Answer:
Mathematics is used in Physical Science to calculate the measurements of objects and their characteristics, as well as to show the relationship between different functions and properties. Arithmetic, algebra and advanced mathematics may be used.
Explanation:
High and low concentrations of hydrogen
Answer:
see below for explanation
Explanation:
1. you need to set up and balance the equation
NaOH + HC2H3O2 --> NaC2H3O2 + H2O
2. Write the value they gave you underneath the equation to figure out what we are solving for, which is the molarity of NaOH
<u>NaOH</u> (Base) + <u>HC2H3O2</u> (Acid)--> NaC2H3O2 + H2O
15.0 ml | 7.5ml
? M | 0.02M
3. Use the MaVa=MbVb ·
- This formula is saying the M of an acid times the volume of the acid = the M of the base times the volume of the base times the mol of the acid/ mol of the base ratio. ***You should always compute the volume in Liters.
- Convert your values (x is the molarity of the base, the unknown value) Our acid values are first because that is how the equation is set up
0.0075 · 0.02 = 0.0150 · x · 1/1
4. Simplify
0.00015 = 0.0150x
5. Solve
Molarity of the base = 0.01
Mass divided by Volume
-----
Density
Mainly the number of valence electrons is needed to represent an ionic compound also you need how to use the lewis dot diagram
