Answer:
34.8 mL
Explanation:
First we <u>convert 5.48 g of CuNO₃ into moles</u>, using its<em> molar mass</em>:
- 5.48 g CuNO₃ ÷ 187.56 g/mol = 0.0292 mol
Now we can <u>calculate the volume of the solution</u>, using the <em>definition of molarity</em>:
- Molarity = moles / liters
- 0.840 M = 0.0292 mol / liters
Finally we <u>convert L into mL</u>:
- 0.0348 L * 1000 = 34.8 mL
Bones, muscles, and tendons
Answer:
=71.76 grams
Explanation:
At Room temperature and pressure, 1 mole of an ideal gas occupies a volume of 24 liters.
Therefore, the number of moles occupied by 28.7 L is:
(28.7×1)/24=1.196 moles.
Mass=Number of moles× RMM
RMM of N₂O₂ is 60
mass=1.196 moles× 60 grams/mol
=71.76 grams
Is not a single replacement
<h3>Further explanation</h3>
A single replacement reaction is a chemical reaction in which one element replaces the other elements of a compound to produce new elements and compounds
Reactions
A+BC--> AC+B
Metal halogens can force metal halide ions in the order F> Cl> Br> I
Oxidation : F₂> Cl₂> Br₂> I₂
Reaction
NaBr+I₂ -> NaI+Br₂
Then the reaction will not occur because I₂ cannot oxidize Br, or the reaction is said to be non-spontaneous
