The water well begin to freeze and turn into soild. why? because the temperature of the the freezer is getting the water bottle cold so when that cold temperature hits that that bottle which has liquid in it so you should know that when liquid is into cold air it well so be soild so when you put the water bottle in the freezer it will be soild.
and also remember gas - liquid - soild gas change to liquid by hot air and liuid change to soild by clod air
hoped i helped
Answer:
Option (A) Each Zn atom loses 2 electrons, and each Co2+ ion gains 2
Explanation:
To know the right answer to the question, let us observe the changes in the oxidation number of Zn and Co. This is illustrated below:
Zn(s) + Co2+(aq) → Zn2+(aq) + Co(s)
The oxidation number of Zn changes from 0 to +2 indicating that Zn has lose 2 electrons.
The oxidation number of Co changes from +2 to 0 indicating that Co has gain 2 electrons.
Therefore, option A is the correct answer.
The one with the highest pH would be a solution with 100 mL of water and also 20 mL of 0.1 M NaOH is added. Solutions without buffers would have the highest pH since the resistance to change is very low. Hope this answers the question.
Answer:
Solids
Explanation:
At standard room temperature and pressure, most of the elements are solids.
Just a few of the elements are liquids and gases at this temperature.
The periodic table is made up of metals, metalloids and non-metals. Most of these substances are actually solid.
Some non-metals are gaseous at standard room temperature.
N=3^K-1 I really don't know how to explain it but that's the formula <span />
