Answer:
1) during a phase change: particles overcome forces of attraction and temperature stays the same not during a phase change: temperature rises 2)Particle motion decreases, and electrostatic forces pull particles closer together.
3) Gases fill their container, showing that gas particles are not tied together and can move far apart.
Explanation:
Answer:
A normal atom has a neutral charge. When you are missing electrons it has a positive charge. When you have extra electron, you have a negative charge. I am not sure what the answer to your second question is, sorry.

Hey there !
<span>Balanced equation:
1 MgS +1 Na2O = 1 Na2S + 1 MgO
</span>
MgS = 1
Na2O = 1
Na2S = 1
MgO = 1
Answer D
Answer:
Explanation:
word equation:
a) Bromine + potassium iodide → potassium bromide + iodine
Chemical equation:
Br₂ + KI → KBr + I₂
Balanced chemical equation:
Br₂ + 2KI → 2KBr + I₂
B) word equation:
Iodine + potassium astatide → potassium iodide + astatine
Chemical equation:
I₂ + KAt → KI + At₂
Balanced chemical equation:
I₂ + 2KAt → 2KI + At₂
c) word equation:
chlorine + sodium iodide → sodium chloride + iodine
Chemical equation:
Cl₂ + NaI → NaCl + I₂
Balanced chemical equation:
Cl₂ + 2NaI → 2NaCl + I₂
d) word equation:
fluorine + sodium bromide → sodium fluoride + bromine
Chemical equation:
F₂ + NaBr → NaF + Br₂
Balanced chemical equation:
F₂ + 2NaBr → NaF + Br₂
e) word equation:
fluorine + potassium chloride → potassium fluoride + chlorine
Chemical equation:
F₂ + KCl → KF + Cl₂
Balanced chemical equation:
F₂ + 2KCl → KF + Cl₂
