Answer:
the number of neutrons in above isotope = A - Z = 27 - 13 = 14. Note: The molar mass of aluminium, which is average of atomic masses of all isotopes = 26.981538 g/mol, since 13Al27 is the major isotope.
Explanation:
A. 0.12 (mol/L)/s
rate = 1 x 10-2 • 2^2 • 3
Answer:
Mendel's gene involved in pea color decides whether the chlorophyll in the pea will be broken down or degraded. When this gene isn't working, the chlorophyll stays around and the pea is green. So in this case the recessive trait is indeed due to a broken gene.
Explanation:
Answer:
D) HCOOCH2CH3
Explanation:
An isomer of a compound is defined as a chemical substances with the same formula (That is, same atoms) but in different structures.
For propanoic acid, there are <em>3 atoms of C, 6 atoms of H and 2 atoms of oxygen.</em>
A) CH2CHCOOH
. Here you have 3 atoms of C but 4 atoms of H. That means this compound is not an isomer.
B) CH3CH2CH2COOH
. Here, there are 4 atoms of C. Thus, is not an isomer.
C) CH3CH(OH)CH2OH. This structure has 3 atoms of C, but 8 atoms of H. Thus, is not an isomer.
D) HCOOCH2CH3. Here, there are 3 atoms of C, 6 atoms of H and 2 atoms of O. Thus, this structure <em>is an isomer of propanoic acid.</em>
Explanation:
1 is a process that occurs when gases in earth's atmosphere trap the sun's heat .
2 . heat in the atmosphere to warm the planet .
I only know the first too sorry ✨
