Answer: 3<u> H₂O</u>
<u />
Explanation:
This is an example of a common chemical reaction
ACID + CARBONATE --> SALT + WATER + CARBON DIOXIDE which implires
CITRIC ACID + SODIUM BICARBONATE ----> SODIUM CITRATE + WATER + CARBON DIOXIDE .
The full chemical equation is given by
H3C6H5O7(aq) + 3NaHCO3(aq) --> Na3C6H5O7(aq) + 3CO2(g) + 3<u>H2O</u>(l)
The reaction produces a fizz due to the release of carbon dioxide which can be also seem when an Alka-Seltzer® tablet is dissolved in water.
Answer:
B
Explanation:
The methyl prefix means theres a CH3 group bonded to a carbon in a hydrocarbon. This is called branching because it looks like a branched tree. This is literally cheating but you do you.
Answer:
![r = k . [CO] .[Cl_{2}]](https://tex.z-dn.net/?f=r%20%3D%20k%20.%20%5BCO%5D%20.%5BCl_%7B2%7D%5D)
Explanation:
Let´s consider the following reaction:
CO + Cl₂ ⇒ COCl₂
The general rate law is:
![r = k . [CO]^{m}. [Cl_{2}]^{n}](https://tex.z-dn.net/?f=r%20%3D%20k%20.%20%5BCO%5D%5E%7Bm%7D.%20%5BCl_%7B2%7D%5D%5E%7Bn%7D)
where,
r is the rate of the reaction
k is the rate constant
[CO] and [Cl₂] are the molar concentrations of each reactant
m and n are the reaction orders for each reactant
Since the reaction is first order in CO, m = 1. The overall order is the sum of all the individual orders. In this case, the overall order m + n = 2. Then,
m + n = 2
n = 2 - m = 2 - 1 = 1
The reaction is first order in Cl₂.
The rate law is:
![r = k . [CO]. [Cl_{2}]](https://tex.z-dn.net/?f=r%20%3D%20k%20.%20%5BCO%5D.%20%5BCl_%7B2%7D%5D)
