Answer:

The respiratory system is a system in your body that is in charge of helping you breathe. the respiratory system is made up of airways, lungs, and blood vessels, these parts work together to get oxygen into your body. Our respiratory system is a vital system, as it lets us live and breathe.

The respiratory system helps you breathe, absorb oxygen, and it cleans waste gases. your respiratory system also has problems such as allergies, diseases, and infections. it helps you smell, gives you protection from dust and microbes entering your body through your mucus production, cilia ( small nasal hairs ), and coughing.

How many total atoms are in 0.680 g of P₂O5?

Ludmilka [50]

Answer: 2.88× $10^{24}$ atoms $P_{2}O_{5}$

Explanation: First, using stoichiometry, we must convert this from grams to moles, then from moles to atoms.

1. For the first step, we should also look at the periodic table to find the molar mass of the compound, then use that as the denominator.

$0.680g P_{2} O_{5} *\frac{1molP_{2} O_{5} }{141.948gP_{2} O_{5} } =4.79mol P_{2} O_{5}$

2. Now that it is converted to moles, we must convert it to atoms by multiplying it by Avogadro's number.

$4.79molP_{2} O_{5} *\frac{6.022X10^{23} }{1mol} =2.88*10^{24}$

With this information, we know that there are $2.88X10^{24}$ total atoms in 0.680 grams $P_{2} O_{5}$ .

I hope this helps! Pls give brainliest!! :)

In an electrolytic cell, the electrode that acts as a source of electrons to the solution is called the __________; the chemical

Romashka [77]

In an electrolytic cell, the electrode that acts as a source of electrons to the solution is called the <u>cathode</u>; the chemical change that occurs at this electrode is called <u>reduction</u>.

<h3>Define Electrolyte:-</h3>

An electrolyte is a material that separates into charged ions when it is in contact with water. Cations are positively charged ions. Anions are ions that are negatively charged. A substance that may conduct an electric current when melted or dissolved in water is known as an electrolyte.

<h3>Electrochemical cell </h3>

There are three main categories of electrochemical cells. the galvanic cell, the concentration cell, and the electrolytic cell. These cells all share the same four fundamental components. These are the elements

The electrolyte serves as the conduit for current flow between the anode and the cathode. In an aqueous solution, it normally is homogeneous, but in moist soil, the concentration or kind of dissolved compounds may vary locally.
The anode, which can conduct electricity and is in contact with the electrolyte, corrodes when it combines with the chemicals in the electrolyte.
A metal also contacts the electrolyte at the cathode. It is protected from corrosion rather than corroded.
Anode and cathode are connected by the conductor, which also completes the circuit.
