Answer:
Physical science, in turn, can be divided into chemistry and physics. Chemistry is the study of matter and energy at the scale of atoms and molecules. ... Physics is the study of matter and energy at all scales—from the tiniest particles of matter to the entire universe but i dont really know if there is new information to discover
Explanation:
hope it help and if it doesnt sorry ;)
Answer:
Explanation:
As an example, the following cell reaction: Zn(s) + Cu2+(aq) → Zn2+(aq) + Cu(m) generates a cell voltage of +1.10 V under standard conditions. Calculate and enter delta G degree (with 3 sig figs) for this reaction in kJ/mol.
Zn(s) + Cu2+(aq) → Zn2+(aq) + Cu(m)
ΔG = ΔG° + RTInQ
Q = 1
ΔG = ΔG°
ΔG = =nFE°
n=no of electrons transfered.
E° = 1.1v
ΔG° = -2 * 96500 * 1.10
= -212300J
ΔG° =-212.3kJ/mol
<h3>Therefore, the ΔG° = -212.3kJ/mol</h3>
Answer:
You can boil or evaporate the water and the salt will be left behind as a solid. If you want to collect the water, you can use distillation. This works because salt has a much higher boiling point than water. One way to separate salt and water at home is to boil the salt water in a pot with a lid.

Answer:
Conducts electricity
Explanation:
an acid or base which strongly conducts electricity contains a large number of ions and is called a strong acid or base and an acid or base which conducts electricity only weakly contains a few ions and his called a weaker acid base
<u>Given:</u>
The number of particles = 3.131 * 10²⁴
<u>To determine:</u>
The number of moles corresponding to the given particles
<u>Explanation:</u>
1 mole corresponds to Avogadro's number of particles = 6.023 * 10²³ particles
Therefore, the given particles would correspond to:
3.131* 10²⁴ particles * 1 moles/6.023 * 10²³ particles = 5.199 moles
Ans: A) 5.199 moles are contained in 3.131* 10²⁴ particles
