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
Answer:
Option D will be the answer.
The given data states that the 2-D diagram is representing Lithium molecule.
few things one must know before solving the question,
Lithium is a Alkali metal having 3 electrons, out of which two electrons lies in 1S orbital (K shell) & one electron lies in 2S orbital. To attain the stability ( nobel configuration) lithium requires 7 electron which is not possible at ordinary condition & it requires a huge amount of energy instead lithium loses one electron from outermost shell.
We know that when any atom loses a electron the oxidation number is written with plus(+) symbol.
Hence net charge on lithium ion is +1
Answer:
A. Steel
Explanation:
Steel is a mixture of iron and carbon fused together with one or more other metals or nonmetals. Because steel is a mixture rather than a chemical compound, steel does not have a set chemical compound formula.
