Answer:
i think Aluminum (Al) oxidized, zinc(Zn) reduced
Answer:
Arrhenius acid & Bronsted-Lowry acid
Explanation:
Answer:
3–methyl–2–butanol
Explanation:
To name the compound, we must:
1. Identify the functional group.
2. Give the functional group of the compound the lowest possible count.
3. Locate the longest continuous carbon chain. This gives the parent name of the compound.
4. Identify the substituent group attached.
5. Give the substituent group the lowest possible count.
6. Combine the above to get the name of the compound.
Now, let us obtain the name of the compound.
1. The functional group of the compound is Alcohol i.e —OH.
2. The functional group is located at carbon 2.
3. The longest continuous carbon chain is carbon 4 i.e butane. But the presence of the functional group i.e OH will replace the –e in butane with –ol. Therefore, the compound is butanol.
4. The substituent group attached is methyl i.e CH3.
5. The substituent group is located at carbon 3.
6. Therefore, the name of the compound is:
3–methyl–2–butanol.
Answer:
A compound is just pure that is composed of elements that are chemically bonded in definite proportions
andd solution is umm well its a homogenous so basically saying
that it all just stays the same all the way through
Explanation:
im not sure how else to explain it haah hope this helped :P
Answer:
0.071 mole
Explanation:
As discovered from Avogadro's hypothesis, 1 mole of any substance contains 6.02x10^23 molecules.
This simply means that 1 mole of H3PO4 also contains 6.02x10^23 molecules.
If 1 mole H3PO4 contains 6.02x10^23 molecules,
Then, xmol of H3PO4 will contain 4.3x10^22 molecules i.e
Xmol of H3PO4 = 4.3x10^22/6.02x10^23 = 0.071 mole
From the calculations made above, 4.3x10^22 molecules of H3PO4 have 0.071 mole of H3PO4
