Answer:
We need 78.9 mL of the 19.0 M NaOH solution
Explanation:
Step 1: Data given
Molarity of the original NaOH solution = 19.0 M
Molarity of the NaOH solution we want to prepare = 3.0 M
Volume of the NaOH solution we want to prepare = 500 mL = 0.500 L
Step 2: Calculate volume of the 19.0 M NaOH solution needed
C1*V1 = C2*V2
⇒with C1 = the concentration of the original NaOH solution = 19.0 M
⇒with V1 = the volume of the original NaOH solution = TO BE DETERMINED
⇒with C2 = the concentration of the NaOH solution we want to prepare = 3.0 M
⇒with V2 = the volume of the NaOH solution we want to prepare = 500 mL = 0.500 L
19.0 M * V2 = 3.0 M * 0.500 L
V2 = (3.0 M * 0.500L) / 19.0 M
V2 = 0.0789 L
We need 0.0789 L
This is 0.0789 * 10^3 mL = 78.9 mL
We need 78.9 mL of the 19.0 M NaOH solution
Soil acidification is a circumstance which will most likely lead to a change in the nutrient cycling that will have a detrimental impact on plant growth.
<h3>What is the main use of nitrogen?</h3>
The chemical industry depends on nitrogen. It is used to create explosives, nylon, nitric acid, fertilizers, and colors. N must first be combined with hydrogen to create ammonia in order to create these products. The Haber process is used for this. Similar to chlorine gas and carbon monoxide poisoning, nitrous oxide poisoning is detrimental to all living things.
<h3>Why is nitrogen poisonous?</h3>
Effects on health. The majority of greater nitrogen oxides are irritants to the eyes, skin, and respiratory system. Except at deadly quantities, where arginine may kill more quickly, no2 is a corrosive chemical that, when in contact with water, produces nitric and nitrous acids.
