<u>Answer:</u> The volume of concentrated hydrochloric acid solution is 1.73 mL
<u>Explanation:</u>
To calculate the hydrogen ion concentration of the solution, we use the equation:
![pH=-\log[H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%5BH%5E%2B%5D)
We are given:
pH = 1.60
Putting values in above equation, we get:
![1.60=-\log [H^+]](https://tex.z-dn.net/?f=1.60%3D-%5Clog%20%5BH%5E%2B%5D)
![[H^+]=10^{-1.60}=0.0251M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D10%5E%7B-1.60%7D%3D0.0251M)
To calculate the volume of the concentrated solution, we use the equation:
where,
are the molarity and volume of the concentrated HCl solution
are the molarity and volume of diluted HCl solution
We are given:
Putting values in above equation, we get:
Hence, the volume of concentrated hydrochloric acid solution is 1.73 mL
Answer:
d
Explanation:
because nuclear charge ( no. of protons) increases
Magnesium
Answer:
Rock
Explanation:
Rock -
It refers to the naturally occuring mass of mineral , with a uniform chemical composition , is referred to as a rock .
In the crust of the Earth , the composition is by the igneous rocks .
<u>There are three main type of rocks , i.e. , </u>
- sedimentary rocks ,
- metamorphic rocks ,
- igneous rocks .
Hence , from the given information of the question ,
The correct term is rock.
Based on the picture, the way that chemical bonds form in the substance is :
K loses an electron and Br gains an electron.
This created difference in charges, which create attraction
hope this helps
