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?

Polyatomic ions: CH_3COO^-, NO_3^-, NH^+, CN^-, Li^+, and OH^-

Monatomic ions: Ca^{2+, O^{2-, and Fe^{3+

<h3>Monoatomic vs Polyatomic Ions</h3>

In chemistry, monoatomic ions are ions that consist of only a single type of atom. They are usually positive or negatively charged and are otherwise known as simple ions. Examples include  Ca^{2+, O^{2-, and Fe^{3+

Polyatomic ions, on the other hand, are ions that consist of more than one atom, unlike monoatomic ions. The two or more atoms are covalently bonded and the entire structure behaves like a single chemical entity in reactions. Polyatomic ions are otherwise known as molecular ions.

Examples of polyatomic ions are  CH_3COO^-, NO_3^-, NH^+, CN^-, Li^+, and OH^-

Thus, from the diagram:

  • Polyatomic ions: CH_3COO^-, NO_3^-, NH^+, CN^-, Li^+, and OH^-
  • Monatomic ions: Ca^{2+, O^{2-, and Fe^{3+

In this experiment you will create solutions with different ratios of ethanol and water. What is the mole fraction of ethanol wh
Andrej [43]

Answer:

The mole fraction of ethanol is 0.6. A 10 mL volumetric pipette must be used for to measure the 10 mL of ethanol. The vessel should be clean and purged.

Explanation:

For calculating mole fraction of ethanol, the amount of moles ethanol must be calculated. Using ethanol density (0.778 g/mL), 10 mL of ethanol equals to 7.89 g of ethanol and in turn 0.17 moles of ethanol. The same way for calculate the amount of water moles (ethanol density=0.997 g/mL). 2 mL of water correspond to 0.11. The total moles are: 0.17+0.11=0.28. Mole fraction alcohol is: 0.17/0.28=0.6

Why is it important for the pH of blood to remain constant?
lesya692 [45]
It is important for the pH of blood to remain constant because your blood would ionize and burn up if the pH wasn't constant. And if the pH was too high, bacteria ( good and bad, and foreign) would end up dying, as well as yourself.
