Answer:
Yes; mayonnaise is a liquid.
Explanation:
This is because, when you smear it on a slice of bread, it moves freely. Like ketchup, when you put it on your plate. Is ketchup a liquid? Yes, it is. So yes, mayonnaise is most definitely a liquid.

Hi sweetie, hope this helps!
The more salt that is dissolved in the water, the less oxygen will be dissolved in it.
The higher the temperature of the water, the less oxygen will be dissolved it in.
Goodluck!,

Answer:
<h2>14.49 moles</h2>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
![n = \frac{N}{L} \\](https://tex.z-dn.net/?f=n%20%3D%20%20%5Cfrac%7BN%7D%7BL%7D%20%5C%5C)
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
![n = \frac{8.72 \times {10}^{24} }{6.02 \times {10}^{23} } \\ = 14.48504...](https://tex.z-dn.net/?f=n%20%3D%20%20%5Cfrac%7B8.72%20%5Ctimes%20%20%7B10%7D%5E%7B24%7D%20%7D%7B6.02%20%5Ctimes%20%20%7B10%7D%5E%7B23%7D%20%7D%20%20%5C%5C%20%20%3D%20%2014.48504...)
We have the final answer as
<h3>14.49 moles</h3>

<u>Answer:</u>
<u>For a:</u> The chemical equation for the dissolution of sodium carbonate is ![Na_2CO_3(s)\rightarrow Na_2CO_3(aq.)](https://tex.z-dn.net/?f=Na_2CO_3%28s%29%5Crightarrow%20Na_2CO_3%28aq.%29)
<u>For b:</u> The net acid-base reaction is ![CO_3^{2-}(aq.)+H_2O(l)\rightarrow OH^-(aq.)+HCO_3^-(aq.)](https://tex.z-dn.net/?f=CO_3%5E%7B2-%7D%28aq.%29%2BH_2O%28l%29%5Crightarrow%20OH%5E-%28aq.%29%2BHCO_3%5E-%28aq.%29)
<u>Explanation:</u>
Dissolution reaction is defined as the reaction in which a solid compound gets dissolved in water to form aqueous solution.
The chemical equation for the dissolution of sodium carbonate follows:
![Na_2CO_3(s)\rightarrow Na_2CO_3(aq.)](https://tex.z-dn.net/?f=Na_2CO_3%28s%29%5Crightarrow%20Na_2CO_3%28aq.%29)
Ionization reaction is defined as the reaction in which an ionic compound dissociates into its ions when dissolved in aqueous solution.
The chemical equation for the ionization of sodium carbonate follows:
![Na_2CO_3(aq.)\rightarrow 2Na^+(aq.)+CO_3^{3-}(aq.)](https://tex.z-dn.net/?f=Na_2CO_3%28aq.%29%5Crightarrow%202Na%5E%2B%28aq.%29%2BCO_3%5E%7B3-%7D%28aq.%29)
Now, the anion formed which is
reacts with water to form conjugate acid.
The chemical equation for the reaction of anion with water follows:
![CO_3^{2-}(aq.)+H_2O(l)\rightarrow OH^-(aq.)+HCO_3^-(aq.)](https://tex.z-dn.net/?f=CO_3%5E%7B2-%7D%28aq.%29%2BH_2O%28l%29%5Crightarrow%20OH%5E-%28aq.%29%2BHCO_3%5E-%28aq.%29)
Hence, the net acid-base reaction of the anion formed and water is written above.
