You should make a density trap, you get different liquids with different density's ( corn starch , water , alcohol , syrup) and pour them into a big vase and the different density's will sit on top of each other . the best thing to do is to use food coloring so that each level is a different color.
Answer:
7g
Explanation:
Given parameters:
Mass of sodium = 3g
Mass of chlorine = 4g
Unknown:
Total mass of sodium chloride = ?
Solution:
This problem entails the direct application of the law of conservation of mass. According to this law, it states that "matter is neither created nor destroyed in the course of a chemical reaction".
So, when sodium and chlorine combines to form sodium chloride, to are expect to produce substance with a mass which adds up to the sum of the reactants;
Mass of sodium chloride = mass of sodium + mass of chlorine
= 3g + 4g
= 7g
Polar bond
Explanation:
The bond between P-Cl is a polar covalent bond type. A covalent bond occurs between non-metals with an electronegativity difference less than a value of 1.7.
This implies that for a compound of P-Cl to form, both atoms donate electrons. The electrons are shared and in the process a covalent bond forms.
- Polarity occurs when an atom attracts the shared electron closely to itself more than the other.
- The attraction is based on the level of electronegativity between the two atoms.
- The electronegativity is used to estimate the readiness of an atom to attract electrons to itself in a bond.
- Chlorine is more electronegative than Phosphorus.
- This leaves a partial positive charge on phosphorus and a partial negative charge on chlorine.
This way, the compound has a charge separation into positive and negative.

Answer:
0.0042 M is the molarity of tartaric acid in this sample of wine.
Explanation:
To calculate the concentration of acid, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is tartaric acid
are the n-factor, molarity and volume of base which is NaOH.
We are given:
Putting values in above equation, we get:
0.0042 M is the molarity of tartaric acid in this sample of wine.
