Hope this helps! chemical test is a qualitative or quantitative procedure designed to identify, quantify, or characterise a chemical compound or chemical group. It is used to see if the driver had presence of alcohol or drugs in their system
Answer:
E) rate of appearance of C = 0.45 M/s
rate of the reaction = 0.15 M/s
Explanation:
2A + B → 3C
Writing rate law for the reaction:
<u>Rate of reaction</u> = -
![\frac{d[A]}{dt}](https://tex.z-dn.net/?f=%5Cfrac%7Bd%5BA%5D%7D%7Bdt%7D)
= -![\frac{d[B]}{dt}](https://tex.z-dn.net/?f=%5Cfrac%7Bd%5BB%5D%7D%7Bdt%7D)
= 
![\frac{d[C]}{dt}](https://tex.z-dn.net/?f=%5Cfrac%7Bd%5BC%5D%7D%7Bdt%7D)
→ equation 1
Given that the rate of disappearance of A is 0.3 M/s
⇒ - = 0.3 M/s
⇒Rate of reaction = - = ×0.3 M/s
⇒<u>Rate of reaction = 0.15 M/s</u>
From equation 1, = - 
= ×0.3 M/s
⇒ = 0.45 M/s
or <u>the rate of appearance of C = 0.45 M/s</u>

Explanation:
The law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products. For example, the mass of sodium plus the mass of chlorine that reacts with the sodium equals the mass of the product sodium chloride.
