The highest atom economy
2CO + O₂ ⇒ 2CO₂
<h3>Further explanation</h3>
Given
The reaction for the production of CO₂
Required
The highest atom economy
Solution
In reactions, there are sometimes unwanted products that can be said to be a by-product or a waste product. Meanwhile, the desired product can be said to be a useful product, which can be shown as the atom economy
of the reaction
the higher the atomic economy value of a reaction, the smaller the waste/ byproducts produced, so that less energy is wasted
The general formula:
Atom economy = (mass of useful product : mass of all reactants/products) x 100
<em>or
</em>
Atom economy = (total formula masses of useful product : total formula masses of all reactants/products) x 100
So a reaction that only produces one product will have the highest atomic value, namely the reaction in option C

Answer:
3.02
Explanation:
Step 1: Given and required acid
pH of the solution: 4.34
pKa of lactic acid: 3.86
Step 2: Calculate the ratio of the lactate concentration to the lactic acid concentration in this solution
We have a buffer system formed by a weak acid (lactic acid) and its conjugate base (lactate ion). We can find the ratio of the lactate concentration to the lactic acid concentration in this solution using the Henderson-Hasselbach equation.
pH = pKa + log [lactate]/[lactic acid]
4.34 = 3.86 + log [lactate]/[lactic acid]
[lactate]/[lactic acid] = 3.02
If ur talking about matter phases then it would i think be liquid, solid & gas but if you’re talking about classifying matters then hopefully this picture helps
