Answer:
0.1 and 0.2.
Explanation:
The person's blood is 0.1 decreases and become more acidic if it has a pH of 7.3 compared to its preferred 7.4 while on the other hand, the person's blood is 0.2 increases and become more alkaline it has a pH of 7.6rather than its preferred 7.4. There is 0.1 decrease and 0.2 increase in the pH of the person's blood. If the pH decreases so it means it moves towards more acidic whereas, if the pH increases there is moves towards alkaline.
Explanation:
1. N/A
2. The difference in color
3. It is making the solution less concentrated, usually by adding more liquid.
4. You need to find the concentration of the solution before it was diluted. Add more of the solvent to the solute as per needed.
5.
a 1 molar solution cannot be made by adding one mole of solute to 1 L of solvent. • Solutions of a desired molality are usually prepared by placing the appropriate amount of solute
I think its Ocean trench, not sure tho.
He was convinced of murder back in 2006, and his appeal for a retrial that was denied.
Answer:
1.89 g CaCO₃
Explanation:
You will have to use stoichiometry for this question. First, look at the chemical equation.
Na₂CO₃ + CaCl₂ ==> 2 NaCl + CaCO₃
From the above equation, you can see that for one mole of Na₂CO₃, you will produce one mole of CaCO₃. This means that however many moles of Na₂CO₃ you have in the beginning, you will have the same amount of moles of CaCO₃, theoretically speaking.
So, convert grams to moles. You should get 0.0189 mol Na₂CO₃. This means that you will get 0.0189 mol CaCO₃. I'm not sure what units you want the answer in, but I'm going to give it in grams. Convert moles to grams. Your answer should be 1.89 g.
