1. Elements are ordered by their properties.
2. The symbol is Si. Elemental symbols have no more than 2 letters(except for unidentified elements), and only the first letter is capitalized.
3. All atoms of an element are alike.
4. Metals are shiny and can conduct. They are found on the left side of the periodic table.
5. The most recent model is the Electron Cloud model, or the Schrödinger model.
6. Nonmetals are dull and don’t conduct.
7. MULTIPLE elements conjoin to form compounds. If all the atoms are the same, it’s still an element.
8. I can’t see the picture, sorry.
9. In order for a reaction to take place, energy must be present. This can be in the form of heat, though, but it’s not universal.
10. Enzymes are catalysts that speed up chemical reactions.
Answer:
-) 3-bromoprop-1-ene
-) 2-bromoprop-1-ene
-) 1-bromoprop-1-ene
-) bromocyclopropane
Explanation:
In this question, we can start with the <u>I.D.H</u> (<em>hydrogen deficiency index</em>):
In the formula we have 3 carbons, 5 hydrogens, and 1 Br, so:
We have an I.D.H value of one. This indicates that we can have a cyclic structure or a double bond.
We can start with a linear structure with 3 carbon with a double bond in the first carbon and the Br atom also in the first carbon (<u>1-bromoprop-1-ene</u>). In the second structure, we can move the Br atom to the second carbon (<u>2-bromoprop-1-ene</u>), in the third structure we can move the Br to carbon 3 (<u>3-bromoprop-1-ene</u>). Finally, we can have a cyclic structure with a Br atom (<u>bromocyclopropane</u>).
See figure 1
I hope it helps!
Answer:
any thing under 212 degrees Fahrenheit
Explanation:
the boiling point of water is 212 degrees Fahrenheit so any thing below this would be a non example.
Answer:
2) 0.109 mol
Explanation:
The density of butan-1-ol is 0.8098g/mL. And its molar mass is: 74.121g/mol.
First, we need to convert volume of butan-1-ol to mass:
10.0mL * (0.8098g / mL) = 8.098g of butan-1-ol
Now, we need to convert these grams to moles using molar mass:
8.098g * (1mol / 74.121g) = 0.109 moles of butan-1-ol
Right answer is:
<h3>2) 0.109 mol
</h3>
