Answer:???????????????????????? huh?
Explanation:
The answer is A. Every action has an equal and opposite reaction
Answer:
The organism died 35900 years ago
Explanation:
- Half life C-14 is 5730 years.
- For decay of radioactive nuclides:
is the fraction of radioactive nuclide remain present after t time and 
is the half-life of radioactive nuclide- Here is 0.013 and is 5730 yeras
Plug-in all the values in the above equation:
So, t = 35900 years
Hence the organism died 35900 years ago
The conjugate acid of ch3nh2 is ch3nh3+<span>.
</span>For example methylamine in water chemical reaction:
CH₃NH₂(aq)+ H₂O(l) ⇌ CH₃NH₃⁺(aq) + OH⁻(aq).
According
to Bronsted-Lowry theory acid are donor of protons and bases
are acceptors of protons (the hydrogen cation or H⁺). Methylamine (CH₃NH₂) is Bronsted base and it can accept proton and
become conjugate acid (CH₃NH₃⁺).
Answer: The oxidation state of selenium in SeO3 is +6
Explanation:
SeO3 is the chemical formula for selenium trioxide.
- The oxidation state of SeO3 = 0 (since it is stable and with no charge)
- the oxidation number of oxygen (O) IN SeO3 is -2
- the oxidation state of selenium in SeO3 = Z (let unknown value be Z)
Hence, SeO3 = 0
Z + (-2 x 3) = 0
Z + (-6) = 0
Z - 6 = 0
Z = 0 + 6
Z = +6
Thus, the oxidation state of selenium in SeO3 is +6
