kill beneficial organisms in addition to the targeted pest
Explanation:
The use of pesticides have emerged as one of the main options used in the control of invertebrate pests in different parts of the world. Organophosphate is the mostly used form of pesticide in places like Australia. There have been reported issues of crops losses from the incidences of pests, despite the increase in the use of pesticides. Broad spectrum pesticides end up kill non-target invertebrate species together with the insects and mites they are out to eliminate
