Answer:
Liquids take the shape of their containers because they are stuck together enough to not go flying off like gases but not so tightly that they stay in a stiff shape like solids do.
Explanation:
Hope this helps you! ^^
Answer:
Sr or Strontium
Explanation:
sr: strontium has atomic radius of 255pm
cu: copper has an atomic radius of 128pm
they teach you in chem how to do it based off the chart but I don't remember that method
H2O(s) ==> H2O(l)
<span>The density of liquid H2O = 1.00 g/mL. </span>
<span>The density of ice is 0.917 g/mL. </span>
<span>Suppose we start with 1 mol (18 g) H2O(s) and it melts to the liquid. </span>
<span>As a liquid it will occupy 18g/1.00 = 18 mL. </span>
<span>As a solid it will occupy 18/0.917 = 19.63 mL. </span>
<span>19.63-18.0 = 1.63 mL diffeence. </span>
<span>The heat fusion of ice is 6.01 kJ/mol; therefore, 6.01/1.63 = about 3.69 kJ for each mL difference. </span>
<span>In this experiment we have a difference of 0.109 mL; then 3.69 kJ/mL x 0.109 mL = 0.402 kJ for 0.0657 g Zn. You want per mol Zn and you have 0.0657/65.39 = about 0.001 mol Zn so </span>
0.402 kJ/0.001 = <span>402 kJ/mol Zn</span>
Explanation:
The reaction equation will be as follows.
Calculate the amount of dissolved as follows.
It is given that = 0.032 M/atm and = atm.
Hence, will be calculated as follows.
=
=
=
or, =
It is given that
As,
=
=
Since, we know that pH =
So, pH =
= 5.7
Therefore, we can conclude that pH of water in equilibrium with the atmosphere is 5.7.
