Answer:
Silicon tetrachloride gas reacts with solid magnesium metal producing solid silicon and solid magnesium chloride.
SiCl₄(g) + Mg(s) → Si(s) + MgCl₂(s)
Explanation:
The reaction of SiCl₄(g) with Mg(s) produce Si(s) and MgCl₂(s). A way to write a word equation could be:
<em>Silicon tetrachloride gas reacts with solid magnesium metal producing solid silicon and solid magnesium chloride</em>.
The unbalanced formula equation including physical states is:
<em>SiCl₄(g) + Mg(s) → Si(s) + MgCl₂(s)</em>
Answer:
Your answer is D. It is the heat required to change a gram of substance from a liquid to a gas.
Answer:
20 electrons
Explanation:
The atomic number equals the amount of protons in an atom's nucleus, but this number is also equal to the amount of electrons. So if the atomic number is 20, that means there are 20 protons and 20 electrons. ( they need to balance out since they have opposite charges)
I hope that helps :)
If oxygen has 8 valence electrons on it last ring then oxygen will be stable.
