The enthalpy of atomization (also atomisation in British spelling) is the enthalpy change that accompanies the total separation of all atoms in a chemical substance (either a chemical element or a chemical compound)
Answer:
- Sodium Bicarbonate (β-3) + Vinegar
- Lead Nitrate + Potassium iodide
Explanation:
Baking Soda and vinegar cause an explosion, in which the bicarbonate and vinegar are replaced by nitrate (∨) and oxide (Ф.) When you combine lead nitrate (Δω) with potassium iron, you also see the ingredients you combined disappear, which shall cause a replace reaction
Answer:
Swelling of the red blood cells occurs.
Explanation:
- <u>Distilled water makes the blood hypotonic ,. that is a less concentrated solution, to the body tissues including the red blood cells. </u>
- Therefore the water will enter the red blood cells and may cause them to lyse or swell.
- <em>Additionally , water will enter the tissue spaces and cause sweling. </em>
- But in the case of a hypertonic solution , ( a salt or saline solution ) , <em>This swelling does not happen because the concentration of the saline will be equal or more than the blood. </em>
- Thus the water will flow only from the blood to the solution. <u>This will not cause swelling.</u>
- But too much of salt is also not recommended.
Answer: The concentration of the OH-, CB = 0.473 M.
Explanation:
The balanced equation of reaction is:
2HCl + Ca(OH)2 ===> CaCl2 + 2H2O
Using titration equation of formula
CAVA/CBVB = NA/NB
Where NA is the number of mole of acid = 2 (from the balanced equation of reaction)
NB is the number of mole of base = 1 (from the balanced equation of reaction)
CA is the concentration of acid = 1M
CB is the concentration of base = to be calculated
VA is the volume of acid = 23.65 ml
VB is the volume of base = 25mL
Substituting
1×23.65/CB×25 = 2/1
Therefore CB =1×23.65×1/25×2
CB = 0.473 M.
I took the mg and converted it to grams. That gave me .325 grams. I took that and multiplied that by 3628 grams. If I did my math correctly, the answer would be 1179.1. Rounded up, that would be 1179 aspirin tablets.
Hope this helps. :)
