NO.OF.MOLES= MASS/ATOMIC MASS
THE ATOMICITY OF SULPHUR IS 8 AND ITS MASS NUMBER IS 32.
SO, THE ATOMIC MASS IS 256
NO.OF.MOLES= 53.7/256
= 537/2560
= 0.2097
Answer:
endothermic reaction
Explanation:
This is because it absorb heat from the surrounding which is required to break the bond hold it together hence as it absorb heat from the surrounding the temp of surrounding decrease.
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>
