4. solid zinc sulfide forms when zinc metal and sulfur powder are heated.\n5. when sodium metal reacts with iron (iii) chloride, iron metal and sodium chloride are formed.\n6. aluminum chloride and hydrogen gas are produced when aluminum metal and hydrogen chloride gas are heated.\n7. when isopropanol (c₃h₈o) burns in oxygen, carbon dioxide and water are produced.
Answer
Explanation:
Step1: Write the chemical equation for reaction 4
$Zn(s)+S(s)\xrightarrow{\Delta}ZnS(s)$
Step2: Write the chemical equation for reaction 5
$3Na(s)+FeCl_{3}(s)\rightarrow Fe(s) + 3NaCl(s)$
Step3: Write the chemical equation for reaction 6
$2Al(s)+6HCl(g)\xrightarrow{\Delta}2AlCl_{3}(s)+3H_{2}(g)$
Step4: Write the chemical equation for reaction 7
$2C_{3}H_{8}O(l)+9O_{2}(g)\rightarrow 6CO_{2}(g)+8H_{2}O(g)$
Answer:
Reaction 4: $Zn(s)+S(s)\xrightarrow{\Delta}ZnS(s)$ Reaction 5: $3Na(s)+FeCl_{3}(s)\rightarrow Fe(s) + 3NaCl(s)$ Reaction 6: $2Al(s)+6HCl(g)\xrightarrow{\Delta}2AlCl_{3}(s)+3H_{2}(g)$ Reaction 7: $2C_{3}H_{8}O(l)+9O_{2}(g)\rightarrow 6CO_{2}(g)+8H_{2}O(g)$
