Amphetamine was developed initially as a substitute for a closely-related chemical derived from the Chinese herb ma huang. That chemical is Ephedrine.
<h3>
What is Ephedrine?</h3>
Ephedrine is a stimulant medication that can be considered an amine chemical compound and substituted amphetamine.
Ephedrine is used in sports to stimulate the central nervous system (C_NS) and as energy supplier.
Ep_hedrine use is prohibited and chronic usage of this substance may have problems the health.

Answer:
2.6 kJ
Explanation:
The formula for the amount of heat (q) absorbed by the water is
q = mCΔT
1. Calculate ΔT
ΔT = 23.5 °C - 22.1 °C = 1.4 °C
2. Calculate q
q₂ = mCΔT = 500 g × 4.184 J·°C⁻¹g⁻¹ × 1.4 °C = 2900 J = 2.9 kJ
Answer: D is the answer since it is the product of this equation

Answer:
The answer to the question is
The rate constant for the reaction is 1.056×10⁻³ M/s
Explanation:
To solve the question, e note that
For a zero order reaction, the rate law is given by
[A] = -k×t + [A]₀
This can be represented by the linear equation y = mx + c
Such that y = [A], m which is the gradient is = -k, and the intercept c = [A]₀
Therefore the rate constant k which is the gradient is given by
Gradient =
where [A]₁ = 8.10×10⁻² M and [A]₂ = 1.80×10⁻³ M
=
= -0.001056 M/s = -1.056×10⁻³ M/s
Threfore k = 1.056×10⁻³ M/s
