Answer:
Chlorine has strong inter molecular forces than iodine
Explanation:
Atomic number, atomic mass, symbol of element
The nature of ions formed by different atoms is as follows:
- Metal atoms form positively-charged ions
- Non-metal atoms form negatively-charged ions
<h3>What are ions?</h3>
Ions are substances which are formed when neutral atoms gain or lose electrons.
There are two types of ions based on the charge the ion carries;
- anions - which are negatively-charged
- cations - which are positively-charged
The nature of the ions formed by different atoms depend on whether the atoms are atoms of metals or atoms of non-metals.
Metal atoms form positively-charged ions by the loss of one or more electrons as illustrated below:
where; M is a metal atom, M⁺ is a metal ion, and e⁻ is an electron.
Non-metal atoms form negatively-charged ions by the gain of one or more electrons as illustrated below:
where; N is a non-metal atom, N⁻ is a non-metal ion, and e⁻ is an electron.
In conclusion, the nature of ions formed by atoms depends on the nature of the atom, whether they are metallic or non-metallic atoms.

Answer: 
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
Thus in the reactants, there are 2 atoms of hydrogen and 2 atoms of iodine .Thus there has to be 2 atoms of hydrogen and 2 atoms of iodine in the product as well. Thus a coefficient of 2 is placed in front of HI.
The balanced chemical reaction is:
Answer:
lungs and blood vessels, airway
Explanation:
because the respiratory system are a system that helps people breate. the lungs breathe in oxygen and then breathe out carbon dioxide. the blood vessels carries the oxygen into the body to other part of the system in the body that needed oxygen to make glucose.
