Answer: The concentration of the acid is 0.01 moles acid/0.040 L = 0.25 moles/L = 0.25 M
Explanation:
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.
A refugee is illegal until they have the proper paperwork for that specific country they are trying to get into.
The number of covalent bonds is determined by the number of valence electrons of an element. The number of electrons tells the maximum number of bonds an element allows. In this case, an oxygen atom requires two bonds. So for Sio2, each oxygen atoms are bonded in double bonds to Si. Hence there are two covalent bonds.
NaHCO3 is a product of a strong base and a weak acid reaction. Thus it has weak basic properties.
HCO3- ion is actually amphoteric, which means it can act as a base or an acid. But it is weaker than a strong acid or a strong base.
<span>HCO3- is amphoteric meaning it acts both as a B.L. Acid and a B.L. Base.. which is why it's used to neutralize both acid and base spills in the lab.</span>
