Answer:
Organic chemistry
Explanation:
Organic chemistry is part of the chemistry that studies carbon compounds, which also use organic compounds, which have characteristics.
Energy cannot be created nor destroyed. :)
Answer:
NH₄Cl form closer to the end of the tube from which HCl was released.
Explanation:
Ammonia and hydrogen chloride gas react to form ammonium chloride water which can be seen by the formation of intensified fumes.
HCl + NH₃ ⇒ NH₄Cl
Since, the ammonia gas has a lower molecular weight as compared to that of hydrogen chloride gas. According to Graham's law of diffusion, the diffusion rate is inversely proportional to the square root of the molecular mass of the gas. <u>Thus, ammonia will diffuse faster as compared to hydrogen chloride gas. So, the white fumes will form at the side of the hydrogen chloride gas as it's diffusion will be slower and ammonia will diffuse fast and reaches to the gas.</u>
Answer:
a. Rate constant: 1.2118x10⁻⁴ yrs⁻¹
b. The age of the object is 20750 years
Explanation:
a. We can solve the rate constant in an isotope decay by using Half-Life, as follows:
K = Ln 2 / Half-life
K = ln 2 / 5720 years =
<h3>1.2118x10⁻⁴ yrs⁻¹</h3><h3 />
b. The general equation of isotope decay is:
Ln [A] = -kt + Ln [A]₀
<em>Where [A] is concentration of the isotope after time t, </em>
<em>k is rate constant</em>
<em>and [A]₀ initial concentration of the isotope.</em>
<em />
Computing the values of the problem:
Ln [0.89x10⁻¹⁴] = -1.2118x10⁻⁴ yrs⁻¹t + Ln [1.1x10⁻¹³]
-2.5144 = -1.2118x10⁻⁴ yrs⁻¹t
20750 years = t
The age of the object is 20750 years
