Answer:
chlorine is therefore an anion
No, this number is the result of the natural mixture of Cl-35 and Cl-37, which produces the observed <span>value.
</span><span>The mass of Cl on the periodic table is 35.45 atomic mass units. This is an average mass of the isotopes (different Cl atoms in nature). Most Cl atoms in nature have a relative mass of about 35 atomic mass units. Most of the remaining Cl isotopes have a relative mass of 37 atomic mass units. </span>
Atoms of Carbon along with hydrogen bonded to the carbons in the molecule are 2 main elements for the molecule to be organic.
It would be a chemical change because the chloride water would have an effect on the copper. A way to tell if something is a chemical or physical change is that chemical change is not reversible. Physical change can be reversed. For example, water can be physically changed into ice, and it can go back into water. Hope this helps!
Answer:
12
Explanation:
The coefficient of the CO2 shows the amount of CO2 needed in the reaction so to react with 11 water, 12 molecules of carbon dioxide is needed.
