Answer:
1) Capillary action
2) Cohesion
3)Miniscus
4) Adhesion
5) Viscousity
6) Surface tension
Explanation:
Intermolecular forces are forces that holds molecules together in liquid, these is possible by inter-molecular interactions that exist within the liquids.these forces includes forces such as Waals forces and hydrogen bonds.
When there is great inter-molecular forces, there will be high freezing point and boiling point . At a lower inter-molecular forces the boiling point becomes low too,which brings about great fluidity of the liquid. The liquid flow reluctantly where greater force exist in the liquid. Some of those factors used in characterizing which are;
1)adhesion,
2) surface tension,
3)capillary action,
4)cohesion,
5) meniscus,
6)viscosity.
The balanced chemical equation for the standard formation reaction of liquid acetic acid is given as ,
→
The reaction that form the products from their elements in their standard state is called formation of reaction .The acetic acid consist C , H , and O , So, determine their standard state . Carbon is graphite at 25°C and 1 atm , whereas hydrogen and oxygen are diatomic gases . Hence , we start with unbalanced reaction.

N(NaOH)=0.0688 mol
v=0.250 L
c=n(NaOH)/v
c=0.0688/0.250=0.2752≈0.28 mol/L
0.28 M
Insulation wraps because independent is the variable you are changing to affect the dependent variable (what you are measuring)
Answer:
F = 50 N
Explanation:
Given data:
Mass of car = 250 Kg
Acceleration of car = 0.20 m/s²
Force required = ?
Solution:
Formula:
F = m×a
F = applied force
m = mass
a = acceleration
Now we will put the values in formula.
F = 250 Kg × 0.20 m/s²
F = 50 Kg.m/s²
Kg.m/s² = N
F = 50 N
