Answer:
x = 33.52 amu
Explanation:
It is given that,
Isotope A has a mass of 34 amu and an abundance of 52%, isotope B has a mass of 33 amu and an abundance of 48%.
Let x is the average atomic mass of this element. It can be calculated as follows :
So, the average atomic mass of this element is 33.52 amu.
Answer;
- A 100 mL graduated cylinder since it has marks showing the volume of the substance measured.
Explanation;
-A graduated cylinder or a measuring cylinder is a common piece of laboratory equipment used to measure precise volumes of a liquid.
-Graduated cylinders are specifically designed to measure out liquid volumes. Their tall narrow design makes for a more precise reading of the liquid level as compared to other pieces used to measure volume.

Answer:</h3>
LiOH(aq) +HCl(aq)→ LiCl(aq) + H₂O(l)
Salt formed is LiCl
<h3>
Explanation:</h3>
- Arrhenius acid refers to a substance that ionizes in water to generate protons or hydrogen ions.
- Examples of Arrhenius acid include acids such as HCl, H₂SO₄ and HNO₃.
- A reaction between Lithium hydroxide and an Arrhenius acid such as HCl will yield a salt and water.
That is;
LiOH(aq) +HCl(aq)→ LiCl(aq) + H₂O(l)
- The salt formed is LiCl
- The reaction is an example of neutralization reaction.
Answer:
Measuring the Volume of Solids
Rectangular prism - Multiply the measurement of the length times the width, then times the height.
Cube - Since all sides are the same measurement, it would be the measurement of any side, or edge, cubed, or a³
Explanation:
