I think the correct answer would be direct additives. Not proper handling of cleaning agents especially in areas where food are prepared or served would most likely add chemicals to the food which is harmful to the consumer. Hope this helps.
Answer:
84.27 g
Explanation:
<em>How many grams of hydrogen are in 10.45 moles of C₃H₈?</em>
Step 1: Calculate the moles of atoms of hydrogen
The molar ratio of C₃H₈ to H is 1:8.
10.45 mol C₃H₈ × 8 mol H/ 1mol C₃H₈ = 83.60 mol H
Step 2: Calculate the mass corresponding to 83.60 moles of hydrogen
The molar mass of hydrogen is 1.008 g/mol.
83.60 mol × 1.008 g/mol = 84.27 g
Strong acids are those that dissociate completely into their ions. So the dissociation equation for a strong acid is:
HA → H⁺ + A⁻
It is visible from the equation that the number of moles of hydrogen ions released is equivalent to the number of moles of acid. For a given volume,
[HA] → [H]⁺ + [A]⁻
Thus, the assumption is logical and fairly accurate
Tell the teacher they have touched an unidetified liquid. This is because "hiro" can have a reaction with the chemical he touched that can harm his health.
The original change is chemical, affecting the main colorant because of temperature. Paint, is a surface change, not changing anything about the leaf itself, but showing a different color to your eye.
