Answer:
The correct answer is physical properties and/or phase properties.
Explanation:
Chemical properties can alter the substance (if you burn wood, it becomes ash and is no longer wood).
Reactive properties are also chemically changing the substance.
Phase properties are where the element can be in solid, liquid, or gas form so these could also be an answer.
I think it would lose its heat faster than the plastic bags because of higher conductivity feature.
<h3>What is conduction?</h3>
Conduction is the process in which heat or electricity is transmitted or transferred through the material of a substance without movement of the material.
We know that metals are good conductors so we can conclude that it would lose its heat faster than the plastic bags bof higher conductivity feature.

Explanation:
P₄+O₂=P₂O₃; non-balanced
P₄+O₂=2P₂O₃; to add '2' on the right side; non-balanced
P₄+3O₂=2P₂O₃. to add '3' before O₂ in the left side; balanced
<u>Answer:</u>
<em>An atom accepts electrons and becomes an anion.</em>
<em></em>
<u>Explanation:</u>
Atomic number = number of electrons = number of protons.
Atomic number of sodium is 11
So the atom contains 11 protons and 11 electrons
To find the number of neutrons we make use of the formula
Mass number - atomic number = number of neutrons
From the periodic table, we know mass number of sodium is 23
So number of neutron = 23 - 11 = 12.
When a sodium atom loses an electron it will have 11 positive protons and 10 negative electrons. Since 1 positive charge is more, Na becomes 
.
Positively charged ion is called as cation
Chlorine's atomic number is 17 so it has 17 protons and 17 electrons.
When it gains an electrons, it will have 17 positive protons and 18 negative electrons. Since 1 negative charge is more, Cl becomes 
.
Negatively charged ion is called as anion.
Answer:
Belgium and the Netherlands swap land near Lanaye and Oost-Maarland over the discovery of a headless body several years prior, which the Belgian Authorities could not access without crossing Dutch territory. The border has been straightened out and now runs down the center of the Meuse River.[5] The change took effect on 1 January 2018.
