I think because its the only one to be liquid at normal temperatures.
1.) protons neutrons and electrons
2.) a wall outlet it is made up of metal that conducts heat. When when heat is applied it provides enough energy to these electrons
3.) is an imbalance if electric charges within or on the surface of a material
4.) static electricity decoded tiny changes in the surface of a balloon causes it to charge more when rubbed against our hair
5.) you might have to answer that on your own but if you don’t want to here’s my experience
One day me and my twin brother were jumping on the trampoline and when we fell down my hair rubbed against the surface of it and stuck up
Hope that helped and Brainiest?
1)They are all take up space.
2)They all have mass.
3)They are all solids.
Because of 1 and 2, they are all matter.
Answer : The concentration of A after 80 min is, 0.100 M
Explanation :
Half-life = 20 min
First we have to calculate the rate constant, we use the formula :
Expression for rate law for first order kinetics is given by:
where,
k = rate constant = 
t = time passed by the sample = 80 min
a = initial amount of the reactant = 1.6 M
a - x = amount left after decay process = ?
Now put all the given values in above equation, we get
Therefore, the concentration of A after 80 min is, 0.100 M
