Chemical sanitizer effectiveness, decreases with increase in pH . And most soap and detergent are alkaline in nature, that limits its effectiveness. So they should be rinsed off completely for proper effectiveness of santizer. So improper rinsing limits the effectiveness of a sanitizer.
So , the answer is improper rinsing after that still a detergent residue remains limits the effectiveness of sanitizer.
I would say B and E as using electricity uses fossil fuels
Answer is: <span>to decrease activation energy.
Manganese(IV) oxide is catalyst in this reaction.
</span>Catalysis <span>is the increase in the </span>rate<span> of a </span>chemical reaction<span> due to the participation of an additional substance called a </span>catalyst. R<span>eactions occur faster with a catalyst because they require less </span>activation energy<span>.</span>
Answer:
35.9%
Explanation:
The percent volume of the coffee solution can be calculated as follows:
% volume of coffee solution = volume of coffee/total volume of coffee solution × 100
According to this question, a cup of coffee has 71 mL of coffee and 127 mL of water. This means that, the total volume of coffee solution is;
71mL + 127mL = 198mL
% volume = 71/198 × 100
= 0.359 × 100
Percent volume of coffee solution = 35.9%
Lithium. Electronegativty increases across the periodic table and increases down the periodic table.
