A: carbon
b: nitrogen
type of bond: covalent bond
formula: a3b4
Answer:
Explanation:
Hydrocarbon:
a = An organic compound made up of only carbon and hydrogen.
Such as alkane, alkene, alkyne.
Cyclic hydrocarbon:
c = Carbon chain that form rings.
Such as benzene, cyclo heptane etc
Isomers:
d = Compounds with same molecular formula and different structural formula.
Alkanes:
e = refers to saturated hydrocarbons, no matter the shape
such as methane, ethane, propane etc.
Alkene:
f = Any hydrocarbon that have at lest one carbon carbon double bond.
such as ethene, propene, butene
Saturated hydrocarbons:
b = Carbon atoms are saturated with so many hydrogen atoms that no more bonds may be formed
such alkanes.
Answer:
(C) Decomposition reaction
Explanation:
A decomposition reaction is a chemical reaction in which a single compound breaks down into two or more compounds or elements.
<u>in this example </u>
- 2KClO₃(s) ->2KCl (s) + 3O₂ (g)
Potassium chlorate (KClO₃) decomposed to two smaller compounds KCl and O₂ gas.
So, the right choice is (C) Decomposition reaction
molaity= moles/L
molarity= 5.0 moles/ 10 L
molarity= 0.5
Answer:
A
Explanation:
Percent yield= Actual yield/Theoretical yield x 100
The problem tells you that 6.33g of As is produced (actual yield), but 7.71g should be produced (theoretical yield). So 6.33/7.71= 0.821 x 100= 82.1%
